    摘要： An IR imaging system is presented comprising an optical assembly comprising an optical assembly with a lens housing made of an organic polymer, the housing structurally defining a frontal aperture stop having an object-side surface and a detector-side surface, characterized in that the aperture stop comprises a metallic diaphragm. This results in an affordable design, well suited to be build into portable or mobile devices, in particular when protected behind an IR-transparent window.

    摘要： Aspects of the present invention provide dynamic focusing systems and dynamic zoom systems having no moving parts. The dynamic focusing systems can include an electro-active lens, a fixed focus lens in optical communication with the electro-active lens and a focal plane. The dynamic zoom systems can include a first electro-active lens, a second electro-active lens, a fixed focus lens, and a focal plane. The electro-active lenses of the present invention can have an adjustable optical power to provide variable focusing capability. The dynamic focusing systems and dynamic zoom systems can include a controller for altering the adjustable optical powers of the electro-active lenses. The dynamic focusing systems can focus on objects at various distances based on the controlled optical power of the included electro-active lenses. The dynamic zoom systems can provide magnification and de-magnification based on the controlled optical power of the included electro-active lenses.

    摘要： Disclosed is an image pickup lens (LN) including at least three lens blocks (BK) each equipped with a lens substrate (LS) being a parallel flat plate, and a lens or lenses (L) having a positive of negative power and being connected to at least one of an object-side surface and an image-side surface of the lens substrate (LS). In the image pickup lens (LN), a first lens block (BK1) arranged at a closest position to an object side has a positive powder, a second lens block (BK2) arrange at an image side of the first lens block (BK1) has s negative power, and predetermined conditional expressions are satisfied, whereby the image pickup lens capable of being easily produced at a low cost and having a high performance and a compact size can be provided.

    摘要： An image capture lens includes, in order and from a side of an object, a first positive lens having a convex surface facing the object, an aperture diaphragm, a second negative lens having a convex surface facing an image, a third positive lens having a concave surface facing the image, and an IR cut filter. The three lenses, aperture diaphragm, and IR cut filter are formed of resin materials, all the lens surfaces except for the IR cut filter are aspheric, and Conditional Equations (A0) to (A2) are satisfied.
