How different are all the pen lasers from eachother?

It seems that the optotronics pen style lasers get rave reviews, but they look identical to pretty much every other pen style laser I see on sites like wicked lasers and such. I know the body (host) has little to do with the longevity of a lasers life, and the internal parts are the most important. So my question is, Does optotronics use their own internal parts that will last a long time compared to other lasers? or are they the same internal parts, just tweaked a bit?

OFc they are diferent parts. but listen these 3 hints:

1.-Don't mention wicked lasers anymore. They are a rip-off, forget them.
2.-Judge the lasers by their reviews. Look here in LPF for good reviews on almost all lasers.
3.-Before going optotrnoics you might oniser O-like.com, who have a really good reputation here and sell realy nice units.

It's not only about the quality of the laser parts.

It's also about the quality and effort the seller makes to test that its product is not defective or under spec.

I'm sure some companies just get their laser pointers from a Chinese manufacturer and then sell them without even a slight test, while others do and even offer you to measure and make a certificate themselves.

I have 3 wicked lasers, and all 3 are under spec and unstable, I was too late when I discovered LPF...

Hi BassClefJeff84,
Read my in the following thread, it's the 4th post from top.

I've heard that so many times xD

just stay away from wicked and go O-like or Optotronics.

or.... laserglow and novalaser.. but thet ghave higer prices... .. i don't know HOW optotronics choud have a 1150mw laser at 200 $ and other seller ( included dragonlaser that i neever inderstood if is good or not)... they sell the 150mw at about 400$------ the double! why?different diode quality? opto is cheaper and have a 1watt diode XD others.... only 0.5 watt diode. byt the efficience of the diode i think is alot better... so i don'0t know if is better to have an efficient 500mw diode or a 1 wat diode less efficient. baybe...is the SAME....

I bought from Optotronics (located here in the USA) so there are no customs to take your laser. Also I trust Jacks judgement on the lasers he sells. He has a very good reputation. I have also bought from Wicked Lasers and their lasers are of good quality. I have several of them and they are still going strong.

One other place to buy from that no one thinks about, Howie Glatter www.skypointer.net His page advertises the 5mW greens but he has much stronger ones also, you just have to ask for them. I have a few around 50mW and they have the tightest beam and the lowest beam divergence I have ever seen in a laser. At 40 feet the spot is smaller than a dime. This also means you can see the spot much further away than many others. His laser are very dependable. He takes them apart and raises the current to the laser diode to 290ma and some of those lasers are above 50mW. When he gets the lasers the current is turned way down so the laser will pass FDA standards. He then colimates the lens if needed and warranties them for one year. They may not burn much but the divergence is the best you can get in a laser. Email him to see what he can do for you.

So, what differences should I expect between a >100mw green pen from o-like, and one from optotronics?

I've been wondering about that as well. Are the beam diameters of the o-like modules similar to those from optotronics? What about the divergence and burning ability compared with a CNI?

Well as I mentioned earlier in my threads the Optptronics green laser lights matches instantly and has a divergence of 1.2mrad. I have a CNI laser and divergence is horrible. The Opto is much nicer and read this from Optptronics:

Output power is verified with a Coherent FieldMaster GS
power meter and test results are recorded on the instruction sheet.
These lasers typically have 1-4mW of IR; however this is not counted
towards the +150mW total of 532nm.
Average output >150mW
Typical peak output up to 170mW


Mine is pushing out 156mW with standard Alkalines. It burns leather and plastics very well.

emc2.... could you test the laser using 2 nimh battery that are usually from 1.38volt and 1.22? i have a kaleidoscopic 30mw from DX.. and it works VERY WELL also at 1.28 v... so the driver is perfect for rechargeables. i tryed to use a lion 10440 and a spacer... the results is quite the same... the burning ability... almost the same. ok.. with alkaline you have TRUE 150mw.. but.. using nimh?...how could be?...120...130.. 140 ? maybe boot leg can say it ...... ( is a strange think to test and sell laser with fresh alcalines!!! everyone know that the most important power source udes in laser are RECHARGEABLES......)

Well I don't have any AAA rechargeables and I don't have a laser power meter. All i can tell you is two AAA rechargables at 1.2v each it would be like inserting two batteries that are somewhat drained to that level and the laser output would be lower. 3.2v gives you max output. I personally would not use rechargeables because of the low voltage. Sure they save money but I don't care for them.

They may provide a lower voltage, but rechargables actually sustain their voltage for a lot longer than alkalines. Unless you switch out batteries when they're 25% drained, rechargables are the way to go. Lithiums are best, but considerably more expensive.

Hmmm, that is cool. i will keep that in mind. i know the Eneloop rechargables are the best on the market right now. But I wish they were 1.5v instead of 1.2v. http://www.eneloop.info/

I am currently using the Energizer advanced Lithiums.
