Diode Pointer Quick Start Guide

Repeat the near and far field adjustments steps mentioned previously.
The goal of the adjustment procedure is to get the CO
2
beam and the Diode Pointer coincident within 100
microradians, which is equivalent to 1 mm at 10 meters of misalignment as the recommended outside tol-
erance of alignment. Anything more precise and accurate is desirable, but not necessary. Final accuracy and
precision alignment is completely dependent on the final use of the pointer. Most articulated arm applica-
tions require 100 micro-radians, while a simple lens system requires only 1 milliradian. The outside tolerance
or acceptable misalignment is 1 milliradian, or 1 mm at 1 meter.
Congratulations!
The Diode Pointer is now correctly installed and the rest of the beam delivery system can now be installed.
