Low power direct semiconductor lasers are mainly used in plastic welding and soldering. In the plastic welding, laser welding with weld size precision, non-contact welding, mechanical stress, low thermal stress, welding appearance integrity, no welding slag and other advantages. In the solder, the laser welding with no welding head, non-contact, welding time is short and…
50 milliwatts is probably the maximum needed power for almost any laser pointing use. For seeing the laser “dot” on a wall or surface indoors or in dim light, 5 milliwatts of green is fine. The most demanding general-use pointing application is for pointing out objects in bright sunlight such as a daytime city architecture tour,…
The “Nominal Ocular Dazzle Distance” concept was developed by Dr. Craig Williamson and Dr. Leon McLin, around 2015. This concept allows more precision when determining how much a visible-light laser exposure interferes with vision by causing dazzle or glare. There are two main parts: 1. Determining how wide an area of vision can be blocked…
