15mW Labby Question






All you need to do is click on "ask the seller a question" on the auction
listing... I'm sure the seller would be the one to ask to be sure... :)

The Listing did say "DC Power Supply" and "with TTL and 5VDC interfaces"
Looking at the PS PCB... I'd guess a 5VDC Power requirement... 8-)

Yeah, see, I don't have an ebay account (not 18)

I guess I'll try to get my friend to do it or something.
 
looks like the old DX 35mW modules (i have one) mine outputs as much as 90mW or so

no idea what the output of that unit might be though

Well.... if you read the listing... it says "power level is variable generally from 0 to 40mW"
Not bad for a 15mW laser.... 8-)

Aixiz also has a "65mW" labby for US$65. I have three and they all put out over 100mW of green (after I put IR filters on them). They're not bad for the price either.. Very stable for not being TEC stabilized.
 
I see that the power is adjustable but how do you "tune" it? What is the frequency range? That's got to be new technology to tune a 532 nM DPSS.

Umm yeah.. It's a misuse of the word.. but I think you just like pointing it out...  ;) For real, though, they should change that..
 
Yes -- I like pointing out a company that can't use scientific terminology on a technical product correctly. Makes me question their understanding of the sciences in electronics and lasers. I see a lot of that on ebay too.

I can definitely understand that.. I also question Aixiz' knowledge of lasers and the science thereof, but the lasers I have bought from them have been good nonetheless, as has the price and customer service for the most part.. Many of the suppliers that forum members deal with regularly have no knowledge of lasers at all (DX, KD, VV, etc..) but still provide reasonably good products and service. As long as you're not going to the retailers with detailed questions about using lasers for specific applications, you should be OK..

I think one of the secrets of axiz and their labby style lasers is the factory seconds idea. I'm pretty sure they have made mention of it somewhere... I bought a 20centz laser scanner not long ago, and the 532 laser was the exact same as the one sold by axiz. The only difference being, the one in the scanner was rated 70mW and with slight tuning will easily hit 150mW. The ones sold by axiz are rated IIRC 50mW. This leads me to believe (as they state) the axiz lasers were sub par and rejected QC by companies like the one who make these scanners. And the same ones appear on DX as 50/100mW.

Its interesting how the Chineese manufacturing and distribution system works. So many companies simply trash the rejects, if not destroy them first. At least this way some cash is recovered other than recycling, and it gives the hobby such a great DIY resource.
 
We've done the same thing. Although we don't usually sell laser systems to hobbyists for no other reason than it's not our market we have provided portable lasers at very reduced prices when one of our military contracts changed what they needed. Lol, the cost of the change order covered any loses we may have incurred in getting rid of the overstock. They were not a bad deal considering they were brand new, never used systems. In any event, when we do end up with extras we often make it known to you guys.

From what I've seen the DX ones are slightly different..

I do believe that you're on to something there.. They easily could be rejects. Aixiz states that they came into a bunch of these units due to a customer of theirs changing their needs. The first one I bought I got to try them out. I was a bit skeptical at first, but I've had that laser powered up continuously since I bought it and aside from the usual power fluctuations of a non TEC-cooled laser it is still going with no reduction in average power. I've since bought two more and they both work great as well. They may be factory rejects, but they do work well for the price. Plus if you buy a few you end up with some spare parts whenever one dies..
 
I think the issue of Aixiz using incorrect terminology in their ebay listings is more a symptom of the dumbing down of linguistic excellence that humanity has been seeing since 1994 (around the time shell accounts with access to the internet started spreading from the Universities to the general public).  I would not be surprised if we were to find that the incidence of such abuse of scientific terminology was much lower in printed matter such as catalogs.  I do not know what it is about networked computers that brings out the laziest type of writing habits imaginable.

Just like a few people already stated, there is no excuse for a company selling technical equipment to allow such a misleading error to persist in their listing.

The first labby I bought was the Aixiz 15mw 5v.  It does *not* run off of 120v, however I often use a Radio Shack 4.5v 300ma wall adapter and get over 50mw from this laser.  With 3 AA batteries I get around 35-45mw, but the beam looks about the same.  This laser may be similar in some ways to the DX 35 labby, but it is not the same one as seen in the picture.  It's confusing because the one in the picture shows a module which breaks apart (after removal of the screws) in the rear quarter of the heat sink. ...similar to the DX35 from what I've seen in Wannaburn's thread.  However, the module I got from Aixiz in November of 2008 had a style in which the heatsink came apart in the middle.  Clearly different from the DX pictures I've seen.  However, I have not taken this Aixiz module apart to see if it breaks down like the DX does.  That is a project for sometime in the near future.
