UV Quartz Lenses
If long-range UV-A (between 350 and 400 nm) suffices, so will some lenses.
If you want to record UV shorter than 350 nm, only quartz lenses will be satisfactory.

Most types of glass will allow long wave UV to pass but absorb all the other UV wavelengths, usually from about 350 nm and below. Only specially developed lenses made of quartz (fused silica) or quartz and fluoride can be used. Using these lenses allow the camera to reach the 180-200 nm range. Lenses based purely on quartz show a distinct focus shift between visible and UV light.

Sample Applications:
* Detection of fire, forgery, falsified documents and money inspection
* Inspection of oil contamination and/or leakage
* Manufacturing and quality control of semiconductors
