The inner tube of 635nm red line laser module is applying qualified glass coated lens. It is projecting high quality and high fineness red line. When it is trying to make continuous line alignment, it just passes through quite strict laser beam stability tests and special use of glass window. The genuine operation gets no appearance of laser light decay or blur, but also enables freely selected fan angles of 10 degree to 110 degree. Only if this laser line generator selects correct optic lens degree and makes proper beam focus adjustment, it makes sure of no mistake and no barrier line alignment in all occasions effectively.
