87-859 12.5 mm Dia. Hard Coated OD 4.0 50nm Bandpass Filter; t=3.5 mm 1600nm
The 87-859 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 87-859 Bandpass Filter has a cut-on wavelength of 1575 nm and a cut-off wavelength of 1625 nm, with a central wavelength (CWL) of 1600 nm. This means it is designed to pass light most efficiently at the 1600 nm wavelength. The terms 'cut-on' and 'cut-off' refer to the wavelengths at which the filter begins and stops transmitting light, respectively.
The filter is hard coated on both the front and back sides with the EDm 87-859 coating. This coating enhances the filter's durability and performance. The filter's shape is that of a thin lens, which is often used in optical systems to reduce weight and thickness.
The 87-859 Bandpass Filter is currently in stock and available for purchase through the Edmund Optics website. The item's catalog number is 87-859, and it can be found at the following link: https://www.edmundoptics.com/p/1600nm-cwl-125mm-dia-hard-coated-od-4-50nm-bandpass-filter/30150/.
