In process of the most precise line alignment at different work distances, it might not be easy to reach with manual line drawing device, but substituting by Berlinlasers 650nm red line laser module. Being made with import 650nm red laser diode and qualified separate crystal lens, it generates high stability red laser light, high uniformity red reference line from laser beam aperture.
Available with wide fan angles of 10 to 93 degree, after correct use of output power and optic lens degree, this 650nm red laser line generator enables high fineness red line emission within 0.5 meter to 6 meters. It allows freely adjusted red line fineness and line emitting direction. It gets only 0.3mm fineness at 10cm, 1mm to 2mm at 2 meters. Unless it is pointing under high lighting, it makes good job for high precision measurement for laser cutting, sand milling, textile garment processing and high tech work etc.
