FB1550-30 Dia:1 in Bandpass Filter; CWL=1550 +-6nm; FWHM=30 +-6nm

The FB1550-30 is a Bandpass Filter from Thorlabs, a leading vendor in the optical industry. This filter, with a catalog number FB1550-30, is designed to operate at a central wavelength of 1550 nanometers, with a full width at half maximum (FWHM) of 30 +-6nm. The filter is circular in shape, with a diameter of 1 inch (25.4mm) and a thickness of 3.5mm, making it compatible with a wide range of optical systems.

The FB1550-30 filter is made of soda lime ru clear material, a common choice for its excellent optical properties and durability. The filter's coating, applied on both the front and back surfaces, is a proprietary design by Thorlabs, denoted as 'tho fb1550-30'. This coating enhances the filter's performance, ensuring precise wavelength selection and high transmission.

The filter's physical data includes a cut-on wavelength of 1535nm and a cut-off wavelength of 1565nm. This means that the filter begins to transmit light at 1535nm and stops transmitting at 1565nm, effectively passing light in the 1550nm range.
