WELCOME TO UIS2/UIS OPTICS
UIS2/UIS:
The System That Maximizes The Advantage Of Infinity-Corrected Optics
What's infinity-corrected optics?
light between the objective lens and tube lens,
allowing the creation of user-specific or taskspecific optical systems. To establish real flexibility
with such a system, it is necessary to eliminate the
occurrence of coma aberration.
UIS2/UIS optics is an infinity-corrected optical
system — in other words, a system in which light
passes from the specimen through the objective
lens without forming an image along the way.
Instead, it travels in the form of infinity parallel rays
to the tube lens. The tube lens is where the
intermediate image is formed, whereas in finitecorrected optics, this is done by the objective lens.
*In UIS2/UIS objective lenses, the parfocal distance is designed
at 45mm and the focal length of the tube lens is 180mm.

Eyepiece
The UIS2/UIS optical system optimally corrects
aberration with a dedicated telan lens and an
eyepiece so that the coma aberration and flatness
are not degraded even when the telan lens exit
pupil position is changed by changing the
objective lens and telan distance. This makes it
possible to use a distance of 50mm to 170mm
from objective lens mounting position to the single
port tube with lens.

Advantages of infinity-corrected optics
This system, known as "infinity-corrected optics",
offers a number of advantages:
*Coma aberration: refer to the optical terminology at the end of
• There is no change in magnification even when
the distance between the objective lens and tube
lens is altered.
• With the total magnification remaining constant,
there is no image aberration — even when
prisms or sliders are interposed between the
objective lens and the tube lens.

WELCOME TO UIS2/UIS OPTICS
Features of UIS2 objective lenses
4. Lightening
Weight has been reduced to approximately 2/3
that of conventional products by using an
aluminum objective lens barrel cover. This has
the effect of lightening the load on the devices at
objective lens up/down, suppressing vibrations
by lowering the inertial force at objective lens
switching, etc. (MPLFLN series, LMPLFLN
series)
UIS2 objective lenses ensure compatibility (screw
diameter, optical performance) with the UIS optical
system and have the following features compared
to conventional objective lenses.
1. Wavefront aberration control
The Olympus UIS2 objective lenses set a new
standard, with wavefront aberration control in
addition to common performance standards of
N.A. and W.D. Olympus challenges farther
highest order optics which has not been fulfilled
by the conventional standards. We offer
excellent performance objective lenses by
minimizing the aberrations that lower resolution.
5. Adoption of eco-lens
The glass materials of UIS2 objective lenses are
all lead- and cadmium-free eco-glass.
Based on our conviction that the UIS2/UIS
system is the best way to maximize the
advantages of infinity-corrected optical
systems, we confidently recommend the
UIS2/UIS-featured Olympus microscope units
for all your high-precision needs in research,
inspection and production equipment.
*Wave front aberration: refer to the optical terminology at the
end of this document.
2. Objective lenses with excellent image
parcentricity
High power SemiApochromatic UIS2 objective
lenses make the centration tolerance between
objective lenses on the microscope nosepiece
keep the image within the enter of the field of
view even with digital cameras. (50x or higher
power in both MPLFLN and LMPLFLN series)
* Refer to the Olympus home page for detailed
objective lenses specifications.
3. Improvement of color reproducibility
UIS2 objective lenses realize natural color
reproduction without any chromatic shifts using
stringently selected high transmittance glass
and advanced coating technology that provides
high transmittance which is flat over an ultrawide band wavelength. In addition, since the
total optical system, including the tube lens is
designed to reproduce a natural color, clear
images faithful to the specimen are obtained
even with digital imaging.

Long WD M Plan SemiApochromat
(WD: Working Distance)
LMPLFLN series
Long working distance Plan SemiApochromat objective lenses, giving high-level correction for chromatic aberration.
Suitable with samples having a height difference and in preventing collision, as the working distance is long.
Also, since the exit pupil position of the 5x-100x objective lenses is standardized, the position of the DIC prism does not have
to be switched when changing the magnification.

