    摘要： A disclosed optical apparatus comprises an optical unit including a light entrance surface, light reflecting surfaces and a light exit surface all of which are integrally formed of transparent material, and the optical unit has in its interior an internal refracting surface for refracting light. Since a light beam passes through the optical unit from the light entrance surface to the light exit surface via the internal refracting surface and the light reflecting surfaces along a bent optical path, the optical apparatus is reduced in size and improved in optical performance, particularly, well corrected in chromatic aberration. Another disclosed optical apparatus is arranged to achieve zooming by using a plurality of optical units each of which is similar to the aforesaid optical unit.

    摘要： A zoom optical system and an image pickup apparatus using the same are disclosed. The zoom optical system comprises a first optical unit having a refractive power, the first optical unit having a reflecting surface, a second optical unit having a refractive power, and a driving portion for moving a light receiving surface which receives light from an object through the first optical unit and the second optical unit. The zoom optical system performs variation of magnification by moving at least one of the first optical unit and the second optical unit, and a deviation of a focus position due to the variation of magnification is corrected by the light receiving surface being moved by the driving portion.
