Patent number: 7733584Abstract: An optical device includes an elongated tube configured for insertion into a body and optical members located in the tube. The optical members are configured to have an optical invariant-to-clear aperture semidiameter ratio greater than about 0.05 and an optical path difference less than about a value of the optical invariant divided by at least 250 times a midrange wavelength in a spectral range from about 435.8 nm to about 656.3 nm, and are preferably formed of an extraordinary dispersion optical material. A method includes conducting polychromatic light through at least one optical member located in an elongated tube configured for insertion into a body, where the optical members have an optical invariant-to-clear aperture semidiameter ratio greater than about 0.05 and an optical path difference less than about a value of an optical invariant divided by at least 250 times the midrange wavelength from about 435.8 to about 656.3 nm.Type: GrantFiled: May 4, 2007Date of Patent: June 8, 2010Assignee: Smith & Nephew, Inc.Inventor: Yuri Kazakevich

Patent number: 6749561Abstract: An endoscopic apparatus and method allow for robust autofocusing operation regardless of contrast characteristics of the environment. The endoscopic apparatus and method can focus on a field stop edge and store default information of the apparatus focused on the edge. Later, if the endoscope fails to focus on an internal target object during the course of normal operation, the endoscope recalls the default information from memory to focus the lens on the edge of the field stop. Thus, internal structural objects in front of the endoscopic apparatus are brought into reasonable focus for visualization.Type: GrantFiled: August 23, 2001Date of Patent: June 15, 2004Assignee: Smith & Nephew, Inc.Inventor: Yuri Kazakevich
