The 539FDN50 is a Bandblocking Dichroic Filter, measuring 50 x 50 mm, sourced from Knight Optical. This filter is designed to block light in the 462-615nm range while allowing light at the center wavelength (CWL) of 539nm to pass through.
The filter is made from N-BK7 Schott, a well-known optical glass, and has a thickness of 1.1mm. The rectangular shape of the filter is ideal for various optical applications. The coating on both the front and back surfaces of the filter is 'kni 539fdn-0', which contributes to its bandblocking properties.
The physical data of the filter includes a cut-on wavelength of 615nm and a cut-off wavelength of 462nm. This means that it begins to block light at 615nm and stops allowing light to pass at 462nm. The filter is currently in stock and available for immediate purchase through the vendor's website.
