65-795 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 1650nm
The 65-795 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically centered at 1650nm, with a full-width half-maximum (FWHM) of 12nm, making it ideal for applications that require narrowband transmission in the near-infrared spectrum.
The filter is constructed with a base shape of a circle, and it has a thickness of 7.5mm. It is made from UVFS Mal-1965 material, which is known for its excellent optical properties in the near-infrared region. The filter is coated on both sides with EDM 65-781 coating, providing superior protection and performance.
The 65-795 filter has a cut-on wavelength of 1644nm and a cut-off wavelength of 1656nm, ensuring a tight bandpass performance. The central wavelength (CWL) of the filter is 1650nm, providing a narrow and precise transmission window.
The filter is designed in a thin lens shape, making it compatible with various optical systems. It is currently in stock and available for immediate shipping. For more information, you can visit the product page at https://www.edmundoptics.com/p/1650nm-cwl-12nm-fwhm-25mm-mounted-diameter/20313/.
