Patents by Inventor Arnold Vainrub

Arnold Vainrub 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).

  • High resolution optical microscope with cardioid condenser for brightfield and darkfield illumination
    Patent number: 7551349
    Abstract: The present invention is an improved illumination system which achieves enhanced spatial resolution and contrast in the observation of small objects. The enhanced performance is achieved by using a metal-halide light source, a power conservative pre-condenser optics train, an annular diaphragm, a cardioid annular condenser, and an adjustable light-filtering iris. These features are also intended to be used with a direct-view light optical microscope. A method of manufacturing and using the improved illumination system is also disclosed.
    Type: Grant
    Filed: December 1, 2006
    Date of Patent: June 23, 2009
    Assignee: Auburn University
    Inventors: Vitaly Vodyanoy, Arnold Vainrub, Oleg Pustovyy
  • Microscope illumination device and adapter
    Patent number: 7542203
    Abstract: The present invention is a dark field illumination system including a light source which is fixed on an entrance slit of a condenser and an objective aligned with the condenser such that the objective and the condenser are adjusted to find a focus spot on a sample. The present invention essentially uses structured illumination to achieve an improved illumination system. The present invention also includes a system and method wherein the objective is coupled to an iris and aligned with the condenser such that when the iris is closed only dark field images are produced, and when the iris is open, direct entrance of light is allowed into the objective and bright field illumination is produced.
