Our workhorse upright confocal microscope is equipped with visible wavelength laser sources as well as a 2-photon fs laser (SpectraPhysics Tsunami, ~700-950 nm) for improved thick tissue imaging or activation of UV dyes; external non-descanned detectors can be used to collect a greater emission signal. System application modules include FRET, FRAP, spectral un-mixing. A prism-based detection system allows the user to select exact emission wavelengths, as well as to construct a spectrum-wide emission curve of fluorescence. System is equipped with an assortment of oil, immersion, water, and dry lenses.
