I know the 5mw thing, however I doubt that 5mw is totally safe but 6mw suddenly causes severe retinal damage. For a greenish wavelength region laser what mw would most likely not cause permanent damage assuming that: 1. The beam did not hit anyones eyes directly but assuming a highly reflective...

I mean one page with info on most of the popular laser diodes with a basic data sheet with output power, input voltage and current, wavelength at recommended current, dimensions, and other useful info. Pictures with different lenses of both the beam focused to infinity and of the laser dot...

Will be a m462 dpss laser diode. I noticed that they seem to range from 8$ to around 50$. I'm fine with paying more but if they are all the same then I would rather save money. Also what would be the safety margin (e.g. 5 sec of direct eye contact through glasses before possibility of damage)?

Im working on a project (still in the 3d modeling phase) where I will have a 25x30mm diameter heatsink, however it will not have any airflow (the entire thing, heat radiating tines and all, will be enclosed in a plastic cylinder not allowing for great heat transfer. As a protection, both for the...

... thinking back its a shame I don't live in hawaii anymore so I could say "Hi from HI"... Im very new to laser pointers, particularly high powered ones. The extent of my experience is a number of really, really, really crappy walmart ones and a 10 pack of terrible, but still fun to mess...

I reciently saw the phaser someone made that used a blueray diode. Looked nice but I would like to make my own in a bit different way. #1 im using 3d printed parts, #2 I will add in 2 weak 5mw laser diodes (one wide beam) and one just standard non dangerous dot laser. For the primary burning...
