UV Bandpass filter applications

Schott UG UV bandpass filters are used on a range of applications. Applications such as fraud detection of bank notes use these meaning they can use a broad beam light source with a UG filter only allowing the necessary UV to pass.

The most commonly used is Schott UG1 but for deep UV applications UG5 will be better suited.

UV Bandpass filter coating options

  • Broadband Antireflective (BBAR) – Multilayer coating can be used for the UV further enhancing performance.

  • Wide angle broadband AR coating – When your filters need to work over extended angles of incidence
