Product Description

Product Description

  350mw 420nm violet laser is direct diode, TEM00 lasers that offer the highest possible optical power and lowest noise available. The violet laser benefits greatly from the patented sealed optics module that ensures long term power stability and longer life diode operation. The short term power stability is enhanced through the use of the external photo-detector which is also protected from the outside environment by being inside the sealed optical module. The long term power stability is enhanced through the use of the sealed optics module ensuring that any contaminants that are generated from the electronics do not affect the optics. Life test data confirm over 10,000 hours of operation.
