Request InfoIDEX Health & Science - Semrock Optical FiltersSemrock has added nine new wavelengths to its RazorEdge “E” grade line of ultrasteep long-wave pass edge filters, increasing its total number to 15. The filters are designed to provide deep blocking at the laser wavelength, then quickly transition to high transmission in less than 0.5% of the laser wavelength.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra April 2020 IssueGlass Color FiltersC-Mount Longpass Glass Color Filters from Edmund Optics Inc. are pre-mounted versions of the standard Longpass Glass Color Filters for simple integration into optical systems.

Therefore, it’s useful for almost anyone involved in the specification and purchase of optical components to have some familiarity with the typical performance characteristics, trade-offs and limitations of various coating types, as well as some knowledge of the capabilities of common thin-film production technologies. This article provides an objective overview of both these topics.What are thin-film coatings? The purpose of any optical thin-film coating is to modify the transmittance and reflectance properties of the substrate material to which they are applied. Most coatings...WHITEPAPERSPhotonics.com 1/31/2020Colored Glass as a Versatile and Economical Means for Optical FilteringColored glass filters find many uses in optical systems including imaging, laser, and industrial equipment.
