The Total Internal Reflectance Fluorescence (TIRF) microscope provides high signal-to-noise fluorescence imaging of a thin plane at the cell-coverslip interface. This microscope is equipped with filters for DAPI, GFP, Texas Red, and Cy5. It has two monochromatic EMCCD cameras that can be used for single color imaging or simultaneous two color imaging. It is equipped with the following laser excitation wavelengths: 405, 488, 561, and 640 nm.

The N-STORM (Stochastic Optical Reconstruction Microscopy) system uses a super resolution technique that images individual, blinking fluorophores over time and pinpoints the precise location of each fluorophore to reconstruct the image. It can achieve a lateral resolution limit of ~20 nm and axial resolution of ~50 nm. Multicolor imaging and 3D localization are possible with this microscope. This microscope is equipped with filters for DAPI, GFP, Texas Red, and Cy5. It uses a Hamamatsu sCMOS camera for high sensitivity detection of fluorophores. It is also equipped with the following laser excitation wavelengths: 405, 488, 561, and 640 nm.
