The FB1590-12 is a Bandpass Filter from Thorlabs, a leading vendor in the optical industry. This filter, with a catalog number FB1590-12, is specifically designed for applications that require a narrow bandwidth of light around the central wavelength. The filter is circular in shape, with a diameter of 1 inch (25.4 mm) and a thickness of 3.5 mm, making it compatible with a wide range of optical systems.
The FB1590-12 filter is made of soda lime ru clear material, ensuring high transmittance and clarity. The bandpass characteristics of this filter are defined by a central wavelength (CWL) of 1590 nm, with a full width at half maximum (FWHM) of 12 nm. This means the filter allows light within a narrow range of wavelengths around 1590 nm to pass through, while blocking other wavelengths.
The filter's cut-on wavelength is 1584 nm, and the cut-off wavelength is 1596 nm. This ensures a tight control over the spectral range of the transmitted light. The front and back surfaces of the filter are coated with tho fb1590-12, a coating specifically designed for this type of filter. The filter's shape is that of a thin lens, which can be beneficial in certain optical system configurations.
