87-782 12.5 mm Dia. Hard Coated OD 4.0 25nm Bandpass Filter; t=3.5 mm 775nm
The 87-782 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 engineered to transmit light within a specific range of wavelengths, while blocking other wavelengths, making it an essential component in various optical systems.
The 87-782 filter is designed to operate at a central wavelength (CWL) of 775nm, with a cut-on wavelength of 762.5nm and a cut-off wavelength of 787.5nm. This precise wavelength range is achieved through the use of advanced coating technology, which is applied to both the front and back surfaces of the filter. The coating used is EDM 87-782, which is hard coated for durability.
This filter is part of the UVFS MAL-1965 material ID family, which is known for its high-quality optical properties. The filter is shaped as a Thin Lens, which is a type of lens with a very small thickness compared to its diameter. This makes it ideal for use in compact optical systems where space is at a premium.
The 87-782 filter is currently in stock and available for purchase through the Edmund Optics website. The catalog number for this item is 87-782. For more information, please refer to the provided weblink.
