The FB355-10 is a Bandpass Filter from Thorlabs, designed with a circular base shape and a diameter of 1 inch (25.4 mm). This filter is made of soda lime ru clear material and has a thickness of 3.5 mm. The filter is designed to have a central wavelength (CWL) of 355 nm, with a full width at half maximum (FWHM) of 10 nm.
The FB355-10 filter is coated on both the front and back sides with the THo FL355-10 coating. The coating on the front side is designed to cut on at 350 nm and cut off at 360 nm. This filter is available from Thorlabs and is currently in stock, according to the vendor's website.
This filter is suitable for applications that require narrowband filtering around the 355 nm wavelength. Its thin lens shape allows for easy integration into optical systems. The FB355-10 is a reliable and high-performance option for users seeking a bandpass filter in this wavelength range.
