I didn't notice the 532nm AR coating. Must have missed it somehow. Okay. It is on the package of the last photo in the listing. It is kind of scribbled on there, so I didn't notice it the first time I looked. Good eyes, Alaskan.

Yea, he doesn't mention it you have to chase for it, I wasn't sure you saw that. I think they might be useful to build a diode pumped YAG to produce 532nm, but so tiny, don't know what knd of power could be obtained.

That sure is small. I wouldn't like to say with any certainty what power it could output. Due to its size, the input power can not be too excessive otherwise the crystal will suffer damage. I'm going to put a plain guess out there and say <2W of 1064nm. If anyone actually knows, I am interested to find out the answer.

Oh, and I desperately wanted to be able to rep you and put you over 10K Alaskan. Told you it wouldn't take long.

Here's an interesting flashlight that would look awesome with a laser diode and voltage monitor, I could do wonders with this nice tripod too but not sure I want this type of project at the moment!

That's cheap for one of those, they are pricey.

They are optical meters though, you need to set the wavelength you are testing in order to get an accurate reading.

Intermittent issue could be a dying battery? They are "not user serviceable" - IIRC you're supposed to send them back to coherent for a new battery.

That is cheap, Edmund Optics charges close to 600 dollars for the new model, I bought one of those for 100 bucks and was happy to get it at that price. Edmund Optics won't change the battery out for you, won't calibrate it either, but will fail or pass it's current calibration. You can "calibrate" the WL reading using a pricey pass filter which is fairly narrow, as narrow as is an acceptable error for you, but filters which are just a few nm wide are expensive. There are no pots or adjustments which can be made to calibrate it, you use the filter to know how far off the unit is, or is not, then make a numerical adjustment in your head, plus or minus the possible error of the line width of your filter.

If you change the battery, the unit needs to be recalibrated.



I don't understand why the guy I bought this from referenced the product as being a Edmund Optics unit when Coherent makes them, maybe they carry it, not sure: http://www.ebay.com/itm/Edmund-Optic...-/152521232647

Congratulations on being the first to go over 10,000 in reputation. I don't know what the power output might be. It would be useful to know what, specifically, it was designed and built for. I doubt the seller knows as he seemed clueless about the YAG in his listing.

You can "calibrate" the WL reading using a pricey pass filter which is fairly narrow, as narrow as is an acceptable error for you, but filters which are just a few nm wide are expensive. There are no pots or adjustments which can be made to calibrate it, you use the filter to know how far off the unit is, or is not, then make a numerical adjustment in your head, plus or minus the possible error of the line width of your filter.

If you change the battery, the unit needs to be recalibrated.

I don't understand why the guy I bought this from referenced the product as being a Edmund Optics unit when Coherent makes them, maybe they carry it, not sure: Edmund Optics Handheld Optical Meter No. 54018 - Measures Wavelength AND Power | eBay
Thanks for the info Alaskan!

Is your unit measuring WL & Power readings pretty accurately?

Id assume it wouldn't be cheap getting coherent to re-calibrate, let alone fix a possible "faulty issue"

The LaserCheck LPMs don't measure WL at all, they only measure power. They use an optical sensor so you must set the wavelength tested in order for the LPM to apply the correct adjustment to the reading using its built in calibration table. Optical sensor response varies depending on input wavelength.

Thanks Diachi,
Yer that would be to good to be true in such a little unit, I'm guessing the WL wouldn't have to be set exactly spot on though, otherwise you'd be carrying around a spectrometer when testing the power output of a laser with the lasercheck

No, a few nm either way isn't going to make a whole load of difference, it'll at least get you in the ballpark. But testing a 445nm with the LPM set to 532nm would surely cause quite the skew in your readings.

I haven't used my LaserCheck in a couple of years, never bothered with setting the WL with my measurements, probably should have. Then I saw this one on ebay earlier this week and bought it, the seller said it could measure WL so I thought either I didn't know how to use mine to do that, or this one had an added feature. I haven't received it yet, but that makes sense, I've never seen anything which could measure WL in such a compact package.
