480FDL50 50 x 50 mm Longpass Dichroic Filter 480nm
The 480FDL50 is a Dichroic Filter, specifically a Longpass Filter with a 480nm cut-on wavelength, sourced from Knight Optical. This filter is designed for use in optical systems that require the separation or blocking of specific wavelengths of light.
The filter is rectangular in shape, with a width and length of 50mm each, and a thickness of 1.1mm. It is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high chemical durability.
The 480FDL50 features a coating on both the front and back surfaces, identified as 'kni 480fdl-0'. This coating is designed to provide the specified longpass characteristics, allowing light with a wavelength of 480nm or longer to pass through the filter while blocking lighter wavelengths.
The physical data of the filter indicates a cut-on wavelength of 480nm and a cut-off wavelength of 0nm. This means that the filter starts transmitting light at 480nm and continues to transmit all longer wavelengths.
Knight Optical, the vendor, lists this item as in stock on their website, with a catalog number of 480FDL50. The web link provided is valid, directing to a page with more information and the option to purchase.
