FBP01-640/14-12.5 12.5mm Dia. 640/14 nm Nanopede Single-Band Bandpass Filter

The FBP01-640/14-12.5 is a single-band bandpass filter developed by Semrock, a renowned vendor in the optical industry. This filter, with the catalog number FBP01-640/14-12.5, is specifically designed for use in systems that require precise wavelength selection.

The filter is of the bandpass type, which means it allows transmission of light within a specific range of wavelengths while blocking light outside this range. The central wavelength (CWL) of this filter is 640 nm, making it suitable for applications that operate within this wavelength range.

The filter is circular in shape, with a diameter of 12.5 mm, providing a reasonable balance between size and light-capturing capability. It is made from fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock.

The FBP01-640/14-12.5 has a thickness of 2 mm, which is typical for such filters. The cut-on wavelength is 633 nm, and the cut-off wavelength is 647 nm. This means that the filter starts transmitting at 633 nm and stops transmitting at 647 nm, effectively isolating the 640 nm wavelength.

The filter's coating is a crucial aspect of its performance. Both the front and back surfaces of the filter are coated with the Semrock FBP01-640 14 coating, which is specifically designed to enhance the filter's performance in the 640 nm wavelength range.

The filter's shape is thin lens, which suggests that it may have some light-focusing capabilities. However, this should be confirmed with the vendor or through experimental testing.
