87-809 50 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 925nm
The 87-809 is a Bandpass Filter, specifically designed by Edmund Optics with a diameter of 50 mm and a thickness of 3.5 mm. This filter is part of the UVFS MAL-1965 material ID family, which is renowned for its high-quality performance and durability.
The filter's primary function is to allow light within a specific wavelength range to pass through while blocking out other wavelengths. In this case, the Cut-On wavelength is 912.5 nm, and the Cut-Off wavelength is 937.5 nm, with the Central Wavelength at 925 nm. This makes it ideal for applications that require precise wavelength selection.
The 87-809 filter features hard coating on both the front and back surfaces, enhancing its durability and resistance to wear and tear. The coating, identified as EDM 87-785, is a high-quality coating known for its excellent performance and reliability.
The filter's shape is that of a Thin Lens, which is beneficial in applications where minimal optical path deviation is required. This filter is currently in stock and available for immediate purchase through the provided weblink.
