500FDL50 50 x 50 mm Longpass Dichroic Filter 500nm
The 500FDL50 is a Dichroic Filter, specifically a Longpass Filter with a 50 x 50 mm square shape, sourced from Knight Optical. This filter is designed to transmit light at wavelengths above 500nm while blocking or reflecting wavelengths below this point.
The filter is made from N-BK7 Schott, a popular optical glass due to its excellent homogeneity, low auto-fluorescence, and high damage threshold. The geometry of the filter includes a width of 50mm, a length of 50mm, and a thickness of 1.1mm, making it a thin and compact optical element.
The physical data of the filter indicates a cut-on wavelength of 500nm, meaning it starts to transmit light at this point, and a cut-off wavelength of 0nm, indicating it blocks all wavelengths below this point. The coating on both the front and back surfaces of the filter is KNI 500FDL-0.
This filter is currently in stock and available for immediate purchase from Knight Optical's website. The weblink provided leads directly to the product page for easy access and further information.
