500FDL12 12.5 mm Dia. Longpass Dichroic Filter 500nm
The 500FDL12 is a Dichroic Filter, specifically a Longpass Filter with a 500nm cut-on wavelength, sourced from Knight Optical. This filter is designed with a circular geometry, having a diameter of 12.5mm and a thickness of 1.1mm, making it suitable for various optical applications.
The filter is made of N-BK7 Schott, a widely used optical glass due to its excellent optical properties and high chemical resistance. The filter's coating, kni 500fdl-0, is applied on both the front and back surfaces, contributing to its longpass filtering capabilities.
The 500FDL12's physical data indicates that it cuts on at 500nm and cuts off at 0nm. This means that it allows light at wavelengths greater than or equal to 500nm to pass through while blocking shorter wavelengths. This property makes it ideal for applications where the differentiation of longer wavelengths is required.
The filter is currently in stock and available for immediate purchase on Knight Optical's website. For more information, users can visit the provided weblink.
