Economy Red Cross Projecting Laser Alignment
Product Review (submitted on April 18, 2015):
50mW 650nm red cross laser alignment is not the primary purchased order. But I got a refund and change my primary order of 635nm red cross laser alignment. When 635nm red cross laser output power is higher than 50mW, the laser beam will not be very stable and even straight. At the end of 635nm red laser laser, there might be tiny tails. It might affect the cross measuring result. Thus I am suggested to choose this 650nm 50mW red laser alignment to finished my test.
When I user this 650nm 50mW red cross laser alignment in my cross positioning test, the cross lines are always very stable, straight and bright. The laser beam quality is quite excellent, and I am quite satisfied with this purchase change. It is performing wonderful.
