BARRINGTON, N.J., July 21, 2011 — Infrared OD 4 bandpass filters that provide the high transmission and deep rejection necessary to isolate narrow spectral regions for use in a variety of applications have been unveiled by Edmund Optics.
They are durable for use in harsh environments, 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 are suitable for use in environmental monitoring, security, gas analysis, biotech, biomedical, quantitative chemical and forward-looking infrared applications.
They selectively transmit a narrow range of wavelengths while blocking out all others. Interference filters can be used in instrumentation and for clinical chemistry, elemental and laser line separation, fluorescence and immunoassays.
The filters feature >OD 4 blocking with center wavelengths optimized for analyzing water vapor, ethanol, formaldehyde, CO2
, CO and NO. They are in stock and available for immediate delivery.
