Evident / Olympus IX83 TIRF



System description and specification

The Olympus cellTIRF-4Line system is an ultra-sensitive, simultaneous multicolor Total Internal Reflection (TIRF) microscope using four laser channels with independent beam paths. Individual motorized angle control for each laser ensures equal evanescent penetration (±1 nm), which enables the user to produce high-contrast images with minimal background noise for cell surface and single molecule studies.

Since the angle of each laser light source is independently motorized, their penetration depths can be synchronized across each wavelength using cellSens software. This also provides key data about the penetration depths that are possible with each laser/objective pair.
