Ideal to see surface of objects

Easy to see details of surface, objects and

scratches

Application examples of UV camera and lens

+ Surface inspection of circuits and soldering condition:

Clearer to detect damage, dust or stain

+ Manufacturing and quality control of semiconductors: Leaves no damage nor effect on the objects

+ Usages with microscope in medical applications

+ Detection of forgery, falsified documents, bills and credit cards:   *Genuine U.S. dollar bill does not emit light *Transparent stamp appears on latest credit card

+ Inspection of fiber optics

+ Inspection of oil contamination and leakage
