Classification of red laser modules

The function characteristics of the red laser module are as follows:
 
1. Cross-line module: the principle is adjacent to the straight-line module, projecting two straight lines perpendicular to each other;
 
2. Light spot module: according to the user's plea to project a different pattern, including advertising text, spot spot module in the cost category of products for laser pointers, laser toys, etc., military for laser sightings and many more cluttered military products, east-west work for laser horizontal ruler, laser measurement of things and other products and drilling positioning;

3. Laser parallel light tube or beam expansion module: can project near the positive circle of light spots, beam parallelity is high;
 
4. Dot spot module, straight-line module: module light is opened as a plane, and when intersecting with the work surface, a straight line module is used for laser things, laser positioning and various instrument products, including engineering instruments, medical instruments, commercial equipment, etc., can also be used for electrical work;
