532nm 200mw laser

[BillyBob]

I was wondering if this laser was accurate. I have heard that Techhood was a reputable seller. Industrial 532nm 200mW Green Dot Laser Module | eBay

 

[Alaskan]

Ask him how much of that 200mw is infrared and if he will guarantee 200mw of 532nm green. I've always found him to be reputable, at least, far more so than most China sellers but he makes mistakes from time to time, always corrects them from what I've seen so far.

Alright will do, thanks for the help!

I bought two of these modules and they are 100mW including IR. sorry to bear bad news don't waste your money. They did send me a second one for free to make good but it's still not what I thought I was buying. Both Alaskan and I have looked extensively for true 200 mW modules but can't find any. O like will sell you one but that company is more trouble then they're worth IMO.

Way way back in the day, (5 years +) O-like offered a small size - 200mw module, they would hand pick a high power one for you and send (and I own one inside a Krypton Groove) like this:

100mW industrial green laser module [OLGLM100] - $40.00 : Zen Cart!, The Art of E-commerce

Now the only one I know of is this one

Industrial/DIY Real 200mW green laser module /long duty cycle [OL-GM-200] - $89.99 : Zen Cart!, The Art of E-commerce

Only guarantee is over 170mw per their site. I haven't seen a small module for a green DPSS approaching 200mw since. Heat and other issues, most are significantly larger. Techhood might have enough room for heatsinking in there, but as mentioned, power output isn't there.

And as mentioned, you might look at this thread first (YMMV):

Thanks for all the help! Guess I will keep looking for a true 200mw 532nm laser.

You can easily find them, just probably not in the price range and physical size you want.

That being said, AND I'm not sure how accurate the mw rating is - you might try this:

I've had my Optotronics 175mW go well over 200mW quite often. But it is quite expensive... best option, save up! You can't go wrong buying a quality laser from a reputable company. There are many ways to go wrong buying a cheap laser...

Sorry to go off-topic here. But I really wanted to ask someone who owns an Optotronics pen pointer.

Could you tell me how the divergence is, and if the beam at aperture is thin? I'm considering getting a 150 or 175mW model myself to take with me on the go.

Edit: http://lazerer.com/532nm-laser-modules This is what I found at Lazerer. I have no experience with them, and I'm not too sure whether or not it's a good company. They sell 30, 50 and 100mW 532nm modules.
