Torr Scientific offers a wide range of CVD diamond vacuum viewports in the Conflat® (CF), style. The CVD optics are manufactured by a chemical vapour deposition process. The optics are braze sealed into the flange.
CVD diamond viewports are the ultimate optical material for a range of applications due to their excellent broadband optical transmission. Ranging from ultraviolet all the way into the far infrared. There are 2 versions of the optic available, an optical version and an X-ray version. These differ by their transmission in the UV and visible ranges.
Our CVD diamond viewports are helium leak tested, cleaned and packed to UHV standards on site at Torr Scientific.
