NF808-34 Dia. 25 mm Notch Filter; CWL=808nm; FWHM=34nm
The NF808-34 is a notch filter with a circular base shape, designed and manufactured by Thorlabs. This filter is specifically designed for use with a central wavelength (CWL) of 808nm, making it ideal for applications that require precise filtering within this wavelength range.
The filter has a diameter of 25 mm and a thickness of 3.5 mm, providing a robust and compact solution for your optical needs. The NF808-34 features a coating on both the front and back surfaces, with the front surface coated with 'tho nf808-34' and the back surface coated with the same. This coating enhances the filter's performance and durability.
The physical data of the filter includes a full width at half maximum (FWHM) of 34nm, which is the width of the notch at half its maximum depth. This specification is crucial in determining the filter's ability to reject unwanted wavelengths.
The NF808-34 is available from Thorlabs and is currently in stock, according to the vendor's website. The item data also provides a catalog number and a weblink for easy reference and ordering. This filter is a high-quality, reliable option for applications that require precise wavelength filtering.
