What I know is that usually higher output power laser alignment can always get larger size light spot in operation. Owing to its existence of laser fan angle, the projecting red reference dot might become very large at very long operating distance. As a result, when users want to get a small size lights spot more than 20 meters in distance, it is obvious not an easy job to do so. In addition, the maximum targeting distance of red laser alignment dot should not exceed 30 meters. When the targeting distance is longer than 20 meters, the light spot might become extremely larger in operation. At 20 meters working distance, the projecting red dot from pro red dot laser alignment can reach about 5 mm to 8 mm. In such working distance, this kind of dot measurement tool is workable for making red light spot with dimension of about 10 mm.
Before the time I have made decision to choose red dot laser alignment, I have no understanding of any laser tech applied laser gadget, even this dot measurement tool. But it should be a quite successful selection of this dot measurement tool for my work.
When I am using this pro red dot laser alignment for long distance dot generation work, I only need to adjust its targeting red light spot on required working surfaces. In order to make dot projection very stable and reliable in continuous dot measurement work, it is necessary to make it fixed on machine or equipment with a mounting bracket. While it is being mounted on devices, the projecting dot will become especially stable and accurate. This advanced dot measurement tool has just made my worker interesting and efficient. Whatever operating occasions, this advanced designed industrial alignment laser has just made dot projection more easily and accurately.
