ZnSe is a chemically inert, non-hygroscopic and highly pure material that very effective in many optical application due to its extremely low bulk losses, high resistance to thermal shock and stability in virtually all environments, easily machined. Transmitting in the range 0.5µm~19µm and having a very low absorption of energy makes it useful for optical components in high power laser window and multispectral applications, providing good imaging characteristics.

Applications:

ZnSe is one of the materials of choice for CO2 laser optics operating at 10.6 microns,  it is also widely used for IR components, windows and lenses, optical beamsplitters  and combiners, and for spectroscopic ATR prisms, high resolution thermal imaging systems.

Application case:

ZnSe: φ12.7x2mm, S1/S2: AR@594-633nm&10.6-11.1um, (Ravg<1.5%@594-633nm, Ravg<1.5%@10.6-11.1um)

ZnSe: φ22x3mm, S1/S2: AR@10.2-10.8um, (R<1%@10.2-10.8um)

ZnSe: φ16x2mm, S1/S2: AR@635-650nm&10.6um

ZnSe: φ20x3mm, S1/S2: HR@&633-650nm&AR@10.6um
