Infrared Filters

Infrared, or IR for short, is extremely dangerous because it is invisible to the human eye. Despite not being visible, IR rays can still pass through the anterior structures of the eye and reach the retina. Since you are unable to detect IR, there will not be any blink or aversion reflex to protect your eyes from damage. This damage can be done even for modest power lasers without any immediate symptoms. As the cells in your eyes do not regenerate, you must be careful not to damage your eyes.

DPSS 532nm green lasers are manufactured from 808nm IR diodes and from 1064nm IR lasers. An IR filter is required to block out excessive IR passing through the crystals. However, to lower costs and cut prices, numerous manufacturers do not equip their lasers with IR filters. Although you are unaware of its presence, your eyes may be subject to excessive IR when you are working with these poorly made lasers.

Because your safety is our first concern, SLOC products are 100% NO IR Certified and come equipped with a high grade IR filter.
