IR Bandpass Filters Vacation In Harsh Locales

Exploiting a single substrate dielectric construction for easy maintenance and durability, the company’s latest infrared (IR) OD 4 bandpass filters have a diameter of 25 mm and provide center wavelengths of 2.7 to 5.3 μm. The filters feature greater than OD4 blocking with center wavelengths optimized for analyzing water vapor, ethanol, formaldehyde, CO2, CO, and NO. Target applications include clinical chemistry, environmental testing, elemental and laser line separation, fluorescence, and immunoassays. EDMUND OPTICS INC., Barrington, NJ. (800) 363-1992.
