67-856 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 890nm
The 67-856 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically centered at 890nm, with a full width at half maximum (FWHM) of 10nm, making it ideal for applications that require narrowband filtering in the near-infrared spectrum.
The filter is constructed with a base shape of a circle, and it features a thickness of 5.9mm. The material ID for this filter is UVFS MAL-1965, which provides excellent optical performance and durability.
The physical data of the filter includes a cut-on wavelength of 885nm and a cut-off wavelength of 895nm. The central wavelength (CWL) is 890nm, which is the primary wavelength that the filter is designed to transmit.
The filter is coated on both the front and back surfaces with EDM 67-789, a traditional coating that enhances its performance and durability. The shape of the filter is thin lens, which ensures easy integration into optical systems.
The filter is currently in stock and available for purchase through the Edmund Optics website. The weblink provided leads directly to the product page, where more information about the filter, including its specifications, applications, and pricing, can be found.
