The 67-838 is a 25 mm diameter mounted traditional coated bandpass interference filter, with a thickness of 5.9 mm, designed for applications requiring a narrow passband around the 700 nm wavelength. This filter is sourced from Edmund Optics, a leading vendor in the optical industry, and is available for purchase through their official website.
The filter is designed with a base shape of a circle, making it suitable for a wide range of optical systems. It is made from UVFS MAL-1965 material, ensuring high-quality performance and durability. The filter's geometry, including its 25 mm diameter and 5.9 mm thickness, is optimized for easy integration into various optical setups.
The 67-838 filter features a cut-on wavelength of 695 nm and a cut-off wavelength of 705 nm, resulting in a center wavelength (CWL) of 700 nm. This precise wavelength control makes it ideal for applications that require narrowband filtering around the 700 nm region.
The filter's front and back surfaces are coated with EDM 67-771, providing excellent optical performance and protection. The filter's shape is thin lens, further enhancing its compatibility with different optical systems.
