87-838 50 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 1150nm

The 87-838 is a Bandpass Filter, specifically designed with a circular shape and a diameter of 50 mm. This filter is sourced from the reputable vendor, Edmund Optics, and boasts a thickness of 3.5 mm. The filter's primary function is to allow light transmission within a specific wavelength range while blocking light outside this range.

The 87-838 filter is designed to operate at a central wavelength (CWL) of 1150 nm, with a cut-on wavelength of 1137.5 nm and a cut-off wavelength of 1162.5 nm. This precise wavelength range is achieved through the application of advanced coating technology on both the front and back surfaces of the filter. The coating used is EDM 87-814, which is a hard coating that enhances the filter's durability and resistance to environmental factors.

This filter is classified under the category of "Filter" and sub-type "Bandpass Filter". It is made from UVFS MAL-1965 material, which is known for its excellent optical properties. The filter's geometry, including its diameter and thickness, is designed to ensure optimal performance in various optical systems.

The 87-838 filter is currently in stock and available for purchase through the Edmund Optics website. For more detailed information and specifications, please refer to the provided weblink.
