OptoSource illuminator

• Designed to work with Optoscan
• Solar emulator
• Fluorescence microscopy

Product Description

Cairn xenon and mercury/xenon mixed-gas arc light sources offer ultra-high stability, high intensity illumination. The extreme point intensity and broad spectrum make them particularly suitable for fluorescence microscopy, but the modular design and wide range of couplings ensures that they can be equally effective for other purposes.

Available in two basic configurations, the original Classic and the higher output Optosource, both models are configured to produce intense focussed light for coupling either to the input slit of a monochromator, or directly into a light guide. Derivations of the basic design include versions with parabolic reflectors for producing a collimated output beam and auxiliary condenser lens optics to aid uniformity.
