ANTGLASS supplies and processes Zinc Selenide (ZnSe) Optical Material for optical, electronic, laboratory and industrial components made to customer drawings.
Material Overview
Zinc Selenide ZnSe: CVD infrared optical material. The material system is described as CVD infrared optical material. Selection begins with the exact grade, wavelength or optical function, thermal and chemical environment, starting form, finished geometry and inspection method. The material record is kept separate from the finished-part drawing so that grade data and manufacturing requirements remain traceable.
Applications associated with this material include CO2 lasers, MWIR/LWIR imaging, broadband IR windows. ANTGLASS uses the approved material and drawing to manufacture blanks and finished parts rather than treating a published material property as a universal component guarantee.

Design Rules for a Manufacturable RFQ
- Define the wavelength band, crystal orientation where relevant, coating and environmental exposure.
- Dimension critical surfaces, edges, holes, slots and datums separately on the drawing.
- Identify optical, sealing, bonding, coated and cosmetic zones before quotation.
- Match inspection methods to the functional tolerance and surface requirement.
- State prototype and production quantities together with cleaning and packaging needs.
Quality Risks and Inspection
Specialty optical materials can be soft, brittle, anisotropic, moisture-sensitive or temperature-sensitive. Use a material-specific machining, coating, cleaning and mounting design.
- Material identity and source documentation
- Dimensions, thickness and feature position
- Clear aperture, scratch-dig or cosmetic zone and transmitted-light inspection
- Edge chips, cracks and surface condition
- Cleaning, orientation and protective packaging
Applications and Product Connections
- CO2 lasers
- MWIR/LWIR imaging
- broadband IR windows
Material Comparison and Alternatives
Compare Zinc Selenide (ZnSe) Optical Material with Fused silica for UV-visible, sapphire for harsh windows, chalcogenide glass for molded IR optics.. Substitution should preserve the functional wavelength, refractive or spectral behavior, thermal expansion, temperature range, chemical durability, mechanical behavior, starting form and component cost.
