Nikon iLAS2 TIRF/FRAP

Location: I24.U1.031 (moonstone building)

System description and specifications

Nikon Ti2E stand equipped with iLas2 (GATACA) 360° / Ring / Azimuthal TIRF module. This module is using a pair of fast galvanometers to be able to spin the laser in the back focal plane of the objective several times during a single exposure time. That way artifacts such as fringes or rings caused by laser interference patterns are averaged out.
