You may be able to do it. But you'd probably need a telescopic lens to expand the beam and then another lens closer to focus it again.

Hey everyone. We all love lasers here, we all know that. But how many of us get to work in a state-of-the-art laser research lab?! I do! A few days ago, I received an email from the physics adviser at my school (I'm a physics/math major) informing me (and other physics majors) of a new upper...

And note that it's just a CNI rebranded.

Oh. May not be the same one then. It looked awfully similar and I thought the model was the same :thinking:

I was eyeing that meter before I emailed the seller. It's not built for low power diodes. It's more accurate between 5-50W. I'd am surprised you got as good results as you did with the other lasers.

Truss... just so you're aware, you will be hated here if you try to profit from a group buy. Just be honest and tell us what the supplier told you and see if people are willing to pay that. If someone finds out you are charging as much as you can to make money....

Very neat! If I had the funds right now, I would use this for the 45A driver I need for my IR bar >.>

BShanahan is correct. However, do note that the ANGLE at which the light strikes the glass DOES affect the amount of reflected light. In particular, if the laser (collimated) is shined at glass at a large angle from the perpendicular, then substantially more will be reflected than if it were...

This was my first thread: http://laserpointerforums.com/f51/first-build-59823.html I have to say, Anselm was kinda a jerk to me =p My questions weren't too uninformed. I just had never seen a laser diode before, so I probably derped and destroyed some looking for them.

Re: Lots 'o diodes 520/450 GB Sign me up for a 635 too.

Re: Osram diodes 520/450 GB I wonder where the supplier got these for so cheap? I was even considering buying a pack of 20 of them myself, then binning/selling. Just so you're aware... this is entirely wrong =p 30mW 515nm are completely different diodes from 50mW 520nms. Please fix that in...

Re: Osram diodes 520/450 GB I'll take 3 515nm please :D

Ooo o.o I would want some! D:

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please God damnit. I gas staring at the Metrologic auction and watching Family Guy at the same time and didn't notice it end. Fail XD

Actually, the V4.1 will be available from DTR and Garoq soon. They both placed their orders, I am just waiting on the parts to arrive to begin manufacturing!

Welcome to the forum :D I suppose I will answer your questions. 1. It depends who you are buying from. A lot of the time, a "module" is just the laser diode and the AixiZ module it comes in (a small, easily handled barrel that you can stick a bare laser diode in). Other times, for instance...

I'm physics and mathematics.

Heh. Well, I dun have a roommate XD But this year, I plan on reflowing outside because I am afraid the smoke might set off my alarm :\

Heheheh. I brought my whole goddamn lab to my dorm (including my toaster ;) ).

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please If Metrologic ML810 Helium Neon Laser 105 125 Vac | eBay stays low, then I'm calling dibs =p A nice contained unit ^_^ EDIT: Although, actually, it's just a plug'n'play and the person said that he tested that...
