Not the same a simple red laser pointer and only limited by close distance and formal hand reaching places, it is always making good job with a formal brightness beam emitting tool, such as a 660nm red laser diode module. It is not as bright as a 635nm red laser device. However, after its advanced use of glass coated lens and constant power source supply, this direct emission made device of 660nm red dot laser is performing well with high intensity red laser light emission, and highly clear red dot alignment at various work distances.

From the very beginning design of 660nm red laser diode module, it has been made with good thermal emitting system. It is in need to make continuous dot alignment onto various working surfaces. According to special use of a metal heat sink cooling system, it always gets even better thermal emitting than formal air or water cooling system. When it applies 660nm red laser diode within 5mW to 100mW, after its proper configuration of 16mm and 26mm diameter anodized aluminum alloy housing tube, this direct diode emission made red dot laser always gets excellent thermal emitting, and highly reliable red reference dot projection within constant work time of 8 to 10 hours per day.
According to the use of an external AC/DC adapter, without spending extra time on alkaline battery power source, this 660nm red laser diode module is able to make continuous red laser beam emission. It is also leaving even larger space for tube cooling down. In occasion that different output power made 660nm red dot laser is equipping well with 5V, 9V 1000mA DC power supply, it is not only projecting highly visible red laser beam at several miles far away, but also making quite satisfied dot alignment within wide range work distances and other formal lighting working occasions as well.
Whatever kind of working surface it is pointing, without serious relying on any manual labor force input, this 660nm red laser diode module always makes easy and quick red dot indication. It is also assuring no track and no barrier red reference dot projection for all precise device manufacturing work fields. The special use of APC, ACC driving circuit board just makes perfect protection of itself from increasing temperature and serious electric current impact as well. When 660nm red alignment laser makes constant red dot projection within 8 to 10 hours per day, after correct wearing of laser safety goggles and avoiding eye exposure to beam aperture, it just assures easy and safe use in all application fields perfectly.