The field number (F.N.) is referred to as the diaphragm size of
eyepiece in mm unit which defines the image area of specimen.
The diaphragm diameter actually seen through eyepiece is
known as the practical field of view (F.O.V.) which is determined
by the formula:
5.1 Observation through eyepiece (binocular observation)

8. Focal depth of Microscope
6. Numerical Aperture (N.A.)
The focal depth refers to the depth of the specimen layer which
is in sharp focus at the same time, even if the distance between
the objective lens and the specimen plane is changed when
observing and shooting the specimen plane by microscope. As
human eyes are individually different in the ability of their focus
adjustment, each person's perception of the focal depth varies.
At present, the Berek formula is generally used, because it gives
a focal depth value that often coincides with that obtained
through experiments.
The numerical aperture is a key factor to the performance of
objective lens (resolving power, focal depth and brightness).
The N.A. is determined by the following formula:
N.A.= n × sinθ
n=Refraction rate of the medium between specimen and
objective lenses. (Air: n=1, oil: n=1.515)
θ: Angle which is made by the optical axis and refraction of the
light farthest from the center of the lens.
Focal depth formula
● Visual observation (Berek formula)
The visual field brightness (B) of the microscope is determined
by the following formula in relation to the objective lens
magnification (M). The larger the N.A. and the lower the
objective magnification, brightness will increase in the factor of
the second power.

7. Resolving Power
● Video camera
In the case of a video camera, the focal depth will vary according
to number of pixels of CCD, optical magnification, and numerical
aperture. The above-mentioned formula is used as a rough
guide only.
The resolving power of an objective lens is measured by its
ability to differentiate two lines or points in an object. The greater
the resolving power, the smaller the minimum distance between
two lines or points that can still be distinguished. The larger the
N.A., the higher the resolving power.

“Expansion of a point image” can also be expressed by
“wavefront aberration” that regards the light as “waves” and
takes account of the phase to include the influence of diffraction.
9. Aberrations
A difference between an ideal image and an actual image that
passes through an optical system is called an “aberration.”
(1) Spherical aberration
When light rays coming out of an axial object point enter a lens,
the light rays with a larger numerical aperture (N.A.) are
subjected to stronger refraction power and cross the optical axis
in positions with larger differences from the ideal image
formation position. The aberration caused this way by different
image forming positions due to differences in N.A. of axial light
rays is called “spherical aberration.” (“Spherical aberration” is
proportional to the cube of N.A.)
9.1 Requirements for Ideal Image Formation
The following three requirements must be satisfied to form an
image with no aberration, or an ideal image.
(i) All the light rays coming from a single point and passing
through an image formation optical system converge on a
single point.
(ii) Image points, which correspond to object points on the
same plane perpendicular to the optical axis, are present
on the same plane.
(iii) The planar shape of an object and the planar shape of an
image that are on the same plane perpendicular to the
optical axis have a similarity relation.

Objective lens with
spherical aberration
It is said that objective lenses with larger N.A. have better
resolution but worsen spherical aberration. Our advanced
design and manufacturing techniques have realized good optical
performance even with large numerical aperture.
In an actual optical system, however, it is very difficult to strictly
meet the requirements for ideal image formation and this causes
“aberrations” that interfere with image forming performance.
(2) Coma aberration
Even though spherical aberration is compensated to be very
small, there are cases where light rays coming out of an off-axis
object point are not condensed to a single point on the image
plane but generate asymmetric blur just like a comet leaving
traces. This is called coma aberration.
9.2 Classification of Aberrations
Aberrations that interfere with image forming performance are
classified as shown below in Figure 9-2.

“Curvature of image plane” + “Deformation”

(3) Astigmatism
Even though a lens is compensated for spherical aberration and
coma aberration, there are cases where an image of an off-axis
object point is not focused to a single point but separated to a
concentric line image and a radial line image. This is called
“astigmatism.” When astigmatism is present, a point image
blurs vertically and horizontally, before and after the focus
position.
Types (1) to (3) correspond to “expansion of a point image” that
goes against requirement (i) for ideal image formation in Figure 91. Type (4) corresponds to “curvature of image plane” that goes
against requirement (ii) in Figure 9-1. Type (5) corresponds to
“deformation” that goes against requirement (iii) in Figure 9-1.

