If users are trying to make highly clear dot alignment at various work distances, either it is pointing at close or long distance, it would be an efficient job for users to apply a high brightness and high purity beam emitting tool, such as a 638nm red laser diode module. It is projecting highly visible red laser beam directly from a 638nm red laser diode. It is performing well with the purest and the brightest red laser light from beam aperture. In various industrial and high tech precise dot measuring work fields, only after its correct installation and selection of output power, this red dot laser just achieves high purity red laser light emission and the most precise red dot projection in all application fields constantly.
The primary design of 638nm red laser diode module is paying high attention to its thermal emitting. It is adopting an import 638nm red laser diode as beam emitting source. Comparing with a simple red laser pointer, it should have to work for quite long time, and also maintain good laser beam stability in continuous use. It gets advanced use of a metal heat sink cooling system inside its highly durable anodized aluminum alloy housing tube. When it gets enough space leaving for tube cooling down, this red dot laser has just achieved superior nice thermal emitting and highly reliable and stable red reference dot projection within constant work time of 8 to 10 hours per day.
According to the use of AC/DC adapter, without spending extra time on battery change, this 638nm red laser diode module always makes continuous red laser beam and red dot indication onto various working surfaces. It is applying for various working environments, and also accepting wide range electric current of 100V to 240V. In occasion that it selects correct operating voltage of 5V, 9V 1000mA DC power supply, this red dot laser has just assured continuous red laser beam emission, and highly clear and stable red dot alignment within constant work time of 8 to 10 hours per day.
Whatever kind of working surface it is pointing, being made with 16mm and 26mm diameter tube, this 638nm red laser diode module has just assured the most convenient installation, and easy red dot generation onto various working surfaces. It is operating easy and quick as an accessory part. Every time it makes freely adjusted dot diameter and red dot projecting direction, and proper wearing of laser safety goggles, high power red dot laser still makes easy and highly clear red dot measurement at various work distances perfectly.
