The FF01-860/11-25 is a Bandpass Filter, specifically designed for use in optical systems. This filter, sourced from the reputable vendor Semrock, is a Circular filter with a diameter of 25 mm and a thickness of 2 mm. The filter is made from UVFS Mal- 1965, a material known for its optical properties.
The filter's primary function is to allow light transmission within a specific wavelength range, while blocking other wavelengths. The FF01-860/11-25 is designed to allow transmission of light at 860 nm, with a cut-on wavelength of 854.5 nm and a cut-off wavelength of 865.5 nm. This precise wavelength selection is achieved through the application of a coating on both the front and back surfaces of the filter, specifically Sem FF01-86011.
The filter's geometry is shaped as a Thin Lens, which can be beneficial in certain optical system configurations. The physical data provided includes the cut-on and cut-off wavelengths, as well as the central wavelength (CWL) of 860 nm.
