Patent number: 9006687Abstract: A first lens configured to convert light from the objective lens into parallel light includes a concave lens part having a concave curved face in a center portion of a flat face, and a convex lens part having a convex curved face around a flat face. Further, the first lens includes first and second regions configured to diverge light through the flat face and the concave curved face and a third region configured to collect light through the convex curved face and the concave curved face. When the sample is on a sample table and sealed in a two-dimensional electrophoresis substrate, light totally reflected by a side surface of the objective lens enters the second region. In contrast, when the sample is directly on the sample table, the light enters the third region.Type: GrantFiled: February 20, 2013Date of Patent: April 14, 2015Assignee: Sharp Kabushiki KaishaInventor: Yukio Watanabe

Publication number: 20150028226Abstract: Even when the distance from an objective lens to a sample differs, the distribution of light from the sample can be detected accurately. A first lens 23 for converting light from the objective lens into parallel light is composed of a concave lens part 32 having a concave curved face 32c in a center portion of a flat face 32a, and a convex lens part 33 having a convex curved face 33c around a flat face 33b. Further, the first lens 23 includes first and second regions for diverging light through the flat face 33b and the concave curved face 32c and a third region for collecting light through the convex curved face 33c and the concave curved face 32c. When the sample is placed on a sample table while being sealed in a two-dimensional electrophoresis substrate, light totally reflected by a side surface of the objective lens is caused to enter the second region. In contrast, when the sample is directly placed on the sample table, the light is caused to enter the third region.Type: ApplicationFiled: February 20, 2013Publication date: January 29, 2015Applicant: Sharp Kabushiki KaishaInventor: Yukio Watanabe

Publication number: 20150008338Abstract: Sensitivity is increased by enhancing the fluorescence collection efficiency while suppressing the increase in size of an objective lens. An objective lens 17 is structured to have a convex lens part 26 in a center portion and to have a truncated conical cylindrical body 27 around the convex lens part 26. Therefore, a fluorescence component b having too wide an emission angle to fit in the convex lens part 26, of fluorescence emitted from a sample 16, can be collected by total reflection on an outer peripheral surface 27b of the cylindrical body 27. Thus, even light having too wide an emission angle to be collected by a normal convex lens can be collected. As a result, it is possible to suppress the increase in size of the objective lens, to enhance the fluorescence collection efficiency, and to prevent the S/N ratio from being decreased by the existence of undetected fluorescence that is blocked by a prism 20. This can realize a fluorescence information reading device having high sensitivity.Type: ApplicationFiled: November 29, 2012Publication date: January 8, 2015Inventor: Yukio Watanabe
