Module Specification Description

# 520nm Laser Module Specification

1. Machining accuracy of the 90° conical mirror: current machining tolerance is (±0.006°). Tolerance leads to accuracy deviation, and zero‑tolerance manufacturing is practically unachievable at present.

2. After passing through the conical mirror, the light beam travels through the glass tube. The inherent optical properties of the glass tube will cause beam radian and deflection.

These two deviations may add positively, add negatively, or counteract each other. Therefore, perfect uniform beam accuracy cannot be achieved and can only be controlled within a certain range.
