How does Confocal
Microscopy work?
Laser Confocal
Microscopy uses lasers
to fluoresce samples,
which allows features of
the sample to be seen
better.
1. A laser beam is
passed through a light
source aperture.
2. The beam is
focused by an objective lens, onto a very small part of the
specimen.
3. The laser energy excited the sample, and causes it to
fluoresce.
4. Fluorescent light and the reflected laser light then is recollected by the objective lens, and the mirror splits the
beams and sends them to the detector. This signal is collected
by a computer.
5. Since the beam is only focused on a very small point of the
sample at one time, steps 1-4 are repeated many times, until
the entire sample has been scanned.
6. The computer program takes all of the images and creates a
rasterized image, and displas it on the screen.

How does an AFM work?
AFMs operate by measuring force between a probe and the sample. Normally, the probe
is a sharp tip. To acquire the image resolution, AFMs measure the vertical and lateral
deflections of the cantilever by using the optical lever. The optical lever reflects a laser
beam off the cantilever. The reflected laser beam strikes a position-sensitive photodetector consisting of four-segment photo-detector. The differences between the
segments of photo-detector of signals indicate the position of the laser spot on the
detector and the angular deflections of the cantilever
In contact mode, AFMs use feedback to regulate the force on the sample. The AFM
regulates and measures the force on the sample, which allows acquisition of images at
very low forces.
The feedback loop consists of the tube scanner, which controls the height of the tip; the
cantilever and optical lever, which measures the local height of the sample; and a
feedback circuit that attempts to keep the cantilever deflection constant by adjusting the
voltage applied to the scanner.

For Imaging
A beam of electrons is produced at the top of the microscope by an electron gun.
The electron beam follows a vertical path through the microscope, which is held
within a vacuum. The beam travels through electromagnetic fields and lenses,
which focus the beam down toward the sample. Once the beam hits the sample,
electrons and X-rays are ejected from the sample.
Detectors collect these X-rays, backscattered electrons, and secondary electrons
and convert them into a signal that is sent to a screen similar to a television
screen. This produces the final image.

For EDS Analysis
Detectors pick up the X-Rays that are emitted, and generates a spectrum from the
entire scan area of the SEM.
The Y-axis shows the counts (number of Xrays received and processed by the
detector) and the X-axis shows the energy level of those counts

How it works
A diamond stylus is moved vertically in contact with a sample and then
moved laterally across the sample for a specified distance and specified contact
force. The profilometer measures small surface variations in vertical stylus
displacement as a function of position. A typical profilometer can measure
features ranging in height from 10 nm to 1 mm. The height position of the
diamond stylus generates an analog signal, which is converted into a digital
signal that is stored, analyzed and displayed. The radius of diamond stylus
ranges from 20 nms to 50 μm, and the horizontal resolution is controlled by the
scan speed and data signal sampling rate.
For our experiment, we wanted to see if the lab’s sputter
coater coated a sample evenly. To do this, we coated a
glass slide with gold, made markings along the surface,
and used the profilometer to measure the thickness of the
gold from the outside edge of the slide to the center.

Results
What we found was that the thickness of the gold was greater near the edges of
the glass slide. As you moved further towards the center of the slide, the
thickness decreases at a rate of 3.7837 nm per mm.
