Lens mounting – standard and pre-mounted options
Note: ZnSe is a crystal material. Take great care when handling, mounting and cleaning these lenses.
Apply uniform pressure when handling or mounting ZnSe lenses. Do not use tools, including
tweezers, because the substrate easily scratches, cracks, or chips. Always wear latex or vinyl
finger cots or gloves when handling and cleaning these lenses to prevent contamination of the
substrate or coating. See appendix for MSDS information.
