  • Publication number: 20150138625
    Abstract: A projection optical system for use in an image display apparatus having an illumination optical system applying light from a light source, and an image display device receiving the light from the illumination optical system to form a projection image includes a projector lens composed of plural lenses, a first mirror, and a second mirror formed of a concave mirror. The projection optical system is configured to project the projection image onto a projection surface. A projection luminous flux passing through the projector lens to be incident on the first mirror is a luminous flux exhibiting divergence. The projection luminous flux reflected off the second mirror after having reflected off the first mirror is converged once, and the once converged projection luminous flux is projected onto the projection surface. A lens surface of a lens located closest to the first mirror among the lenses of the projector lens is convex.

    Abstract: A microendoscope, and a microendoscopy method related to the microendoscope, each include a tube housing, where an end of the tube housing is shaped and finished to facilitate collection of light emitted from a sample when examined using the microendoscope. In addition, a catadioptric lens assembly, an endomicroscope that includes the catadioptric lens assembly and a microendoscopy method for microscopic analysis that uses the endomicroscope are predicated upon a second element and a third element within the catadioptric lens assembly that each has a dichroic coating. The placement of the dichroic coating on the second element and the third element provides for different magnification factors as a function of illumination wavelength when using the microendoscopy method.

  • Patent number: 9019597
    Abstract: The invention proposes a short-distance front projection system, that is to say with a wide angle, occupying a small volume and offering a possibility of focusing as well a zoom function. It makes it possible to obtain images with a diagonal greater than 2 meters, the whole of the optical system being at least 50 cm from the plane of the image. This projector is constructed on the basis of three optical elements: an ocular, an afocal lens system and a final group forming an objective intended to form the intermediate image in front of the mirror.

  • Patent number: 9019596
    Abstract: A catadioptric projection objective has a first objective part, defining a first part of the optical axis and imaging an object field to form a first real intermediate image. It also has a second, catadioptric objective part forming a second real intermediate image using the radiation from the first objective part. The second objective part has a concave mirror and defines a second part of the optical axis. A third objective part images the second real intermediate image into the image plane and defines a third part of the optical axis. Folding mirrors deflect the radiation from the object plane towards the concave mirror; and deflect the radiation from the concave mirror towards the image plane. The first part of the optical axis defined by the first objective part is laterally offset from and aligned parallel with the third part of the optical axis.
