New 250mW-500mW Green lasers at DX!

I don't know about you guys, but the carry bag seals the deal for me.

;D


Anyway... The instructions say "Viasho" right in the last sentence.. Could it really be? The diode life is a little short. Maybe they are made from cheaper parts by special request....


But the labels look cheap to me. :-?

Optotronics requests special 2.5W N-Light diodes for their RPL series. These probably use the standard 2W IR diode to save money.

Yeah, i know about the n-Light diode.. But even with a regular 2W this seems "cheap".. And shouldn't the diode life be closer to 8000h?
Maybe it's a slightly overdriven 1.5W diode, just to get the price down.


On the other hand, the 500mW is rated as >500mW.. And i doubt a quality manufacturer would want to start making cheap stuff.... Hmm.
And i just wanted to order a >400mW TEC cooled CNI.. Now what?


EDIT: $1250 is less than the CNI would cost me with shipping and custom fees..

The chances of them selling to someone who even has a meter to figure out the mW of their cheap laser are pretty slim, so they're probably saving some good money. What they should really do is sell power meters for cheap.

AMEN!!!!

Would cut down the whining significantly

Peace,

i wish i had enough money to test one for you guys

;D I'm almost tempted to "test it for LPF" myself..


No, i'm in a serious dilemma now.. If this really is Viasho..... And i've had no bad experiences with DX so far, when it comes to returning a laser until a good one was found.. DAMN! What to do?!?

>500mW Viasho or >400mW CNI? And CNI does NOT guarantee it'll stay above 400 for more than 3 minutes, even with a TEC.

Well, this one won't either.. It'll go to zero at 2 minutes, if i understood the description correctly. But this is one part, that is making me wonder...

what 400mw cni are you tlaking about do you have a link?

No, i don't have a link.. I don't know where similar models are being re-sold.... Not even what they are called (i forgot)..

I wanted to buy directly from CNI, like last time. I just need to go to the bank and send the money..

wow at work i didn't look close but they are rpl aka viasho read instruction sheet on dx site at bottom it says vioasho is not resposable for incorrect use they just have the non adjustable tailcap

Well maybe the instruction sheet is viasho, but is the laser too ? ;D

hmm i wouldn't know mine didn't come with a manufactuer papers
my rpl

crap i hate that i try to add to my thread and it gets deleted :-/
anyways i'm sticking with Jacks RPL'S

Hi John,
Thanks for the heads up on this.
Actually Viasho doesn't include paperwork as far as I'm aware of, the only paperwork I get is one sheet for the entire shipment, listing each laser and the 12 month warranty.

Viasho doesn't make a 500mW unit, if they did, I would have then in my hands as ours use the better/higher quality 2.5W n-light diode, as well as a few other unmentioned higher spec components (not listed as then TL and others would say "our has this too", so I learned my lesson and am keeping my mouth shut on other design specs.

I just posted this following text in reply to Igor's post on the DX website, it probably won't be there long, so I'm posting it here as well.

------------------
Everyone has the assumption that just because a device may come from a common manufacturer, that what looks the same is the same. Actually manufacturers are very accommodating and will build to suit.
If the retailer says for instance that I want the unit cost to be $$$ and I don't care what it takes to get there, the manufacturer can and will decrease the quality or power rating of components to get there. Notice the big 30 day warranty, after that you're out of luck. Not much as far as standing behind the product.

I could do this as well, but as of yet I don't, but it may be an option in the future.
As it stands now, we use a more powerful diode (don't care what they may list in their specs), better crystals and other components. This allows for a standard 1 year warranty (we stand behind our products).
One more thing, look at the variety of products that DX sells (nearly everything under the sun as far as high tech goes). You would have to be pretty naive to think that they are actually testing any of these at all. They ship every unit that they get in and ship them out to customers without even opening the package and if there's a problem, they are pretty much out of the picture. As their warranty says, if the unit fails within 30 days, you will pay the shipping both to and from Hong Kong for a repair, even if it arrives DOA. That along is going to cost upwards of $70 USD and many weeks without your laser, and who's to say the repaired, replaced one will be any better.
Lots of luck to those to think they're getting a bargain.
----------------------------------------------------------------------------------
ps, I think I may start offering a "barebones" RPL in the near future (as a seperate product from the RPL)
With the option of only a 30 day warranty, with no support other than providing the address in China to send them back to if they are not to the customers liking. These "barebones" products will also be manufactured with the basic low cost diode and design configuration that these overseas retailers are using. Hey, if pirce is all that's important, I too can compete, but it has to be a level playing field offing the same thing and the same amount of support and warranty, right?
The "barebones" units will not be 400mW units at all, It probably pretty rare to get one in their low cost configuration that can actually sustain 260-300mW for more than 1 minute or so.

Give me some feedback, is this what anyone's looking for?

Thanks
jack

So what you're essentially talking about is selling these same, lower quality grade lasers for cheap prices, but actually providing proper testing on these units?

I reckon that would be a good deal. One of the key problems is that the cheap units are so variable. If you actually know exactly what you're getting, that makes things much better.

If DX is ever going to be a serious laser reseller they NEED to invest in a power meter and IR filter so they can test these expensive lasers.

Hi Razako,
They don't need to test them, and they won't. They don't have time for that and if the price is low enoguh people who don't know better will still buy them. In fact they may actually be drop shipping them and not touching them at all.
Since the buyer is going to be responsible for any shipping costs both to and from China during the 30-day warranty, it costs them nothing if a laser arrives at the customer DOA, is under-powered or fails in the 30 day warranty. On the other hand, testing, burn-in and real customer support takes time and time is money; so they actually lose money of they test them as they would find failures they couldn't sell and would need to be returned to the manufacturer at their cost instead of the customers.
So the customers are their "laser testers" who alos get to incur the costs of shipping.
They could care less about their reputation, they sell hundreds if not thousands of other products and they are telling you up front that these costs are your's to pay, so they are honoring what they said they would "nothing other than passing your failed laser on to the manufacture for them to deal with and all incurred costs will be yours".
They sell stuff, not test, support or warranty, that is between you and the manufacturer.

enough said on this topic, I've got customers to support and it's been a really long day.

naw for me Jack the ones you have been providing are nice units i want quality optotronic units and was wanting to upgrade but hey i get another bonus next year and thats when i'll get me a 350 or a 400 rpl

I think Optotronics uses the same labels. I do agree that the labels look pretty cheap. (They are very general and do not indicate the output or wavelength. If you are really concerned, I guess you could buy a custom label or something.)
