FF01-661/20-25 25 mm Dia. 661/20nm BrightLine Single-Band Bandpass Filter by Semrock
The FF01-661/20-25 is a Bandpass Filter, specifically designed with a circular shape and a diameter of 25 mm. This filter is sourced from the reputable vendor, Semrock, and is readily available for purchase through their online store. The item data indicates that it has a thickness of 3.5 mm, making it a suitable option for various optical applications.
The filter's primary function is to allow light transmission within a specific wavelength range while blocking light outside this range. The FF01-661/20-25 is designed to cut on at 651 nm and cut off at 671 nm, with a central wavelength (CWL) of 661 nm. This precise wavelength range makes it an ideal choice for applications that require narrow-band light transmission.
The filter's coating is another crucial aspect of its design. Both the front and back surfaces of the filter are coated with "sem ff01-66120", which is specifically designed to enhance the filter's performance and durability. The filter's shape is described as a Thin Lens, further enhancing its functionality in optical systems.
