What's really the best LPM?

[xStatiCa]

there will be a new LPM in our stable in the near future

I didn't know that. Looking forward to hearing more about it. Will I be able to measure my 0.00001mw laser with it though (just joking around in case you miss the wink smiley).

It would be great for the Desktop applications to be based on java for cross platform benefits.

I also like the Scientech equipment that I have.
It has a built-in calibration device for accuracy.
I have also used MISTERWILLING's LaserBee unit for some Red lens testing
with good results.
One thing I have found out with all of these thermal input meters,
is that you need a draft-free room for accurate measurements.
When I was doing some Red diode testing one late cold night,
the heater vents were affecting the power readings I was obtaining.

If ambient temperature and/or draft is a problem for your Scientech, I have a couple of different enclosures available

The thermopile fits inside the enclosure. The one with the extension is basically just a draft shield. The one without the extension is also solid filled with closed cell foam for insulation.

Peace,

I was talking about the Kenometer Pro...
If there was something in the works for a new LaserBee product..
we wouldn't unveil it until is was ready for the Market...

For what you want to test... have a look at this one... it seems the
price has dropped since we bought one....

Thanks for the link. I actually found a Sper cheaper than that (around $200) somewhere which seemed to have the same specs but I can only get one for now and the need for higher mw ranges (500mw+) means I am was better off with a Laserbee I or Kenometer PRO. I decided to get the Kenometer PRO. I will just have to wait until I have more funds to get a smaller range meter for the 0.5mw range and decide then if it will be worth the cost to get better accuracy at 0.5mw. It would be great to have a handheld unit though... I could then take it to the stores and test the cheap 1mw lasers if the lasers are sold without packaging . One day. I am over that for now though. Bring on the Kenometer PRO! .

Check out this small little LPM here.

The LaserCheck is good if you need a quick check in the field because
it is small and fits into a pocket..

One of the problems with it is that is does not test 405nm very well
and if you are testing a 532nm Green Laser without IR Filters the reading
will be way off because it is an Optical Sensor and you have to adjust it
to read one wavelength at a time...

It also has a very small non backlit LCD screen that is almost impossible
to read while you are taking a reading (we have 2 in the Shop)

Brand new it costs $365.00USD plus shipping...

Thanks for the info lasersbee. There is always a vet to save the day.

Lasersbee has a Coherent LaserCheck. It appears he got it from someone else on this forum who claimed it was pretty far off on readings(30%). On another forum someone else mentioned maybe that is why they specifically used the word *check* in the name to imply it is not as accurate .

 

[lasersbee]

J.BAUER Electronics has 2 LaserChecks...
One brand New From Coherent and one from a member on
another Forum... The one here had some issues and we passed on it..

The one from Coherent cost us over $500.00 by the time we paid shipping...
Brokerage Fees.. Duty and Taxes.

That is speculation (*check*)... The LaserCheck is stated as +/- 5% accurate...

actually you can get the sper directly from aixiz...

Hey BobH would you be willing to sell any of those?

I see what you did there.

I see what you did there.

LOL! Nice trick! I'd like to see you measuring <10W with that though

a simpleton troll and I got distracted by the vehement personal attacks by a few other Reaganesque respondents, equally ignorant of socio-pharmacology.

Don't try to blame your Drug Condoning TROLLING on others....:tsk:

The razor blade indicates Joules, not Watts.

I'd have gone into other methods of measuring laser power without a meter in the "laser output" thread that was started here yesterday, but that thread was derailed into being about the OP by a simpleton troll and I got distracted by the vehement personal attacks by a few other Reaganesque respondents, equally ignorant of socio-pharmacology.:horse::thinking::tsk:

I would love to know other ways to measrure power.

Me too! ^ btw... 69th.
