摘要： An optical system for an ocular optical system or a projection optical system, in which a plurality of illuminating light sources of different colors can be placed in a side-by-side relation to each other, and which makes it possible to reduce the overall size and weight of an apparatus such as a head-mounted image display apparatus or a color film projection apparatus. The optical system has an image-forming optical system (1) that projects a real image or virtual image of an object placed in an image plane (3). The image-forming optical system (1) has an entrance pupil (5) at a position on the side of the image plane (3) remote from the image-forming optical system. An exit pupil (4) is located in a conjugate relation to the entrance pupil (5) with respect to the image-forming optical system (1). A chromatic aberration producing device (6) is provided between the entrance pupil (5) and the exit pupil (4). Even if a plurality of illuminating light sources of different colors are placed in a side-by-side relation to each other on the entrance pupil (5), rays from the different light sources can pass the exit pupil (4), being superimposed on one another, without chromatic aberration.

摘要： An image-forming optical system including a compact and high-performance prism optical system. The image-forming optical system has a prism member formed from a medium having a refractive index larger than 1. The prism member has a first transmitting surface, first to third reflecting surfaces, and a second transmitting surface. The second and third reflecting surfaces are arranged so that the path of the axial principal ray in the prism is folded in a triangular shape, and the axial principal ray incident on the second reflecting surface and the axial principal ray reflected from the third reflecting surface form intersecting optical paths. At least one of the first to third reflecting surfaces has a curved surface configuration that gives a power to a light beam. The curved surface configuration has a rotationally asymmetric surface configuration that corrects aberrations due to decentration.

The distance between the first lens unit and the second lens unit is smaller at the telephoto end than at the wide angle end, and the distance between the second lens unit and the third lens unit changes during zooming from the wide angle end to the telephoto end. The first lens unit consists, in order from the object side, of a front sub lens unit having a negative refractive power, an optical path bending member, and a rear sub lens unit having a positive refractive power. The front sub lens unit includes a biconcave single lens, and the rear sub lens unit includes one or two single lenses.

摘要： The invention provides an optical apparatus enabling diopter adjustment, etc. to be achieved using, for instance, a reflection type variable-optical property optical element or a variable-optical property mirror but without recourse to any mechanical moving part. The variable-optical property mirror 9 comprises an aluminum-coated thin film 9a and a plurality of electrodes 9b. Via variable resistors 11 and a power source switch 13 a power source 12 is connected between the thin film 9a and the electrodes 9b, so that the resistance values of the variable resistors 11 can be controlled by an operating unit 14. The shape of the thin film 9a as a reflecting surface is controlled by changing the resistance value of each variable resistor 11 in response to a signal from the operating unit 14 in such a manner that the imaging capability of the variable mirror is optimized.
