87-833 25 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 1500nm
The 87-833 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow passband. Sourced from Edmund Optics, this filter features a circular shape with a diameter of 25 mm and a thickness of 3.5 mm. The filter's primary function is to allow light transmission within a specific range of wavelengths while blocking light outside this range.
The 87-833 filter is designed for a central wavelength (CWL) of 1500nm, with a cut-on wavelength of 1487.5nm and a cut-off wavelength of 1512.5nm. This precise wavelength range is achieved through the filter's unique construction, which includes a hard coating on both the front and back surfaces. The coating material used is UVFS Mal- 1965, which is known for its durability and high performance in optical applications.
This filter is part of the Thin Lens shape category, which means it is designed to minimize optical aberrations and distortions. This makes it an ideal choice for applications that require high-precision optical performance.
The filter is currently in stock and available for immediate purchase. For more information, including detailed specifications and purchasing options, please refer to the provided weblink.
