Laser Scanning Confocal Microscopy
The LSCM is primarily used for imaging fluorescent samples. Organelles and proteins in cells or
tissues are imaged using native fluorescence or by adding fluorescent tags. The LSCM is based on
point scanning approach to image formation whereby the information for each pixel is obtained
sequentially instead of the broad area excitation approach used for widefield imaging. A laser is used
for selective excitation of a fluorophore and an optical bandpass filter limits the light reaching the
detector. The LSCM is useful for three-dimensional reconstruction of data. Spatial resolution ~
300 nanometers is achievable with objectives of numerical aperture of 1.3. The Zeiss LSM 410 was
upgraded by LSM Technologies (optics, detectors, and computer). The instrument is on a floating
optical table to minimize vibration transfer.
“LASER SCANNING CONFOCAL
MICROSCOPE:
A light microscope that allows imaging of
fluorescent structures in thick (tens to hundreds
of micrometres) specimens. A series of optical
'slices' are collected using a scanning laser beam
and specially designed optics to eliminate out-offocus excited fluorescence. The slices are
reconstructed to provide detailed threedimensional representations of the image data. ”

Two-Photon Excitation Microscopy
Two-photon excitation microscopy is best at reducing out-of-focus excitation thereby reducing the
risk of bleaching a volume of the sample which has yet to be imaged. The two-photon process
requires high photon density which is achievable at the focus point of the objective with ultra-short
light pulses. In some cases two-photon excitation can reduce photo-toxicity, improving live cell
imaging. The longer wavelength range required for the technique can make it possible to image
thicker sample compared to excitation in the ultraviolet and visible ranges.
Current capabilities
The two-photon excitation microscope is an upgraded feature of the LSM410. It requires the use of
the ultra-fast Mira laser in femtosecond mode as a light source.
- Excitation wavelength from 700 to 100 nm.

Fluorescence Lifetime Imaging Microscopy
FLIM is the measurement of the lifetime of a fluorophore in an excited electronic state as a function
of position on an image. This gives a picture of environment of the fluorophore. The lifetime of a
fluorophore can change with chemical composition (pH, calcium concentration) or because of
quenching (FRET, oxygen).
At the SSSC, FLIM is based on the time domain acquisition of information in conjunction with the
laser scanning confocal microscope. The pulsed laser system can used in pico- or femtosecond
mode with a variety of repetition rates, and it can be used in the visible or infrared regions.

Fluorescence Up-Conversion
The SSSC fluorescence up-conversion system is used to measure the lifetime of short-lived
fluorescent molecules in solution. The sample solution is exposed to an ultra-short laser pulse (400
nm) and the fluorescence emitted is monitored for intensity my mixing (up-conversion) it in a nonlinear crystal with another ultra-short laser pulse (800 nm), the probe. By delaying the time at which
the probe pulse reaches the non-linear crystal, and mixes with the fluorescence, the intensity of the
up-conversion can be monitored as a function of decay time. The up-conversion process is the sum
frequency generated in the non-linear crystal by the combination of the fluorescence and the 800 nm
probe light resulting in a wavelength shorter than that of the fluorescence. Lifetimes in the subnanosecond range can be measured using this technique.
Current capabilities
- Sample excitation wavelength: 400nm
- Decay lifetime measurement
- Rise-time measurement
- Cross-correlation FHWM: ~ 200 femtoseconds
