M38 – SP8 DIVE confocal (inverted) with multiphoton lasers and incubation

System Description

The M38 system is an inverted point laser scanning confocal microscope. 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. SP8 DIVE features a highly sensitive HyD (Hybride detector) detectors with a high quantum efficiency and low noise as compared to standard PMTs. The system is equipped with a motorized xyz-stage and a hardware autofocus device. M38 is fully programmable and therefore able to run multidimensional experiments including any combination of the following: multiple positions, multiple wavelengths, z-Stacks, time-lapse.

In addition to the classical single photon excitation the M38 is equipped with a multiphoton laser and a spectral, non descanned (NDD) 4 Tune detector. The NDD detector contains 3 HyDs and 1 PMT. The emission light is separated by a combination of variable dichroics and bandpass filters over the whole visible spectrum 380 – 800 nm.

The SP8 features AOBS instead of classical beam splitters, a resonant scanner for fast imaging and an incubator with the on stage CO2 incubation.
