87-855 12.5 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 1425nm
The 87-855 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 from UVFS Mal-1965 material, ensuring high-quality performance. The filter's primary function is to allow light within a specific range of wavelengths to pass through while blocking out other wavelengths.
The 87-855 Bandpass Filter has a cut-on wavelength of 1400 nm and a cut-off wavelength of 1450 nm, with a central wavelength (CWL) of 1425 nm. This means it is designed to pass light most efficiently at the 1425 nm wavelength. The filter's coating, both on the front and back, is Edmund Optics' specific coating (EDM 87-855), which enhances its performance and durability.
This filter is available in a Thin Lens shape, making it suitable for various optical applications. The catalog number for this item is 87-855, and it can be found on the Edmund Optics website with a status indicating it is in stock.
