That's what I was guessing.just didn't want to burn em up. They're not expensive but took a while to arrive. Thank you. Pictures to come

i got 2 green and 2 blue last week. they all seem comparable. they have, what looks like the same housing. i got one from a different dealer with a different sticker and the host seems to have a slightly different thread pattern.i thought that was odd,but given its cheap chinese stuff it makes...

Thanks guys. EBay search it is.

My new problem is: the green module is bigger than the red.is this due to heat issues?I'm gonna have to go back to the original plan of separate drive and diode.grrrr

If I hit this thing with something higher than 200 mW will it fry it, or just not read? Id hate to burn it out with ir or something over spec. Also can I move this thread ?

Thanks guys.I don't plan to measure more than 200 mW for now. I'm sure the more I work with lasers the stronger I will want.I'm in college and don't have a lot of money. Where would a question like this go? I don't wanna keep screwing up. Thanks

Help! I'm looking at the laser bee hlpm 2 . $69 for a lpm seems cheap.I dont want to spend hundreds on a meter. Has anyone had experience with this unit?

I'm looking for green modules 5mw under 3/4 inch long. I've found a couple but they're all over $10 each. Is there cheap ones someplace? Thank you in advance for any help. Jim

I was thinking modules would be simpler. What is " head free" mean? For the price I think I need to buy a few anyway.

5mw 650nm laser diode 5 pack, AixiZ A link to the diodes I plan to use. I still need lens, and some sort of housing shorter than3/4 inch including lens.any input?

Hi everyone. I'm working on my first build.it includes (5) 5mW diodes and hopefully 1 driver.also I'm trying to configure the smallest lightest rechargeable power source. The reason for the single driver is this: the host isn't a metal case. Its plastic. And I'm trying to secure and protect the...

Ahhhh.very good to know.an assumption was made on my part about this.I thank you. I was just thinking that an ad here meant they were reputable.
