When you are first time to make dot measurement with a economy red dot laser alignment, you will find that it is just a quite nice and low production cost solution for users to select it. It is making the best use of 650nm red laser diode tech, owing to its quite long development and mature laser diode tech application, this red laser module is just able to get highly stable and reliable red reference dot targeting in long term use. In addition, only according to quite easy screw of laser beam aperture part, red laser beam is temporarily focused, and then obtaining a highly accurate and small size red dot on different working surfaces effectively.
In order to make sure of easy installation and good performing in multiple working fields, economy red dot laser alignment is using high duration aircraft used aluminum alloy housing material and copper raw material made 650nm red laser diode as its core part, in various industrial precise machinery processing works, this red laser module is just able to get high laser beam conductivity. Under formal industrial dot measuring works, it is also bearing harsh working occasions, such as strong interference and strong static, and keeping highly stable red alignment laser dot targeting within 8 to 10 hours a day.
When 650nm red laser diode is getting mass production, once it is made into a real dot measuring tool such as economy red dot laser alignment, it is just able to get quite low production cost. Only after its easy connect with a DC input power supply, it begins to generate constant red reference dot on various working surfaces. Although sometimes this alignment laser is being used with quite high power up 50mW to 100mW, in order to avoid eye damage caused by powerful red laser light, it is just a necessity for user to wear a pair of laser safety goggles until getting no danger user perfectly.
