IR-blocking filter holder for green laser by arpruss

Last crawled date: 4 years, 8 months ago

Cheap green laser pointers don't have an infrared filter and hence emit a lot of extra light in the infrared, which increases the danger of damage to eyesight. You can buy a cheap IR-cut filter on ebay or aliexpress and mount it on the end of your pointer with this holder. I suggest some drops of superglue to mount.
