The FF01-630/69-25 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 boasts a thickness of 2 mm. The filter's primary function is to allow light transmission within a specific wavelength range, while blocking other wavelengths.
The FF01-630/69-25 is designed to permit light transmission at a central wavelength (CWL) of 630 nm. The cut-on wavelength is 595.5 nm, and the cut-off wavelength is 664.5 nm. This means that the filter will block or reject light outside of this range, enhancing the signal-to-noise ratio in your optical system.
The filter's coating is a crucial component of its design. Both the front and back surfaces of the filter are coated with the same coating, referred to as "sem ff01-63069". This coating is specifically designed to enhance the filter's performance and durability.
The filter's physical shape is that of a Thin Lens, which can be beneficial in certain optical system configurations.
