Visitron Systems ORBITAL-100 Ring-TIRF laser illumination system

The ORBITAL-100 Ring-TIRF system for total internal reflection fluorescence, from Visitron Systems, is a compact unit based on high-speed 2D galvo that drives the Ring-TIRF illumination. The laser illumination system offers a large illuminated field of view to enable applications such as single-molecule tracking or STORM-based super-resolution microscopy.

Full 360° rotation by free circular diameter or elliptical trajectory at the back focal plane of the high aperture TIRF objective offers illumination with minimum interference fringes and shadowing effects. The system is suitable for TIRF and wide-field illumination applications, offering single or multimode fibre coupling. It offers 2D galvo controlled movement of the illumination spot for optimised point TIRF illumination. Oblique illumination is possible, as well as a combination with the flexible VS Laser Combiner with up to eight laser lines.
