摘要： An infrared lens unit includes, in order from the object side, an aperture, a lens group, and a band-pass filter which passes a light beam of a prescribed wavelength band of the infrared region. The lens group further includes, in order from the object side, a first meniscus lens which has a positive power and is convex on the object side, a second meniscus lens which has a positive power and is convex on the image side, and a convex lens which has a positive power and is convex on the object side. The lens group further includes a near-telecentric state on the image side, wherein the angle of entry of the light beam into the band-pass filter is either 0° or close to 0°. Thus, it is possible to accurately pass a light beam of a prescribed wavelength band of the infrared region by the lens unit.

摘要： A projection lens system (G1, G2) includes a front group (G1) disposed on a projection-plane (SC) side, a rear group (G2) disposed on a display-surface (SF) side of an image display element inclined with reference to the projection plane (SC), and an aperture stop (S) disposed on the display-surface (SF) side with reference to the front group (G1). The rear-group optical axis is tilted on the shared plane at a tilt angle ξ with reference to the display-surface normal. In projection lens system (G1, G2), when the amount of shift Δ is zero, the tilt angle ξ satisfies a conditional expression 0
