Hi guys. So I went ahead and got the Thor M II blue 1.3W from eBay. The laser is here. Took only 3 days to arrive via DHL. I'm very happy with it so far. The casing looks all metal made, but I can't tell if the lens are glass, as promised, or acrylic. Is there a way to tell a glass lens from...

Hi guys, I'm about to buy this THOR from this guy: Thor M II 2 Laser Pointer 445nm 450nm Blue Laser Beam Burn Match Paper Military | eBay He also claims GLASS lens and METAL fixtures. We exhanged e-mails where he confirmed these claims. What do you guys think? Any experience with this...

Thank you all for your kind help! :) I'll research some more before buying my laser. I have two questions still, and forgive me if I'm steering off topic: - How important are glass vs acrylic lens? Does the acrylic have an habit of melting after prolonged use? - When a laser is "focusable"...

Hello to everyone on the forum. I'm about to buy my second power portable laser. I'm looking for a high-power blue laser - for use in burning, star-pointing, and to put on a show. 1W-2W may be overpowered, but I really want a burning laser. After some investigating around the forum I was left...

They are glued to the steel and super-glue can be tougher then iron if over a large surface. The lens screws in the frame to be near the laser diode. So near in fact I think at the max screwing the lens touch the laser diode's tip, or they'r just separated by an hairwidth. Even if I did manage...

That explains they'r price... I tried moving the original lens close to lens but since everything is mounted on a steel frame I'd have to unglue the lens from they'r support to move them closer to the source. I'm not going to try this, I'll fail and break the lens. I Do Not Want To Make The...

Thank you DTR. If I understood the post properly , these lens are special because they are Anti-reflective coated, am I right? Also, these lens are cylindrical because of the laser's beam rectangular shape? What happens if I use simple AR convex lens? Still I am confused about the size of...

Again I underline that I created this post to get help on what lens should I choose to fix my laser beam divergence. I do not really care at the moment about it's power, nor do I believe it's exact power is important in order to choose the appropriate optics. When I get the change to test my...

Yes, the power is over 1W up to 2W, I said 2W as it's top to make sure the lens you'd recommend can withstand the power. Even at low battery it can burn through black CD casing in 10sec. Of course "amount of burning power" is not a good way to measure power because it depends on the focusing...
