CaF2 is perfect for any demanding purposes wherever its high damage threshold, reduced fluorescence, and superior homogeneity are valuable. It is actually preferred in excimer laser programs and regularly used in spectroscopy and cooled thermal imaging.
Cubic ZnSe is made by remedy of an aqueous Alternative of zinc sulfate with hydrogen selenide:[1]
You can e mail the internet site operator to let them know you had been blocked. You should involve Everything you had been executing when this webpage arrived up as well as the Cloudflare Ray ID found at The underside of the webpage.
Very good mechanical Homes:ZnSe has fantastic mechanical Homes, for example large hardness and toughness, making it well suited for use in programs where the windows could possibly be subject matter to significant stress or impact.
N-F2 is usually a RoHS compliant flint glass which has been engineered to get just about equivalent optical properties as F2 and provides outstanding performance inside the noticeable and NIR spectral ranges.
Sensitive to scratches: ZnSe is comparatively sensitive to scratches and various surface area defects, which may trigger scattering and absorption of light. This causes it to be vital that you handle ZnSe Home windows with treatment to stop damage.

Very low absorption coefficient:ZnSe provides a very low absorption coefficient, meaning that it does website not take in Significantly of The sunshine that passes as a result of it, which makes it perfect for use in large-electrical power laser methods.
It truly is powerful in several optical purposes owing to its superior resistance to thermal shock, stability in practically all environments and extremely small bulk losses.
The ability to regulate the beam diameter permits quick adaptation to distinct requirements. With optical filters, the beam expander to rework asymmetric beam distributions into a lot more uniform ones.
