FB540-10 Dia:1 in Bandpass Filter; CWL=540 +-2nm; FWHM=10 +-2nm

The FB540-10 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 FB540-10 is designed to pass light with a center wavelength (CWL) of 540 nm, with a full width at half maximum (FWHM) of 10 nm. This means it allows a range of wavelengths around 540 nm to pass through, with the intensity of the transmission being half its maximum at 535 nm and 545 nm. This characteristic makes it ideal for applications that require narrow-band filtering around the 540 nm wavelength.

The filter's coating, applied on both the front and back surfaces, is specifically designed for the FB540-10 model. This coating enhances the filter's performance, ensuring the specified wavelength range is transmitted while blocking other wavelengths. The filter's shape is that of a thin lens, which may provide additional functionality depending on the user's specific application.
