Usually within 1-3 meters dot targeting distance, users are able to obtain the most satisfied dot generation result. At 10cm distance, red dot diameter can be as fine as 0.3mm. At 1 meter working distance, red laser dot can reach 1mm to 2mm owing to existence of laser fan angle. When the working distance is much longer than expected, the projecting red laser dot will become very dim, dark and bigger. It is not able to get a quite satisfied dot generation when dot targeting distance is more than 20 meters.
In some other industrial alignment and collimation working fields, red laser module is also required to make different alignment result such as line and cross line generation work. According to special configuration of line or cross generating glass coated optic lens, it will produce high quality laser line, or cross le line efficiently. In order to make sure of the best quality laser beam emitting, red laser module just adopts the most qualified glass coated cylindrical lens. It is more superior than commonly used glass coated optic lens. Usually this higher configuration made laser alignment tool can project even brighter, and more visible laser line or cross laser line etc. The laser beam quality is even better than expected. Whenever users are making proper selection of required laser alignment tool, users can just obtain the best align result easily.
