Checking Laser Reading Power Levels:

Note: you CANNOT see 830nm, you CAN see 690nm (appears red)

- all lasers of same wavelength should be in the same range (e.g., all 690 lasers should be between 13.01 and 13.9) - adjust lasers with small screwdriver.

- when using power meter to measure from the laser o 690nm should read at 13mW or 12.5mW(unit?) o 830nm should read at 10mW

- when using power meter to measure from the probe end of your fibers, expect your fibers to lose between 30 and 50% of the light o 690nm should be about 8.45 o 830nm should be about 6.45
