Descriptions

Internal focusing telescope is a convenient optical examination and adjusting instrument with many usage , which can be used as an autocollimator and a focusing telescope. So it is widely used in optics laboratory and an optical workshop as the test and adjustment tool. For example: It is used to check the guide rail's "straightness", "Verticality" between the base surface, "Parallelism" between the plane, "coaxality" between the apertures, etc.

OElabs offers a large selection of Lasers and Laser
