565FDL12 12.5 mm Dia. Longpass Dichroic Filter 565nm

The 565FDL12 is a Dichroic Filter, specifically a Longpass Filter with a 565nm cut-on wavelength, sourced from Knight Optical. This filter is designed with a circular geometry, featuring a 12.5mm diameter and a thickness of 1.1mm. The material used for this filter is n-BK7 Schott, a well-regarded optical glass known for its excellent homogeneity and low auto-fluorescence.

The filter's primary function is to transmit light at wavelengths above 565nm while reflecting or absorbing wavelengths below this point. This makes it an ideal component for various optical systems that require the separation of specific wavelength ranges.

The coating on both the front and back surfaces of the filter is KNI 565FDL-0, which is specifically designed to enhance the filter's performance and durability. The filter's shape is that of a Thin Lens, which may provide additional functionality depending on the specific application.
