This is the FF01-440/521/607/694/809-25 25 mm Dia. 440/521/607/694/809nm BrightLine penta-Band Bandpass Filter, a high-quality optical component sourced from Semrock. This filter is designed for use in a variety of applications that require precise wavelength selection.
The filter is a Bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking other wavelengths. The center wavelength (CWL) of this filter is 440nm, making it ideal for applications that require the use of blue light.
The filter has a circular geometry with a diameter of 25mm and a thickness of 2mm. It is made from UVFS Mal-1965 material, which is known for its excellent optical properties. The filter's coating is Sem FF01440521607694 on both the front and back surfaces, further enhancing its performance.
The physical data of the filter includes a cut-on wavelength of 415.05nm and a cut-off wavelength of 464.95nm. This means that the filter starts transmitting light at 415.05nm and stops transmitting at 464.95nm. The filter's shape is a Thin Lens, which is designed to minimize optical aberrations.
