M31 - Visiscope Spinning Disk Confocal with Incubation and FRAP unit

System Description

The M31 Visiscope Spinning Disc Confocal (Visitron SystemsGmbH, Puching, Germany) is based on a Nikon Eclipse Ti E inverted microscope, equipped with a Yokogawa W1 spinning disc (SD) allowing fast confocal acquisition. All components are controlled by the Visiview software. Visiview is Python-based and is fully scriptable.
The system is able to run multidimensional experiments including any combination of the following: multiple positions, multiple wavelengths, z-Stacks, time-lapse. This makes it suitable e.g. for various live cell experiments or the automatic acquisition of a large amount of images (screening).

The Nikon microscope stand is equipped with the TI-ND6-PFS Perfect Focus System, a reflection-based autofocus that keeps the focus from drifting over time, even in the presence of temperature shifts.
In addition to spinning disk acquisition, a FRAP-unit can be used for localized illumination via laser point scanning. This allows for FRAP and photoactivation experiments with fast spinning disk acquisition.
The system is adapted for slides, 30 mm dishes and well-plates (for plates, a special sample holder needs to be installed).

CAUTION: Labtek chambers cannot be used! Please substitute with Ibidi multiwall chambers.
