Reinhold Bittner has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Spectral apparatus of the concentric type having a fery prism
    Patent number: 5781290
    Abstract: The conventional grating is substituted by one or more curved prisms in a concentric spectrometer of the type derived from the Offner mirror objective. The curved prisms are known as Fery prisms. The deviations from the concentric form are used as a corrective device. The spectral apparatus is especially suited as an imaging spectrometer having a detector array because the two-dimensional image can be formed in the direction of the spatial coordinate as well as the spectral coordinate without distortions and curvatures.
    Type: Grant

  • Diode-array spectrometer
    Patent number: 5159404
    Abstract: A transparent carrier body of a diode-array spectrometer having a concave grating is configured as a biconvex lens and the diode array is mounted at a distance (d) to a second convex surface lying opposite the concave grating. Preferably, the radii of curvature (r.sub.1, r.sub.2) differ from each other only slightly. A simplified manufacture and adjustment is possible with good optical correction.

    Inventor: Reinhold Bittner
  • Reflecting diffraction grating
    Patent number: 4838645
    Abstract: An unmetallized grating is mounted on an optically transparent body is subjected to radiation which passes through the body and strikes the flanks of the grating grooves at an angle that is larger than the critical angle of the total reflection.

  • Optical arrangement having a concave mirror or concave grating
    Patent number: 4707056
    Abstract: An optical arrangement for imaging a relatively small or slit-like surface is disclosed which includes a concave mirror or a concave grating. Astigmatism is corrected for the concave mirror or concave grating by mounting a slab waveguide at the surface which is to be imaged or at the image which is formed.

  • Wavelength multi/demultiplexer
    Patent number: 4703472
    Abstract: A multi/demultiplexer is disclosed wherein the light-conducting fibers are cemented into a perforated plate made of a photolithographically etchable material, and their terminal faces are ground down and polished together with the surface of the perforated plate. To compensate for focusing differences, a plate of appropriately matched thickness is disposed between the transparent supporting block and the surface of the perforated plate.

  • Objective with aspheric surfaces for imaging microzones
    Patent number: 4655555
    Abstract: The invention is directed to objectives for imaging small regions with a large aperture angle. The objectives include two aspheric bodies made of optically isotropic material wherein the deflection of the light rays is achieved by total reflection on the outer surfaces. The light entry surfaces and light exit surfaces are configured as spherical surfaces having center points at least approximately coincident with the focal points of the aspheric bodies.

  • Method of assembling the optical components of an optical apparatus and a device therefor
    Patent number: 4644632
    Abstract: For mounting the optical components of optical apparatus in an adjusted manner, the optical components are either adjusted and permanently fixed in or on shaped component bodies having accurately defined dimensions, or are produced on such bodies at an accurate location and with accurate alignment. Then, the shaped component bodies are assembled in a defined manner, so that the optical components assume the precisely correct location relative to one another.
