575FDN12 12.5 mm Dia. Bandblocking Dichroic Filter 575nm
The 575FDN12 is a Dichroic Filter, specifically designed for bandblocking applications, with a diameter of 12.5 mm. This filter is sourced from Knight Optical, a reputable vendor known for its high-quality optical components. The filter is made of N-BK7 Schott, a widely used optical glass due to its excellent optical properties.
The filter's primary function is to block light in the 460-690 nm range while allowing light at the center wavelength (CWL) of 575 nm to pass through. This makes it ideal for applications that require the selective removal of specific wavelengths. The filter's thickness is 1.1 mm, providing a good balance between durability and light transmission.
The front and back surfaces of the filter are coated with KNI 575FDN-0, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by improving its durability and maintaining its optical properties over time. The filter's shape is that of a thin lens, ensuring minimal distortion and high optical quality.
The 575FDN12 is currently in stock and available for purchase on Knight Optical's website. For more information, please refer to the provided weblink.
