FB660-10 Dia:1 in Bandpass Filter; CWL=660 +-2nm; FWHM=10 +-2nm

The FB660-10 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's primary function is to allow light within a specific range of wavelengths to pass through while blocking other wavelengths.

The FB660-10 is designed to pass light with a central wavelength (CWL) of 660 nm, with a full width at half maximum (FWHM) of 10 nm. This means it allows a range of wavelengths around 660 nm to pass through, with the intensity of the transmission being half of its maximum at 655 nm and 665 nm. This characteristic makes it ideal for applications that require narrow-band light filtering around the 660 nm wavelength.

The filter's coating, applied on both the front and back surfaces, is designated as 'tho fb660-10'. This coating plays a crucial role in the filter's performance, ensuring the specified wavelength range is transmitted while blocking others. The filter's shape is that of a thin lens, which may provide additional functionality depending on the specific application.
