The main functions of the focusing lens:
1. Improve the ability of the edge beam to enter the detector;
2. In the same main optical system, the additional field lens will reduce the area of the detector; if the same area of the detector is used, the field of view can be enlarged and the incident flux can be increased;
3. The non-uniform illumination on the photosensitive surface of the detector can be homogenized.
It is mainly used in laser marking machines and stage lighting, but also in scientific experiments and laser measuring instruments.
