FF01-835/70-25 25 mm Dia. 835/70nm BrightLine Single-Band Bandpass Filter by Semrock
Semrock's FF01-835/70-25 is a Bandpass Filter, specifically designed with a circular shape and a diameter of 25 mm. This filter is made from the material ID UVFS Mal-1965, and has a thickness of 2 mm. The filter is designed to allow light with a center wavelength (CWL) of 835 nm to pass through while blocking light at other wavelengths.
The filter's physical data includes a cut-on wavelength of 800 nm and a cut-off wavelength of 870 nm. This means that it begins to transmit light at 800 nm and stops transmitting at 870 nm, making it ideal for applications that require narrow-band light filtering.
The FF01-835/70-25 features a Thin Lens shape and is coated with the same material on both the front and back surfaces. The coating on the front surface is Sem FF01-83570, and the coating on the back surface is also Sem FF01-83570. This coating helps to enhance the filter's performance and durability.
