Technical Guide
Calibration Procedure, Apogee Elite Lasers
Record all calibration data on the Calibration Accuracy Report , see “Appendix B” on page 69
for a sample of the form.
NOTE: For the following procedure, the laser’s coolant temperature must be at 65 C°.
WARNING: Keep the Cal Port Window clean to ensure proper calibration. Failure to keep
the Cal Port Window clean may result in incorrect Energy Meter calibration.
For the Apogee Elite laser, use the 7-mm handpiece.
1. Connect the optical receiver cable into RX2 of the Laser Control PCB.
CAUTION: The fiber optic # 97 must be properly routed and secured.
2. Install the handpiece into the Cal Port. Enter ‘Constant Voltage’ program. Select a
wavelength of 1064 nm (Nd:YAG). Place system in 5 ms, 1 Hz mode. Adjust the voltage
to achieve 35 watts through the handpiece into the power meter. Verify meter set to
‘NIR’ or ‘YAG.’
3. While firing laser, adjust VR1 so that the energy reading of the Cal Port displayed on the
computer screen agrees with actual measured power. Make note of TP3 final voltage at
which Cal Port was set.
4. Make note of the PFN voltage at which the Cal Port was set.
5. Select a wavelength of 755 nm (Alexandrite). Without making any high voltage
adjustment, fire laser into the Cal Port, and make note of Cal Port voltage as displayed on
the computer monitor screen.
6. Fire into the Ophir and make note of the power meter reading. Verify meter set to ‘VIS’
or ‘ALEX.’
7. Calculate the Alexandrite slope in joules / volt for the Cal Port by dividing the Ophir
Power Meter reading by the Cal Port voltage from step 5. Make note of the ratio.
8. Exit the Constant Voltage program and prompt the Testall program.
9. Using a keystroke of “U”, enter the ratio as calculated in step 7.
10. Press “x” from Testall program to prompt the Constant Voltage program.
11. Set laser for 755 nm, (Alexandrite) 5.0 msec, 1Hz, PFN Voltage to level noted in step 4.
12. Fire laser into power meter and make note of power reading. Fire laser into the Cal Port
and verify that the Cal Port voltage as displayed on the computer screen agrees with the
actual energy measurement. Make note of the Cal Port voltage and power reading.
