How to Collimate (Reference)

1. Point the telescope toward the light. Turn the diopter ring and
adjust the diopter so that the cross hairs are clearly observed.
(Turn the diopter toward you first and then backward to focus).

2. Aim the target at the peak of the triangle mark of the sighting
collimator. Allow a certain space between the sighting collimator
and yourself for collimating.

3. Focus the target with the focusing knob.If parallax is created
between the cross hairs and the target when viewing vertically or
horizontally while looking into the telescope, focusing is
incorrect or diopter adjustment is poor. This adversely affects

② Sight object A in left position and read the Vertical angle value
VI. Rotate the telescope. Sight object B in right position and read
the Verticail angle value VR.

③ Calculating， i=(VI+VR-360°)/2

④If i ≤10"，no adjustment is necessary. If i ＞10"， adjust it.

Adjustment
(Please adjust through the software if the differences between

the index is too big.)

9.7 Check & Adjustment of the laser confocal and
coaxial

(This step was done after finishing the inspection and

adjustment of Item 9.4 and 9.5)

Laser confocal

Send the laser after aiming at the target,and then check the

facula’s diameter.It should be minimum.If it is not,loose the

screw on the laser pedestal,and move the pedestal until the facula
be smallest.

Laser coaxial

The crossline should be in superposition with the facula after
aiming at the target.Make the facula in the center of the crossline
through the four screws on the pedestal.(as the picture below)
