625FDL12 12.5 mm Dia. Longpass Dichroic Filter 625nm

The 625FDL12 is a Dichroic Filter, specifically a Longpass Filter with a 625nm 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 base material of the filter is n-BK7 Schott, a well-regarded optical glass due to its excellent homogeneity, low auto-fluorescence, and high transmittance in the visible spectrum.

The 625FDL12 filter is coated with a kni 625fdl-0 coating on both the front and back surfaces, enhancing its performance and durability. This coating ensures the filter's efficiency in reflecting or transmitting light at specific wavelengths, making it suitable for various optical applications.

The filter's physical data indicates a cut-on wavelength of 625nm, meaning it starts to transmit light at this wavelength and above. The cut-off wavelength is 0nm, indicating that it transmits all wavelengths below 625nm. This characteristic makes the 625FDL12 a Longpass Filter, allowing it to separate or transmit longer wavelengths while blocking shorter ones.
