Do you have any suggestions for prisms or lenses?

Ok, so any help with the kind of lens or whatever optics I need to focus it?

So I tried the 300mw IR and it focuses fine. That means the diode is just really weird I guess. :undecided:

Yes, I've put the lens closer and farther away from the diode and it only focuses a few cm away from the lens regarding the distance the lens is from the diode. I have a 300mw IR but I replaced it with the 1W cuz the 300mw was to weak. I'll try powering up my 300mw IR when I get the chance and...

Also, I'm using a driver that specs for 100-500mw diode. It will just keep the diode from going full power right? Would it have any other affect on the diode?

I have it in a module like this o-like one: 9mm diode housing w/glass lens for red laser or 808nm | eBay I tried using the lens it came with and this lens: 660nm/808nm Glass Collimating Lens/M9P0.5 Metal Frame | eBay The problem it not that it doesn't burn at a distance but that it doesn't...

Yea I have safety goggles for most of the wavelengths. Any ideas concerning the topic?

I just built a 1W 808nm IR laser. It works really well and burns nicely but only at about 5cm. No matter what distance I put the lens at it's focused only to one point. :confused: I tried 3 different lenses that I had but they all do the same thing. I've built a green, red and violet laser...

Thanks Dave, Yea, I noticed the driver and diode spec as well but since the diode is only $4 I bought another one. I didn't get to try it out yet, will be doing that soon. If it doesn't work I guess I'll just have to buy a different driver.

I have a 300mw 808nm laser diode w/driver and this lens: 660nm/808nm Glass Collimating Lens/M9P0.5 Metal Frame - eBay (item 260724564678 end time Jun-18-11 05:24:39 PDT) I looked at vids and pics and everyone has a pinkish dot but I have a dim red dot. do I need a special lens or something to...

Are these good? $30 Protection Glasses for 808nm~850nm Infrared Laser I might get them if I can't find anything cheaper.

I don't have goggles for it. I was thinking of getting some before starting the project but I looked on ebay and they're expensive. I got 405nm-532nm goggles for $20 but the lowest I found for 808nm was $40. Any place I can get a pair for cheap?

I really don't think there is a point in getting a 500mw for $22 when I can get a 1W for $12. If I put either one together with that driver I'll get the same amount of power out and maybe a bit more out of the 1W. But I'm thinking just for starters, since I've never built an 808nm, I'll get one...

I don't have the diode yet but I'm thinking of getting something like this: 808nm diode | eBay I need about 1.2A for max power so I guess it wont work. What would I need to build my own driver? I have a basic idea of how to do it but have never built one.

Will this 808nm driver work with a 808nm 1W diode. It says 100mw-500mw so I'm not sure. 808nm 100-500mw Laser Diode Driver Reverse Protection | eBay
