UV Lens

Features

An optical system that employs optical-grade quartz glass for imaging in the near-ultraviolet region
This lens is optimized for application in the inspection of minute surfaces

Used for detection of counterfeit banknotes; falsified documents and credit cards, surface inspection of circuit boards for soldering defects

■ High performance quartz glass, enabling the capture of sharp images in the near-ultraviolet region.
■ Extended wavelength range (230nm to 800nm), with peak performance at 365nm.
■ Compact design, ideal for integration into machine vision systems
■ Optimised for use with band pass filters and UV illumination to provide falsified documents detection
