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.

The Optosource is configured to produce intense focussed light for coupling either to the input slit of our monochromator, or directly into a light guide.
