M48 – LSM800 / Vertical

System Description

The M48 system (vertical microscope) is an inverted 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.

This system has been custom converted into a vertical configuration that facilitates imaging of plant seedlings in close to natural growth conditions (geotropism).
Implemented root tracking software allows following of the root-tip growth over time.

The system is running under ZEN Blue.
