LaVision Ultramicroscope II
Dual side illumination light sheet fluorescence microscope Dual side illumination light sheet fluorescence microscopes (LSFM) also called Single/Selective Plane Imaging Microscopes (SPIM) provide high speed optical sectioning. This microscope includes a white light super continuum laser and two microscope tubes - one for macro objective lenses and one for infinity corrected objective lenses. Both tubes are combined with zoom optics, motorized filter wheels and a motorized tube lenses.This microscope is optimized for the imaging of large cleared samples, such as those processed for CLARITY. It uses an Olympus MVX-10 microscope with a zoom body and 2x lens. This set up provides cellular resolution for very large samples. We also have an ultramicroscope tube for standard objectives. With these lenses, we have subcellular resolution. This microscope also has the option of dual sided illumination. The white light laser (WLL) provides a broad range of excitation wavelengths for this system, potentially allowing us to excite fluorophores with unusual excitation wavelengths. Location: Beckman Institute Basement Room B111H.
• This SPIM can do dual sided illumination of
sample with second light sheet
• Each side uses Triple Sheet Optics for generating three laser sheets perpendicular to the direction of detection.
• Width, Rayleigh length, focus and thickness of the three light sheets can be set by software.
• Min. thickness: <4.5 μm @ 488 nm for one individual sheet
• Focus range: > ±5 mm from center position of the sample for all usable imaging solutions
• Optimized for lower magnifications with larger field of view.
• Good for imaging large cleared samples such as whole mouse brains.
• Also can be used for in vivo imaging at room temperature.
• Motorized X,Y, Z stage
