Infrared (IR) OD 4 bandpass filters

Edmund Optics has introduced its Infrared (IR) OD 4 bandpass filters, which provide the high transmission and deep rejection necessary to isolate narrow spectral regions for use in a wide variety of applications.

Infrared (IR) OD 4 bandpass filters take advantage of a single substrate dielectric construction, which ensures carefree maintenance and allows these durable filters to be used in harsh environments. These IR bandpass interference filters have a diameter of 25mm and provide center wavelengths of 2.7-5.3μm. They are ideal for use in environmental monitoring, security and Flir applications, and are especially suited for gas analysis.

Bandpass interference filters are excellent for use in a variety of biotech, biomedical and quantitative chemical applications. They selectively transmit a narrow range of wavelengths while blocking out all other wavelengths. Interference filters are perfect for use in instrumentation, and for a wide variety of applications, including clinical chemistry, environmental testing, elemental and laser line separation, fluorescence, and immunoassays. These IR bandpass filters feature >OD4 blocking with centre wavelengths optimised for analysing water vapour, ethanol, formaldehyde, CO2, CO and NO.
