What is an easy job to make ultra clear and precise dot projection at various work distances? It is not an easy job to only rely on any prior dot positioning work with a simple laser pointer, sticker or other manual dot alignment too. Under continuous technical innovation of 650nm red laser diode tech and a qualified optic lens, laser tech engineer develops a professional dot measuring tool of a 650nm red dot laser module. It keeps work with high energy density and highly bright red laser light emission, and converts into a ultra bright and precise red reference dot projection at long extending distance. Whenever ultra compact and durable structure made red laser alignment makes proper installation or integration into any other industrial or high tech machine or device, it brings users good direction, easy reaching and no track red dot indication onto multiple working surfaces constantly. 
When dot measuring work with a 650nm red dot laser module is processing for a quite long time, compared with a simple red laser pointer, it should be working for a quite long time and maintaining its ultra clear and stable red laser light and red reference dot projection for a quite long time. For the most important of all, employed by an import 650nm red laser diode within 5mW to 100mW and high power up to 150mW to 500mW, this red dot laser alignment is equipped with a metal heat sink cooling system inside a durable anodized aluminum alloy housing tube. Owing to its proper use of different size tube diameter design, only if it gets superior nice heat dissipation, it just gets increasing laser beam stability, ultra stable and clear red reference dot projection within daily operating time of 10 hours. 
Any time 650nm red dot laser module gets constant electric power source supply, unaffected by long distance or high height, it always makes sure of no barrier, no track and no mistake red dot projection onto any vertical or horizontal surface. Usually it projects a good round shape red reference dot from beam aperture. When dot measuring work is processing at a long distance, it still enables small spot diffusion at long distance within 10 meters. Within wide range operating temperature, and any other mechanical moving or calibration work etc, this red dot laser alignment still maintains highly stable red laser beam and red dot projection, unaffected by overheating and over current impact in long term use. 
Being made with ultra compact size tube design and electric wires extension, with the assistance of a laser alignment mounting bracket, 650nm red dot laser module enables quite easy reaching, noncontact and quick reaching red dot indication. It can be easily mounted onto any industrial and high tech machine or device, without complex equipment debugging requirement. When red alignment laser makes freely adjusted laser dot diameter and dot emitting direction, it brings users low production cost, high stability and long term lasted dot alignment for all measuring fields.