Many special glass materials are used, e.g., for apochromats
(MPlanApo in Olympus), to eliminate chromatic aberration in a
wide range from violet light (g-rays with wavelength of 435 nm)
to red light (c-rays with wavelength of 656 nm).

9.3 Wavefront Aberration
Since a long time ago, aberrations have been used in “geometric
optics,” which considers light as “light rays.” Microscope optical
systems are often used for observation of very small specimens
at a wavelength level, and sometimes adopt “wave optics,”
which regards light as “waves” and handles the phase
information, taking account of the influence of diffraction.
In such a case, “wavefront aberration” is used for evaluation.
As shown below, when requirements for ideal imaging are
satisfied in a microscope optical system, the spherical wavefront
(spherical waves) coming from a single point on an object
(specimen) is converted to plane waves through an ideal
objective lens. The plane waves are converted to spherical
waves through an ideal tube lens, and condensed to a single
point. The wavefront of these waves is called the “ideal
wavefront.”

(4) Field curvature
An image plane of an object on a plane perpendicular to an
optical axis does not always become a plane perpendicular to
the optical axis, but it generally becomes a curved plane. This
symptom is called “field curvature.”
When field curvature is present, the image is more displaced as
it becomes closer to the periphery of the visual field. Therefore,
when the center of an image is brought into focus, blur occurs in
the peripheral areas of the image. To bring the entire image,
including the periphery, into clear focus, it is necessary to
adequately compensate for this type of aberration.

(5) Distortion
When there is no similar relation between a planar shape on an
object and a shape on the image plane, this is called “distortion.”
When distortion is present, a square image appears in a shape
of a barrel or pin-cushion as shown in Figure 9-6.

The microscope optical system contains some distortion. When
distortion is present, it can bring erroneous results of shape
measurements. When a microscope is used for precision
measurements, pay close attention to this aberration, for
example, by providing it with an aberration compensation
function.

A difference (a degree of disagreement) between the ideal
wavefront and the actual wavefront shown above is called
“wavefront aberration.”
(6) Chromatic aberration
Glasses used for optical systems have different refractive
indexes depending on the wavelength. This causes differences
in focal length between wavelengths and generates
displacement of image forming position. This phenomenon is
called “chromatic aberration,” which is sometimes subdivided
into axial displacement on the optical axis, called “axial
chromatic aberration” (or lateral chromatic aberration) and
displacement on the image plane, called “chromatic

9.4 Strehl ratio
When a point light source is observed with an aberration-free
optical system and an aberrated optical system , the former
concentrates the focal point to a point at the image formation
position. In contrast, the latter fails to produce a focal point,
instead causing a spread in the intensity distribution of the point
image (this is known as “point spread”). The specific
appearance of such a point image (i.e. point spread) is shown in
Fig. 9-9.

the image plane (point spread)
Aberration-free optical system
Aberrated optical system
With the proportion of light concentrated in the image plane
(intensity of light concentrated in the Airy disk) by an aberrationfree optical system serving as 100%, the proportion of light
concentrated by an aberrated optical system is known as the
Strehl ratio. When graphed, the Strehl ratio reveals peaks in
intensity as shown in Fig. 9-10. The higher the SR, the closer an
optical system is to being aberration-free.

A Strehl ratio of 80% is typically called the diffraction limit, and
lenses with a lower ratio lack the performance required to serve
as an objective lens. A ratio of over 95% means that the lens’
performance in general observations is comparable to that of an
aplanatic lens (which is corrected for spherical aberrations and
coma).
Note) A laser interferometer is used for actual assessment of
optical performance, so assessment is done at a single
wavelength. Unless otherwise noted, Strehl ratio measurements
are at the e-line (544nm).
