Abstract: A variable-magnification observation optical system includes an objective system, an erecting system, and an eyepiece system. The objective system includes a positive first group, a positive second group, and a negative third group in order from the object side. The eyepiece system includes a positive fourth group and a positive fifth group in order from the object side. The erecting system is located between the first group and the second group. The fifth group includes in order from the object side a negative meniscus lens and a positive lens with an air gap therebetween wherein the negative meniscus lens has a concave surface facing the object. The fifth group has at least one aspheric surface.

Abstract: This infrared optical system using the wavelength range of 3 to 5 μm comprises, in the order from an object side, a first lens having a negative power and formed with a convex meniscus toward an object, a second lens that is convex on both sides, and a cold aperture. A bandpass filter is provided between the second lens and the image surface. The first and second lenses are configured with silicon or germanium with each provided with an aspheric surface at least on one side. The infrared optical system satisfies the conditional expressions: 0.1 μm

Abstract: This aerial image display device is provided with an optical plate having a plurality of reflective surfaces orthogonal to each other in plan view, a projection device, a specular mirror, and a screen. The mirror includes a counter mirror disposed spaced apart from the optical plate at the opposite side of a focused image M across the optical plate. The projection device and the screen sandwich a light path between the counter mirror and the optical plate at the opposite side of the focused image (M) across the optical plate. The projection light emitted from the projection device is incident on the screen after reflecting from the counter mirror, and then incident on the optical plate after reflecting from the screen and then from the same counter mirror.

Abstract: These variable-magnification observation optical systems are provided with an objective system, an erecting system, and an eyepiece system. In order from the object side, the objective system has a positive first lens group, a positive second lens group, and a negative third lens group. In order from the object side, the eyepiece system has a positive fourth lens group and a positive fifth lens group. The erecting system is located between the first and second lens groups. In order from the object side, the fifth lens group has the following, with air gaps in between: a negative meniscus lens element, the concave surface of which faces the object side; a negative meniscus lens element, the convex surface of which faces the object side; and a biconvex positive lens element.
