HF108B (Evident)


High-Speed Ultra-thin 8 Position Filter Wheel for Evident/Olympus Microscopes

The HF108B high-speed filter wheel for Evident microscopes holds up to eight 32 mm filters and allows users to simply and quickly tailor illumination to suit specific applications. The HF108B is ideal for high-speed widefield fluorescence microscopy or integration into confocal or super-resolution instruments.

The clear 29 mm aperture makes the HF108B an optimal choice for FN26.5 Evident microscopes, and the ultra-thin wheel body enables it to be used alongside F-mount microscope cameras, unlike previous Prior filter wheels.

The HF108B offers a marked improvement in speed and durability compared to the previous HF108A model and an easy-to-use unthreaded filter clamping mechanism.

The filter wheel is easily controlled through Prior’s ProScan III controller and can be ordered as a standalone system. It is compatible with Evident's CellSens Dimension and ScanR software packages.
