Request InfoMeller Optics Inc.Meller Optics Inc.'s Viewport Optics Preparation Service offers a two-step process: It provides a ground window blank -- usually fused silica or sapphire -- for customers to metallize, and it performs the final polishing. The result is a uniform window for assembly into viewports. The window's outside diameter can be from 1/4 to 3 in. and the thickness, from 2 to 10 mm in stepped- or straight-wall configurations. Surface finishes from 10 wavelengths to λ/10 and 60-40 scratch/dig are typical. The company also can work with ZnSe, ZnS, CaF2, MgF2 or other materials.See full productRelated content from Photonics MediaPRODUCTSPromoted Content November 2022 IssueSpecialty Fiber Fused Silica PreformsOptical fibers are among the hidden champions of our time.
