ZnSe is a preferred material for lenses, windows, output couplers and beam expanders for its low absorptivity at infrared wavelengths and its visible transmissionZnSe PrismThe transmission range of Zinc Selenide ZnSe-CVD is 0.5 - 20 µm.ZnSe CVD used for high power CO2 laser optics at 10.6µm, for protective optics windows or optical elements in FLIR (forward looking infrared) thermal imaging equipment, optics for medical and industrial applications (optical plane parallel windows (plates, disks, blanks), wedged windows, optical meniscus, spherical and cylindrical lenses, prisms, resonator mirrors of CO2 laser).The refractive index is near 2.4. Zinc Selenide has a very low absorption coefficient and is used extensively for high power infrared laser optic. It is non-hygroscopic.Zinc Selenide (ZnSe) - transparent in wide spectral range from yellow (visible) to far IR. ZnSe material is a chemically inert, non-hygroscopic and highly pure product that is very effective in many optical applications due to its extremely low bulk losses, high resistance to thermal shock and stability in virtually all environments, easily machined.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. The material absorption is verified by CO2 laser vacuum calorimetry.American Photonics manufacturing process provides testing and we can manufacture to customers specifications.

It’s very easy to figure out the magnification of your microscope. Simply multiply the magnification of the eyepiece by the magnification of the objective lens.The magnification of both microscope eyepieces and objectives is almost always engraved on the barrel (objective) or top (eyepiece). Look for numbers like 10x, 12.5x, etc.
