Absorption vs. Wavelength of Various Pyroelectric Sensor Absorbers
9.1.2.2. Method of Calibration
The absorption of the various Ophir thermal absorbers
can vary from disc to disc. Therefore, all Ophir absorbers
are individually calibrated against NIST traceable
standards.
9.1.2.3. Total Accuracy of Calibration
A detailed discussion of Ophir calibration accuracy is
available on the Ophir website at

9.1.3. Recalibration from a Known Source of Laser
Power / Energy
1. From the main measurement screen select "Menu"
and select "Calibrate". Select "Adj:" and select
"Specific: this laser only".
2. Enter "Laser" and select the proper laser wavelength.
Enter "Average" and enter the desired averaging
period.
3. Apply the known laser power/energy.
