Why do you want to pick apart and LPM a insignificant toy quality laser worth very little to begin with and an almost nothing resale value?
What difference does it/can it make? What is the purpose that makes measuring it necessary?
They are what they are regardless. Just use them safely and enjoy what you have.
Seems to be "much ado about nothing" really.
Well, They sure are not “toy quality” In fact, I am quite impressed with their cost/quality ratio.
As I have said in previous posts, I want to measure output, because I am curious to find out real vs claimed. Also, other member have indicated interest in knowing too.
Get a good pair of laser safety goggles and don't expose anyone else to eye hazard either---damage to eyesight by lasers is usually permanent.
See:
https://www.survivallaser.com/Safety_Goggles/cat556089_826120.aspx The same people make complete kits with all the parts to assemble a laser yourself very easily that are way better/higher quality than what you bought if you want to give easy no skills building a try, as well.

As I have said before, I have several pairs of safety glasses, including a couple from EP, I have also told you in at least two occasions that, unless I have no other choice, I am reluctant to import from outside the EU. Import charges and all that jazz!
My friends are about my age, we are all in our 50’s, well educated and, conscious of what we play with. Don’t worry, we are safe, even when we get hammered.
Keep in mind to double visual brightness requires 4X the output power for any given wavelength, so a 4W 445nm is double the brightness of a 1W 445nm.
A 1W green should be approx 10X visually brighter than a 1W 445nm blue based on standardized eye sensitivity of defined ideal human visual system eyesight.
I am aware of this, but thank you for reminding me.
You would be much better off buying a better quality laser than a Tracer LPM for $350 to measure a the output of a $50 laser.
I am only thinking of buying an LPM. But, if I do, I am sure it will be used with future purchases and DIY builds, so worry not, I will get my money’s worth.
Also FYI, it’s 60$ But of course, you have to add... Batteries, safety glasses (cheap and worthless than they are) charger, star attachment, and the cheap case. Oh, shipping too, and once it gets to the U.K. handling and custom charges. All in, I paid the right price and got it faster from a EU seller that, if not happy, will accept returns 30 days after purchase. Not too shabby I think.
Maybe to to a University that has an LPM and ask them to measure it for you or let you measure it
WTF?.... Yes, Encap, universities are always happy to let any old soul that walks in use their equipment. I’ll sure give it a try!
Cheers!
Ps: Sorry for the double post, I was busy with other things and that took some time to compose.
