The TRUE output of my laser (I got a powermeeter) !!!

[liteglow]

Well..
There have been a long discussion about my 1Watt green dpss from Viasho laser !!
And now I have got myself a (corenheit?) laser meeter.

It can measure Red\Green\blue\IR laser from 0mW up to 1Watt !!

Here goes the results:

*Maxyz modules RED lasers

Payed for >200mW Measured to: 201mW
Payed for >200mW Measured to: 199mW

After the beamqube it was 388mW (more less)


*The green Laser from lasever

Payed for 100mW (from spec) and measure the laser to be 120-130mW


*The blue laser from Lasever
Did buy the laser from spec as a 100mW unit, and measured to 136mW !
Then it was sent back to LasEver China and payed 500$ more to upgrade it to 180-200mW !
It was then measured to be only 116mW of blue !!


Then my green 1000mW from Viasho laser China!
payed for: 1000mW measured to: 440mW



Conclusion :
Laser from USA 0.0% loss of power from payment
Chinese Lasers 60% less power than payed for !!


Can we trust that we get what we pay for ??
I do understnad now that some ppl here on the forum maybe was correct when They told me that it seems like a half watt of laser..... :roll:
I will write to Viasho and ask if this can be correct !!



But remember that the handheld powermeeter usually can have 5% wrond readings...

Send both of them back, and demand they pay shipping both ways.

EDIT: You do have the lasercheck set to 532nm or 473nm?

[cruch]

OOOOHHHH....!!!!

This got me worried!!ALOT
Maby I go for the CNI lasers instead of Viasho ?

Cant belive 440mw of 1Watt. :evil:

[liteglow]

Yes I did adjust the settings on all 3 diffrent wavelengths !!
Red, green and blue !!

About the blue I can try to contact LasEver, but if they use as long time as last time I did sent it to them.
It`s not worth the time of waiting...
And about Viasho, I will dont judge anyone untill I got reply from Viasho\nono !

[cruch]

make me think alot!
I want a power meter! Someone who has the Handheld Laser Power Meter Model 3803? Please PM me.

This IS a must now....so this is pri. 1!

[buffo]

Wow!

Well, this is exactly why everyone is always saying that a power meter is an important part of any hobbyist's equipment.

You know, Dreambeamz was right all along... He was the one that first called the power output of that 1 watt green laser into question. But he also had a brand new 1 watt CNI laser to compare it to, and a power meter to check it's output. Eh - kudo's to George for a good call. 8)

I agree with Dave on this one though. Make the manufacturer pay for shipping BOTH WAYS to get the bad lasers back to them and the replacement lasers to you. If they refuse, post like hell about it!

Still, it totally sucks that you got screwed like that Philip. Sure hope the manufacturer will make it right...

PS: At least the Maxyz modules are OK! (And less than 5% loss through the polarizing beam-splitting cube... Not bad!)

PSS: Cruch - the Coherent Lasercheck wands can be purchased brand new for about $300 from Edmund Scientific. (You can even order them straight from the website...) Those units are good for up to 1 watt of power.

Damn, that sux... I'm sorry for your "loss". Post like hell anyways. If enough of us point fingers maybe the sellers'll start verifiing their products and sending out good products. Maybe marconi should make a guide on how to properly test your laser before you ship it to a buyer. :roll:

This also sux because this is one more thing I need to buy... :P

[BoomDog]

Wow, I was about 12 hours away from purchasing one from them, nono-shen had even gotten an invoice together, until I realized it was technically illegal to import lasers w/o a variance, and I didn't want to mess with that while starting out. I must say I am very glad I purchased from Aixiz now. Sorry to hear about that though, major bummer. Hope you can get either your money back or a new laser...

[Banthai]

I have mentioned before in another thread .... but my CNI and lasever lasers arrived over spec

green 450mW doing 560mW
red 400mw doing 640mW
Blue 150mW doing 152mW

so CNI certainly are the "dogs danglys" and the build quality is better than anything else ive seen


all the best ..... Karl

[liteglow]

yes I dont like the loss of power !
But I do trust Nono, and I waiting for a reply...
I`m sure this can be worked out some how
