65-731 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5mm 1064nm
The 65-731 is a 25 mm diameter mounted bandpass interference filter, specifically designed for use at a central wavelength of 1064 nm. This filter, offered by Edmund Optics, boasts a full width at half maximum (FWHM) of 10 nm, making it ideal for applications that require narrowband filtering around the 1064 nm wavelength.
The filter is constructed with a circular geometry, featuring a thickness of 7.5 mm. This robust design ensures durability and stability during operation. The filter's material ID is UVFS Mal-1965, further attesting to its high-quality construction.
The 65-731 filter's coating is another notable feature. Both the front and back surfaces are coated with EDM 65-671, a proprietary coating developed by Edmund Optics. This coating enhances the filter's performance and longevity, making it suitable for a wide range of applications.
The filter's physical data includes a cut-on wavelength of 1059 nm and a cut-off wavelength of 1069 nm. This narrow wavelength range ensures precise filtering, minimizing unwanted spectral leakage. The filter's shape is that of a thin lens, further contributing to its versatility and ease of use.
