Subject: Systematic error of the power meter (RM9, Ophir) 

In the spec sheet, the systematic error of RM9 (power meter, Ophir) is 5%.

This is not very good.

However, the power meter was calibrated in the company at 808 nm wavelength and the deviation was 0.6%

This is very good.

If the 0.6% error could be applied to our power measurement, the systematic error would be improved.

Thus we inquired the error of RM9 to Ophir.

The answer was that the error is not 0.6% but is 5% at 1064 nm.
