This green dot laser alignment tool is totally different from finger, sticker or laser pointer. Whatever kind of working occasions, it can just make long time continuous dot generation in practical use. Usually it has no limitation of targeting distance or height. Users always only need to find the most proper position and let alignment laser fixed so as to assure quite stable and reliable dot generation. In laser marking fields, this operation of this green dot laser alignment can always help operators make the most accurate dot positioning on processing material. It has just provided workers easy targeting and convenient dot positioning in work.
For the most important of all, users should choose the most appropriate output power. When users are marking dot generation with green dot laser alignment, users should always make correct selection of required output power. For room working condition, usually a 5mW green laser alignment is enough. In room dot generation work, low powered alignment laser is recommended. For long distance dot generation work, users have to choose high powered alignment laser so as to assure bright and visible enough dot generation in operation.
It is also very important to know enough about required dimension of light spot. When users are making close distance dot generation within 1 meter, usually the size of targeting green dot emitting from green laser alignment is within 1mm to 3mm. However, when targeting distance is more than 20 meters or even longer, the targeting green laser dot will become 20mm or even larger.
In order to make dot measurement from this green laser alignment more accurate and precise, it is always specially designed with adjustable focus. Usually get easily beam focused green light spot on targeting surfaces according to constant adjustment of its head part.
