BARRINGTON, N.J., Sept. 18, 2015 — Edmund Optics Inc. has announced a new line of TECHSPEC imaging filters for machine vision and imaging applications. The devices block UV, visible or IR wavelengths, and provide wide angles of incidence. They exhibit high and flat transmission profiles for even illumination. Optimized for use with popular LEDs, the RoHS-compliant filters feature an optical density >3. The filters are manufactured using an ion-beam sputtering technique, providing blocking of unwanted light. Thirty models are available in multiple mounting sizes and threads. Center wavelengths of 470, 524, 548, 634, 660 and 880 nm are available with transmission up to 97 percent. Light and dark red, green, blue, UV/VIS cutoff, and UV/IR cutoff models are available.
