Why Is IR (Infrared) Laser Light Bad?
Lasers produce light in a quite sophisticated way that allows for specification of actual laser light frequency color. But within that realm of visible light, there lies unseen dangers that can be potentially harmful to the human eye, and that danger is IR (Infrared) light. Even though this light is not actually visible, it still holds the ability to pass through the structure of the eye reaching the retina. The problem with IR light is that even at low output powers it is still possible for some small damage to be done. Also, because you can’t actually see this light without tools prevents even simple blinking as protection. Though this may seem like no concern of yours, improperly manufactured lasers can cause damage to your image receptors that may only become visible later on as eye cells potentially degenerate. Therefore, having a laser of the highest quality with proper safety in mind is critical to your protection and the ability to use your laser in the long term.
Because of the way in which most solid state lasers are produced, there is a need to incorporate an IR filter which blocks the dangerous light produced by the 808nm IR diodes used to produce green, red, and blue lasers. Due to the lack of proper training and the cost to produce IR certified lasers, most lasers out there do not incorporate this safety mechanism. Even though you may be unaware of this difference, it is still very possible to subject your eyes to excessive IR light whenever you are working with poorly designed laser pointers.
Your safety should be the #1 concern of the laser manufacturer and is with Think Lasers. Every laser is 100% No IR Certified Lasers and incorporate high grade IR laser filters into each unique laser pointer design. Take a look at the pinnacle of laser pointer technology anywhere.
