Unlike the use of a simple laser pointer for temporary dot positioning work, a lot of engineers and factory workers would prefer to operate a Berlinlasers 405nm violet laser diode module for non destructive testing works. Being made with an import 405nm violet laser diode within 50mW to 500mW and cooling system inside a different dimension and metal housing tube, it enables high energy density violet laser light emission, and converts into a ultra clear and precise violet dot projection in continuous use.
Basically 405nm violet laser diode module projects quite special violet laser light source, besides its formal use for industrial machinery processing work, it is also making special use for fluorescent flaw detection, micro-crack detection, material purity analysis, coating thickness inspection. Unaffected by longer distance or higher lighting occasion, after its properly adjusted laser beam focus and dot emitting direction, it brings users excellent dot alignment experience for all industrial testing works conveniently.
