| Message: | Zinc Selenide (ZnSe) is a preferred material for lenses, windows, output couplers and beam expanders for its low absorptivity at infrared wavelengths and its visible transmission. For high-power applications, it’s critical that the material bulk absorption and internal defect structure be carefully controlled, that minimum-damage polishing technology be employed, and the highest quality optical thin-film coatings are used.
Typical Applications:
• CVD laser grade ZnSe and IR grade ZnSe.
• Greater than 90% transmission from 3-12μm.
• Low dispersion and low absorption.
• Ideal for thermal Imaging, FLIR, and medical systems.
• High performance, cost-effective ZnS fabrication.
• Adequate ZnSe substrates and blanks available. |
