Described step 2) comprise the following steps:
Being fixed on by the first lens debug through feeling relieved debugs on support;
Adjusting the first parallel light tube, make it vertical with the end face of the first lens barrel, making the second parallel light tube and the first parallel light tube angle for meeting the demands;
Assembling is through the second lens debug of feeling relieved, the angle of the second lens barrel is adjusted by plus-minus pad, make the end face of the second lens barrel vertical with the second parallel light tube, now the angle of the first lens and the second lens axis is exactly the angle of the first lens barrel and the second lens barrel, is namely the angle between the first parallel light tube and the second parallel light tube.
Described step 3) comprises the following steps:
Two lens through angular setting are put on altimeter, translation first lens, find the peak of the first lens and measure its height;
