Disclosed is a bifocal lens constructed such that the lens is not easily damaged when hit by flying fragments and, moreover, able to obtain a consistent focal length with a simple construction. The lens is equipped with a transparent substrate having transparency and rigidity, a transparent resilient body having transparency and elasticity, a transparent fluid enclosed in the space between the aforementioned transparent substrate and the aforementioned transparent resilient body, and a mechanism that induces changes in the shape of the aforementioned transparent resilient body. Changes are induced in the shape of the transparent resilient body to form the desired shape in the two states of the lens which comprises the transparent fluid enclosed in the space between the transparent substrate and the transparent resilient body, making it possible to obtain the desired characteristics (accurate optical characteristics) in either of the two states.

An illumination apparatus includes a reflector including a parabolic or ellipsoidal mirror, a light source arranged near a (first) focal point of the reflector, and a front mirror having a transparent window and a mirror surface symmetrical about the light axis. Luminous flux emitted from the light source is reflected from the reflector. In the case of the parabolic mirror, the front mirror has the same size as an entrance of an output light utilizing optical system, and the luminous flux exits toward the optical system as collimated light. In the case of the ellipsoidal mirror, the front mirror is arranged between two focal points of the ellipsoidal mirror, and the luminous flux is directed toward the second focal point. However, at least one part of the luminous flux is reflected from the front mirror and returned toward the first focal point.
