Hyperion Laser Power Meter For Sale: 2W, 6W, & 20W Version






Yes-- I suggested he check that out-- he is away from his Hyperion for a few days but now knows where to start--that was a great insight to add that btw.

I've finally found some free time to check out
your LPM...
Looks well built. As I had previously mentioned in
a Post... I did spend quite a bit of time carefully
removing the LCD from the PCB so I could install
some 0.1" inline M/F headers.

We just did a standard power test that was not
what we expected. At 500mW your LPM seems
to read +11% over at 557mW checked on our
Coherent LPM.

How do we re-calibrate the meter ???
What is the exact procedure ??
The manual does not give enough information as
to how it is done correctly and I thought I'd ask
before we tried.

BTW why can't we print out the 2 Manuals ??

Haven't tried to do much with mine yet. I did check the uncoated sensor I got along with the coated one and it seemed to be pretty close to what my other LPMs measure. I have a micro USB to USB 2 cable coming that should allow me to use the other sensor. The only thing that I would change is to have the meter in a case. I just keep it wrapped up in the ESD bag it came in.

I put rubber feet under mine like I do with
our LaserBee II OEM PCBs. That keeps the
PCB away from anything on the work bench
that I may have missed when cleaning.

My sensor is coated with something that is
light gray in color.... It's difficult to get a full
450nm mutiwatt multimode beam onto that
small 6mm X 6mm active area.

Yeah... Astralist had offered to supply cases
for free to all his LPM customers.. Still waiting
for a case..

I don't know why Astralist doesn't check his
Sales Thread here more often... :thinking: I could
really use the info to properly re-calibrate his
LPM.

When I open a Sales thread I make sure any
customers are taken care of ASAP or at least
within 24 hours. I know he is in a different
time Zone but still...

I think I heard he was out of his home location and was not able to get internet access. Don't remember when he's supposed to return.
 
Whoops.. sorry for late response.

Jerry,
So you wish to calibrate the LPM?

I thought i already give a simplest manual.
Yet it seemed the manual still giving an unclear procedure..
I will rewrite the calibration process on the manual.

The thing is that you cant re-calibrate the Cuprum by user side.
The Cuprum intended for limited user so that it's locked, sorry.

Here is the recalibration process (without computer):
  1. enter the calibration menu
  2. press DOWN (about 10 secs)
  3. shine a stable laser with known power onto the sensor's surface.
  4. when the display/reading doesn't increased anymore (it will still change up and down within the last two digits because of noise), press UP to lock the calibration.


[EDIT]
About the calibration, i'm sure your coherent sensor is calibrated using 1064nm laser
My reference is calibrated using alexandrite laser
and it's calibrated by the sole Ophir distributor in south east Asia region (including Indonesia), here is the website: http://innov-global.com/
It is indeed giving a higher value compared to my other reference sensor which is calibrated using 1064nm laser.


Hope this help

Pradipta

Thanks for getting back to me.

Your answer is confusing...
1) you say the LPM can not be calibrated...

2) you explain how to calibrate it.

The calibration procedure you give is still
not clear. At what power do I calibrate the
LPM...

Or

How do I set the known power of a Laser
in the calibration procedure. You only mention
an UP button to lock the calibration.

Our NIST traceable Coherent LPM is set to
compensate and correct for the 808nm wavelength
we use for our in-house calibrations. So the 755nm
you use and our 808nm are quite close in wavelengths.
So I don't believe that is the difference in our power
readings.

[EDIT]

It's OK... I found somr data on which buttons to use
to re-calibrate the LPM. I'll let you know how it went
when I find some more time to play with the LPM from
you.

Can't tell you that, but I paid $25.00 for shipping and it arrived in less than two weeks. It might be worth it to you too as it comes with tracking and you can setup delivery to meet your needs.
 
Try the USPS tracking service. That's where I got my information. Of course, I assume your live in the US. If not, it may take longer. It could be showing up any day if you are in the US.
