BARRINGTON, N.J., Aug. 16, 2016 — Edmund Optics Inc. has announced three new TECHSPEC Hard Coated Filters: High Performance OD 4 Shortpass Filters, High Performance OD 4 Longpass Filters and Imaging Filters. TECHSPEC High Performance OD 4 Shortpass Filters and Longpass Filters both feature a cut-off slope of <1 percent with a rejection of OD>4.0 and 91 percent transmission in the pass band. TECHSPEC Imaging Filters are designed to meet demanding machine vision and imaging applications. Optimized for use with popular LEDs, the imaging filters pass or block specific UV, visible, or IR wavelengths to provide very wide angles of incidence. The new lines join existing Hard Coated OD 4 Bandpass Filters with series at 10, 25 and 50 nm. The filters have the advantage of fabrication using hard coated plasma deposition technology, which ensures high performance and allows for exceptional durability. They provide high transmission of designated wavelengths and deep blocking of unwanted wavelengths, featuring maximum blocking within a few nm of the laser wavelength to isolate narrow spectral regions in a wide variety of applications.
