    Prism Optics

    I've been looking for some prisms for my lasers and I'm seeing that they come with coatings, different materials and tolerances. I'm not doing any kind of official lab work this is just a fun hobby. I would like to setup a couple prisms, mirrors, etc. Just to move the beam around the table /...

    Infrared from 445nM

    Would you mind sharing a picture of your lab setup? Ive seen a few laser tables but not sure where to start or how to safely terminate the beam.

    Infrared from 445nM

    I see you have many lasers. What do you use them for? I bought mine and while it’s absolutely amazing, it’s incredibly powerful and I can’t fathom a practical use for it.

That is where my concern begins. Do I need to buy the wave length blocking glass and get an IR testing card or...

    Does the 445 look violet to human eye or just camera?

    "thin blue line" laser used in memorial for fallen officers

    Its pretty cool I drive by it from time to time. It's not as bright as I expected. From Interstate 4 my 35 dollar "200mw" can sit next to the blue dot and looks much brighter.

    Cheap China Lasers Houdini

    I haven't been in the market for a laser in many months now. I bought a cheap China laser a while ago and liked it a lot for the price. 532nM supposedly 200Mw for $35.00. I was looking for other wavelengths for around the same price and spec. I purchased from T-mart since 35 bucks wasn't a make...

    Anyone bought from Tmart?

    So I learned how to focus the laser better and the matches do not have to be markered black and they only take a few seconds to light. This thing is becoming more and more impressive.
