600FDL12 12.5 mm Dia. Longpass Dichroic Filter 600nm

The 600FDL12 is a Dichroic Filter, specifically a Longpass Filter with a 600nm 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 circular in shape, with a diameter of 12.5mm and a thickness of 1.1mm, making it suitable for use in compact optical systems. The base material of the filter is N-BK7 Schott, a widely used optical glass known for its excellent optical properties and durability.

The 600FDL12 features a dichroic coating on both the front and back surfaces, identified as 'kni 600fdl-0'. This coating is designed to reflect or transmit light at specific wavelengths, depending on the orientation of the filter in the optical system. In this case, the filter is designed to pass wavelengths longer than 600nm and block or reflect shorter wavelengths.

The physical data of the filter indicates a cut-on wavelength of 600nm and a cut-off wavelength of 0nm. This means that the filter begins to transmit light at 600nm and continues to transmit all longer wavelengths. The filter does not have a specified cut-off wavelength, indicating that it will continue to transmit all wavelengths longer than 600nm.

The 600FDL12 is currently in stock and available for purchase from Knight Optical. More information, including pricing and availability, can be found on the Knight Optical website.
