FB490-10 Dia:1 in Bandpass Filter; CWL=490 +-2nm; FWHM=10 +-2nm

The FB490-10 is a Bandpass Filter from Thorlabs, designed with a circular base shape and made from soda lime ru clear material. This filter is part of Thorlabs' extensive catalog, which includes a wide variety of optical elements from different vendors worldwide.

The filter has a diameter of 1 inch (25.4 mm) and a thickness of 3.5 mm, making it suitable for a range of optical applications. The FB490-10 is designed to transmit light in the center wavelength (CWL) of 490 nm, with a full width at half maximum (FWHM) of 10 nm. This specificity in wavelength transmission makes it ideal for applications that require precise light filtering.

The FB490-10's coating is another notable feature. Both the front and back of the filter are coated with "tho fb490-10", a coating that enhances the filter's performance and durability. The filter's shape is that of a Thin Lens, further expanding its potential applications in optical systems.

According to the provided data, the filter's cut-on wavelength is 485 nm, and the cut-off wavelength is 495 nm. This means that the filter allows light transmission between these two wavelengths, effectively blocking light outside this range.
