question
1.in your email you said you have compared the green laser pointer of us with the red 200mw one. but it is brighter
2.you said the red one is broken have you tested the output by a power meter? if yes can you send a picture to me
3.it is a 5mw laser pointer how bright you are willing for
it is two 3.7vdc li on batteries . but comparing the brightness there is no problem for the output. for the output only a laser power meter can tell the real output. not a comparation between two lasers.
frankly speaking if a pointer is <1mw the price is about double. it is eu standard and if...
can you open the link in my reply?
yes and I do not think to compare two laser pointer with different wavelength is a good way to compare a good laser pointer
frankly speaking. the laser diode we have used is osram 10mw . the real output of the diode can reach 20mw sometimes. so that the output...
I cannot add an attachment , I had put it in my baidu link
here is the picture the customer sent
this is the email he sent to me. here he did not tell me which wavelength it it. but from the picture I guess it is a 635-638nm one. http://pan.baidu.com/s/1mhVJjza
here are two pictures he sent to...
here is the complain I received from a customer:
This is a comparison between what used to be a 200mw red laser. 5mw of green is much brighter than this.
and he gave me two pictures as comparison.
from the picture. the so called red laser module is nearly the same brightness as our green...

absolutely correct. if test the output it must be 12mw around.
by experience, it is about 10mw.
and ours is very clean line effect, the other one is very dirty

a customer bought a 10mw green line laser module from us, but he said it is too weak for him, and he does not trust the output of it although we tested all laser output before shipping. so that I have to put the case here, if there is someone can answer the question here, and if someone can help...

, the 638nm is 2.8mw...
here is a judgement for me and a buyer from us.
we have some <5mw 638nm laser pointers for sell. but today, a buyer says, "selling cheapest stupid chiniese products with fraud features NICHT KAUFEN HIER". so that he is not satisfied with it and left me a ng feedback.
I have opened this new...
