NF633-25 Dia. 25 mm Notch Filter; CWL=633nm; FWHM=25nm

The NF633-25 is a notch filter with a diameter of 25 mm, designed for use in optical systems that require narrowband rejection of specific wavelengths. Manufactured by Thorlabs, a leading vendor in the field of optical components, this filter is part of their extensive catalog, and it is currently in stock, as indicated by its weblink status.

This filter is specifically designed for use at a central wavelength (CWL) of 633 nm, with a full width at half maximum (FWHM) of 25 nm. This means it is highly effective at blocking light in the immediate vicinity of 633 nm, while allowing light at other wavelengths to pass through. The filter is made from UVFS material, identified by the Mal-1965 material ID.

The NF633-25 has a circular base shape and a thickness of 3.5 mm. It features a thin lens shape and is coated on both the front and back with the THo NF633-25 coating. This coating is specifically designed to enhance the filter's performance at the specified CWL and FWHM.
