Available with wide range output power of 5mW to 100mW, in long lasting dot measuring work fields, this 650nm red laser diode module is requiring to work for quite long time. Being made with an import 650nm red laser diode, different from a simple red laser pointer, it always equips with even better thermal emitting. For instance, after the use of a metal heat sink cooling system, it is always working well with at least 3 times better thermal emitting than formal air or water cooling system. In addition, in process of long lasting red dot alignment within 8 to 10 hours, only after leaving enough time and space for tube cooling down, it maintains highly stable and no decay light red dot emission in continuous use.
