Blue-light Hazard is defined as the potential for a photochemical induced retinal injury resulting from radiation exposure at wavelengths primarily between 400 nm and 500 nm. The mechanisms for photochemical induced retinal injury are caused by the absorption of light by photoreceptors in the eye. Under normal conditions when light hits a photoreceptor, the cell…
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…
The laser beam is usually a mechanical printed circuit board that provides low voltage replacement methods such as milling or automatic circuit board cutting. However, UV lasers have the advantage that other lasers do not have, that is, they can limit thermal stress. This is because most UV laser systems operate in a low power…
Laser lighting is a laser as a light source, but not directly to the laser “on the road”, so I am afraid that titanium eyes are really going to be blind. Laser lighting visible light laser lighting and infrared laser lighting. Visible light blue laser pointer lighting, according to the principle is divided into the following two:…
Hi there, in order to make it easily for you to choose your favorite laser pointer , now I’m gonna share knowledge about laser pen . How a laser pointer work? Laser pointer becoming more and more popular in daily life, people use them in many occasions, it features long range straight spot and laser beam which has an outstanding performance, but…
