M37 – LSM800 Axio Imager (upright)

System Description

The M37 system is an upright point laser scanning confocal microscope (LSM800) equipped with high-sensitive GaAsP (Gallium Arsenide, like LSM780 and 880) detectors and a transmitted light detector. It is a complete spectral system allowing the free choice of detection and the acquisition of lambda-stacks as well as subsequent unmixing for the separation of dyes with overlapping emission spectra. This system can be used to acquire 2 different fluorophores simultaneously. A variable secondary dichroic (VSD) allows the precise splitting of the emitted wavelengths into 2 channels. The system is running under ZEN Blue.
