531FDN12 12.5 mm Dia. Bandblocking Dichroic Filter 531nm

The 531FDN12 is a Dichroic Filter, specifically designed for bandblocking applications, with a central wavelength of 531nm. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components. The filter is made from N-BK7 Schott, a widely used optical glass due to its excellent optical properties.

The filter has a circular geometry with a diameter of 12.5mm and a thickness of 1.1mm, making it suitable for a wide range of optical systems. The dichroic coating on both the front and back of the filter is 'kni 531fdn-0', which is specifically designed for this filter. This coating allows for efficient light transmission at the central wavelength while effectively blocking light in the specified range.

The 531FDN12 filter is designed to cut on at 600nm and cut off at 460nm. This means it begins to transmit light at 600nm and stops transmitting at 460nm, effectively blocking light in the region between these two wavelengths. The central wavelength of 531nm falls within this transmission region, ensuring optimal performance for its intended use.
