521FDN50 50 x 50 mm Bandblocking Dichroic Filter 521nm
The 521FDN50 is a high-quality Dichroic Filter, specifically designed for bandblocking applications, measuring 50 x 50 mm in size. This filter is sourced from the reputable vendor, Knight Optical, and is readily available for immediate use.
The filter is designed to block light in the 470-572nm range, while allowing light at the center wavelength (CWL) of 521nm to pass through. This makes it an ideal choice for applications where specific wavelengths need to be isolated or blocked.
The 521FDN50 is made from N-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. The filter has a thickness of 1.1mm, providing durability while maintaining minimal optical distortion.
The front and back surfaces of the filter are coated with the KNI 521FDN-0 coating, which enhances its bandblocking capabilities. The filter is shaped as a thin lens, allowing for easy integration into various optical systems.
