Request InfoEdmund Optics Inc.Infrared OD 4 bandpass filters that provide the high transmission and deep rejection necessary to isolate narrow spectral regions have been unveiled by Edmund Optics. They are durable, and their single-substrate dielectric construction ensures easy maintenance. The bandpass interference filters have a diameter of 25 mm and provide center wavelengths of 2.7 to 5.3 μm. They selectively transmit a narrow range of wavelengths while blocking out all others. The filters feature >OD 4 blocking with center wavelengths optimized for analyzing water vapor, ethanol, formaldehyde, CO2, CO and NO....See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra May 2024 IssueJoulemeterThe IS50A-1KW-RMT from Gentec-EO is a high-power joulemeter for laser energy measurement up to 1 kW average power.
