G02B17/0636 - CPC Classification

Classification description:

Systems with reflecting surfaces, with or without refracting elements; Catoptric systems, e.g. image erecting and reversing system using mirrors only, i.e. having only one curved mirror using three curved mirrors off-axis or unobscured systems in which all of the mirrors share a common axis of rotational symmetry
