Either line aligning work is processing at close or long distance, it makes good job with a moderate brightness device, such as a Berlinlasers 650nm red line laser module. It projects moderate brightness red laser light directly from a 650nm red laser diode within 5mW to 100mW. On basis of easy use of a metal heat sink cooling system and AC/DC adapter, it always leaves enough space for tube cooling down, but also assures highly stable red line alignment within constant work time.
The advanced use of qualified glass coated lens within 10 to 110 degree is cooperating with a glass window. This 650nm red line laser module is generating no decay light and high linear quality red line within 0.5 meter to 6 meters. It allows freely adjusted line fineness and line emitting direction. Within freely installed distance of 3 meters, this laser line generator assures no barrier and low cost line alignment for industrial and high tech work fields perfectly.
