Default Sanwa Laser Power Meter LP1 & calculate 532nm green Laserpointer

Hello together

i think i need your help guys ;-)

i have one question, i have this product, Sanwa Laserpointer LP1
and i need your help pls.

The LP1 is callibrate of 633nm, but i want to check a laserpointer 1MW with 532nm, is there any formula to recalculate for an virtue of 532nm. I cant find this 532nm in the manual, maybe you can help, that would be nice ...
Iam not sure whats the bill ...




thank you so much

wishes

Hi Jim,

thanks for your fast reply, how do you calculate that ?
is there a special formula ?

488 nm x 2,08
500 nm x 1,93
515 nm x 1,71
550 nm x 1,39
600 nm x 1,12

532 nm ? or 1,34 ;-) but how you calculate that

normaly it must be between 1,39 and 1,71

thanks so much

wishes

You are right... the number seems off.

Looking at the data on the Graph
Between 515nm and 550nm the graph is fairly linear.

The spacing between wavelengths 515nm and 550nm is 35 points.
The spacing between multiplication factors 1.39 and 1.71 is 0.32 points
That is a ratio of about 0.0091428 per nm at that part of the graph.

If you take the different from 515nm and 532nm (17 points)
and multiply it by 0.0091428 you get ~0.1554.

Take multiplication factor 1.39 and add 0.1544 and you get
roughly 1.545 as the multiplication factor at 532nm.

Since that is an Optical LPM it will not read correctly and
probably high since it will also see ant IR that is not completely
filtered out.

BTW... you are in the WRONG section of the Forum this has
to do with testing and LPM calibration. It has nothing to do
with Companies.
Ask one of the Mods to move it for you...

Hello Jerry,

thank you so much for explaing, ok so i will add now the factor x
with 1,545 - but i think thats correct 1,4554

because 1.3 + 0.1554 = 1,4554

Thanks, will ask the mod to move the thread

Thanks again Jerry

wishes

I found 1.545 before check Jerry's answer! I'm good on maths like you Jerry
