87-786 12.5 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 975nm
The 87-786 is a Bandpass Filter, specifically designed by Edmund Optics with a diameter of 12.5 mm and a thickness of 3.5 mm. This filter is made of UVFS Mal-1965 material, which is known for its excellent optical properties. The filter is hard coated on both the front and back surfaces with the coating code "edm 87-786".
The Bandpass Filter is designed to transmit light within a specific range of wavelengths while blocking light outside this range. The 87-786 model is designed for a central wavelength (CWL) of 975nm, with a cut-on wavelength of 962.5nm and a cut-off wavelength of 987.5nm. This makes it ideal for applications that require the precise filtering of light in the near-infrared spectrum.
The filter is shaped as a thin lens, which is beneficial for applications that require a compact optical design. The catalog number for this item is 87-786, and it can be found on the Edmund Optics website, where it is currently in stock.
