FB1550-40 Dia:1 in Bandpass Filter; CWL=1550 +-8nm; FWHM=40 +-8nm
The FB1550-40 is a Bandpass Filter, part of the extensive catalog of optical elements offered by Thorlabs. This particular filter is designed with a circular base shape, made from soda lime ru clear material. The filter has a diameter of 1 inch (25.4 mm) and a thickness of 3.5 mm, making it a compact yet effective optical component.
The FB1550-40 operates at a central wavelength (CWL) of 1550 nm, with a full width at half maximum (FWHM) of 40 nm. The cut-on wavelength is 1530 nm, and the cut-off wavelength is 1570 nm, providing a narrow bandwidth for specific wavelength selection.
The filter's coating is consistent on both the front and back, with a coating identified as 'tho fb1550-40'. This coating enhances the filter's performance and durability. The filter's shape is described as 'Thin Lens', suggesting it may have lens-like properties or be used in conjunction with lenses in optical systems.
According to the vendor's information, the filter is currently in stock and the web link provided is valid. This filter is a reliable choice for applications that require precise wavelength selection in the 1550 nm range.
