65-677 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=7.5 mm 400nm
The 65-677 is a 25 mm diameter Bandpass Interference Filter, manufactured by Edmund Optics. This filter is designed with a thickness of 7.5 mm and features traditional coatings on both the front and back surfaces. The catalog number for this item is 65-677, and it can be found on the Edmund Optics website, where it is currently in stock.
This filter is specifically designed for use with a center wavelength (CWL) of 400nm, providing excellent performance in this region. The cut-on wavelength is 395nm, and the cut-off wavelength is 405nm, ensuring a narrow bandwidth and high transmission. The filter's thin lens shape makes it ideal for use in a variety of optical systems.
The 65-677 filter is made from UVFS Mal-1965 material, which is known for its durability and optical quality. The filter's circular shape and thin lens design make it easy to integrate into existing optical systems. The front and back coatings, both EDMP 65-617, further enhance the filter's performance, providing excellent transmission and blocking unwanted wavelengths.
