If users are trying to make fine and clear line alignment at different work distances, it is operating easy and quick with a Berlinlasers 650nm red line laser module within 5mW to 100mW. The advanced use of a metal heat sink cooling system and APC, ACC driving circuit board are cooperating with 16mm and 26mm diameter metal housing tube.
This red laser line generator adopts qualified glass coated lens within 10 to 110 degree. It is cooperating with a glass window, which is working well with highly clear and stable red line alignment in long lasting use. Only if there is enough space for tube cooling down, 16mm or 26mm diameter tube made laser device just makes sure of high stability line alignment for laser cutting, sand milling, lumber machine, textile garment processing and high tech work etc.
