Purpose:
A parallel light tube obtains a beam of light from infinity through it, which is called parallel light. It is an important tool for installing, calibrating, and adjusting optical instruments, and is also an important component of optical measuring instruments. With different dividing plates, together with micrometer lenses or microscope systems, it can determine the focal length, discrimination rate, and other imaging quality of the lens group. Fix the attached adjustable plane reflector on the workpiece being inspected in a straight line of motion, and use a Gaussian self aligning lens attached to the light pipe to observe the straightness of the moving workpiece through the Gaussian eyepiece on the light pipe.
