The 65-694 is a 25 mm diameter mounted traditional coated bandpass interference filter, with a thickness of 7.5 mm, specifically designed for applications requiring a center wavelength of 500nm. This filter is sourced from the reputable vendor, Edmund Optics, and is available for purchase directly from their website.
The filter is characterized by its bandpass type, which allows it to transmit light within a specific range of wavelengths while blocking other wavelengths. This makes it ideal for applications where a narrow range of wavelengths needs to be isolated or emphasized. The 65-694 model, in particular, is designed with a cut-on wavelength of 495nm and a cut-off wavelength of 505nm, ensuring a tight 10nm full width at half maximum (FWHM) at the center wavelength of 500nm.
The filter is constructed with a circular shape and a thin lens design, making it compatible with a wide range of optical systems. It features a front and back coating of EDM 65-634, which enhances its performance and durability. The filter's physical data, including its catalog number, weblinks, and vendor information, are all readily available, ensuring easy integration into your optical design process.
