ISP Optics Zinc Selenide (ZnSe) Aspheric Lenses

ISP Optics Zinc Selenide (ZnSe) Aspheric Lenses are designed to provide small spot sizes across the entire wavelength range of 1 – 12µm. The zinc selenide (ZnSe) substrates provide low absorption and dispersion, as well as transmission from the visible to infrared spectra, allowing for the use of visible guide lasers. A broadband anti-reflection coating increases the transmission of these lenses across the entire 1 – 12µm, providing broadband performance for both infrared imaging applications and applications using multiple infrared laser lines. ISP Optics Zinc Selenide (ZnSe) Aspheric Lenses are ideal for use as scanning lenses in optical coherence tomography imaging (OCT) imaging systems, or as focusing lenses with fiber, CO₂, or MWIR laser sources.

Note: Special care should be taken when handling Zinc Selenide as it is a toxic material. Always wear rubber or plastic gloves to avoid risk of contamination.
