In order to make ultra clear and fine enough line indication, including long distance and high lighting occasion, it would be an efficient job to operate a 660nm red laser line generator. Being made with an import 660nm red laser diode and cooling system inside a durable metal housing tube, it enables long time lasting red line projection and high level of beam stability under constant work time of 10 hours per day.

Owing to the use of a qualified glass coated lens within 10 to 110 degree fan angles, cooperated with adjustable focus optic lens, laser line generator allows high transmittance and high energy density red laser light emission. Owing to its low laser beam divergence fan angle and freely adjusted laser line fineness, it enables increasing accuracy and brightness red line measurement for teaching effectively.

Teaching assistance: In the teaching of physics, optics and other courses in school, as a demonstration tool, red laser line can help students understand the optical principles intuitively, such as the rectilinear propagation, reflection, and refraction of light. Teachers can adjust the angle and position of the red laser module so as to show the propagation path and change law of light under different circumstance
