Patent number: 7995272Abstract: A fixed focus microscope objective lens designed for high magnification viewing of homogenous specimens. The fixed focus microscope objective comprises a last surface 16 which serves as a specimen mount and enables the device to operate in focus without the need for focus adjustors in the microscope system. The user can observe specimens by simply placing a sample of the specimen on the fixed focus objective lens surface 16. There is no need for preparing a microscope slide, focusing, or positioning the specimen. By eliminating focus and stage adjustors the microscope becomes both simpler to operate and less expensive to manufacture. A fixed focus microscope objective lens can be used by novice microscopists to obtain high quality images at high magnification for nominal cost, and can convert a common video camera into a high quality video microscope.Type: GrantFiled: July 10, 2008Date of Patent: August 9, 2011Inventors: Nicholas E Bratt, Chace H Fadlovich, David W Rush

Patent number: 6972904Abstract: Optical transceivers include a diffractive optical element (DOE) attached to a surface of a prism or other optical support. The DOE is configured to direct an input optical signal to a planar or curved reflective surface, or receive an output optical signal from the planar or curved reflective surface at angles greater than a critical angle in the prism. In some examples, the optical support includes one or more curved reflective surfaces and the DOE is a hologram. Such optical transceivers include a reflective surface that is rotatable with respect to the DOE, or with respect to a selected communication direction and the DOE for selection of a transmission or reception direction. The optical supports of such optical transceivers can be mounted to a window, and include a reflective region configured to total internally reflect optical signals. Selection of a communication direction is based on a rotation of the rotatable reflective surface.Type: GrantFiled: December 9, 2003Date of Patent: December 6, 2005Inventors: Nicholas E. Bratt, Chace H. Fadlovich, Robert M. Pierce

Patent number: 6832859Abstract: An optical fiber assembly includes an optical fiber and ferrule. The ferrule's face is partitioned into several regions. Optical elements can be formed on the regions to diffract light incident on the ferrule. Alternatively, the ferrule's face may have several reflective facets. Light incident on the end of the optical fiber propagates to a communications detector. Light incident on the ferrule's face is redirected to tracking detectors, each arranged to receive the redirected light from a preselected region of the ferrule. The output signals of the tracking detectors are used to adjust the alignment between the incident light and the assembly. Alternatively, tracking fibers or a quadrant cell may be used to directly receive light that would otherwise be incident on the ferrule's face.Type: GrantFiled: February 7, 2002Date of Patent: December 21, 2004Assignee: Terabeam CorporationInventors: John A. Bell, Nicholas E. Bratt, Herman M. Presby, Stuart Ferrier, Mark Lewis Plett
