87-844 50 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 1450nm

The 87-844 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow bandwidth transmission. Sourced from Edmund Optics, this filter features a circular shape with a diameter of 50 mm and a thickness of 3.5 mm, ensuring compatibility with a wide range of optical setups.

The filter is constructed from UVFS Mal-1965 material, a common choice for its excellent optical properties. It is designed to transmit light at a central wavelength (CWL) of 1450 nm, with a cut-on wavelength of 1437.5 nm and a cut-off wavelength of 1462.5 nm. This precise wavelength control makes it ideal for applications that require narrowband transmission.

The 87-844 is hard coated on both the front and back surfaces with EDM 87-820, a coating known for its durability and resistance to environmental factors. This coating ensures the filter maintains its performance over time, even in challenging conditions.

The filter's thin lens shape allows for easy integration into existing optical systems. It is currently in stock and available for immediate purchase, as indicated by its valid weblink status. For more information or to make a purchase, users can visit the provided weblink.
