G02B17/0626 - 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

Sub-classes:

G02B17/0631 » {on-axis systems with at least one of the mirrors having a central aperture} 16
G02B17/0636 » {off-axis or unobscured systems in which all of the mirrors share a common axis of rotational symmetry} 23
G02B17/0642 » {off-axis or unobscured systems in which not all of the mirrors share a common axis of rotational symmetry, e.g. at least one of the mirrors is warped, tilted or decentered with respect to the other elements} 68
