FB770-10 Dia:1 in Bandpass Filter; CWL=770 +-2nm; FWHM=10 +-2nm

The FB770-10 is a Bandpass Filter with a circular base shape, manufactured by Thorlabs. This filter is designed to transmit light within a specific range of wavelengths while blocking other wavelengths, making it ideal for applications that require wavelength selectivity.

The filter has a catalog number of FB770-10 and is available directly from Thorlabs' website. The current status indicates that it is in stock, ensuring quick delivery for your optical system needs.

The FB770-10 has a diameter of 1 inch (25.4 mm) and a thickness of 3.5 mm, making it compatible with most optical systems. The cut-on wavelength is 765 nm, and the cut-off wavelength is 775 nm, with a central wavelength (CWL) of 770 nm. This precise wavelength selection is achieved through a front and back coating of "tho fb770-10", which is also applied to the thin lens shape of the filter.

The physical data of the filter, such as the cut-on and cut-off wavelengths, are subject to a tolerance of +-2 nm. This tolerance ensures that the filter performs consistently within specified parameters, providing reliable optical performance.
