33-023 15.9 mm Dia. Deep UV Bandpass Filter 248.00nm

The 33-023 is a Deep UV Bandpass Filter, specifically designed with a diameter of 15.9 mm and a thickness of 1.5 mm. This filter is sourced from the reputable vendor, Edmund Optics, and boasts a catalog number of 33-023. The weblink provided leads to a valid page, indicating that the filter is currently in stock.

This filter is a Bandpass Filter, a type that allows light to pass within a certain range of wavelengths, while blocking other wavelengths. In this case, the 33-023 is designed to pass wavelengths of 248 nm, making it ideal for applications that require deep ultraviolet light.

The filter's physical data includes a cut-on wavelength of 238 nm and a cut-off wavelength of 258 nm. The cut-on wavelength is the shortest wavelength that the filter allows to pass, while the cut-off wavelength is the longest wavelength that the filter allows to pass. The central wavelength (CWL) of the filter is 248 nm, which is the wavelength at which the filter has its maximum transmittance.

The 33-023 features a coating on both the front and back surfaces. This coating, identified as 'edm 33-023', is designed to enhance the filter's performance and durability. The filter's shape is that of a Thin Lens, which is a lens with a thickness that is much smaller than its diameter. This shape contributes to the filter's compact design and ease of integration into various optical systems.
