Abstract:
A device for measuring scattered light from a measurement volume with compensation for background signals, includes a light sensor having separately evaluable light-sensitive elements, a single imaging optical system, wherein the light-sensitive elements are arranged in the image plane and the measurement volume is arranged in the corresponding object plane of the optical system, a light transmitter with a collimated light beam, this light-sensitive element detects scattered light from the measurement volume and background light from the overlapping visual ranges behind the subject plane, and the other light-sensitive element detects no or significantly less scattered light from the measurement volume and background light from the overlapping visual areas behind the object plane, and a diaphragm that restricts the visual ranges of the light-sensitive elements behind the object plane.
Abstract:
A fluorescent biological sample operating and monitoring system for restricting the range of movement of a biological sample to facilitate observation. The system includes: a base formed with a predetermined observation position; a shield formed with an operation opening and cooperating with the base to define a light shielding cavity; an infrared illuminating device for illuminating the predetermined observation position; a low-angle excitation light source device including an excitation light source that emits light in a direction oriented toward the predetermined observation position and of a wavelength smaller than that of light emitted by the infrared illuminating device; and an observation display device including an image capturing device having a lens disposed within the shield for capturing an infrared image and oriented toward the predetermined observation position, and an image display.
Abstract:
A light guide member for an object detection apparatus for detecting an object adhered on a light translucent member based on change of quantity of reflection light received from the light translucent member includes a detection face where light exits to the light translucent member and reflection light reflected from the light translucent member enters, the detection face including a detection area where a part of the reflection light to enter the detection unit passes through, and a non-detection area where remaining part of the reflection light not to enter the detection unit passes through; a first intervening member disposed on the detection face attachable to the light translucent member via the first intervening member; and a second intervening member disposed on the detection face attachable to the light translucent member via the second intervening member. The first intervening member has flexibility greater than flexibility of the second intervening member.
Abstract:
A light guide member for an object detection apparatus is devised. The object detection apparatus includes a light source unit, and a detection unit for detecting an object adhered on a surface of a light translucent member based on change of light quantity of reflection light received from the light translucent member. The light guide member includes an incident face where the light exiting from the light source unit enters; a detection face where the exiting light exits to a rear face of the light translucent member and the reflection light reflected from the light translucent member enters; an exiting face where the reflection light exits to the detection unit; and a light guiding portion through which the exiting light and the reflection light proceed. The detection face has curvature corresponding to curvature of the light translucent member.
Abstract:
A nephelometric turbidimeter with a cylindrical turbidimeter vial. The cylindrical turbidimeter vial includes a transparent vial body and a circular optical shielding configured to optically block an inside from an outside of the turbidimeter vial. The vial body comprises a transparent and flat bottom inlet window, and a transparent vial cylinder body. The vial cylinder body comprises a circular outlet window. The optical shielding is arranged axially above the outlet window of the vial cylinder body, over a part of an axial length of the vial cylinder body, and axially adjacent to a non-shielded part of the vial cylinder body which serves as the outlet window.

One embodiment provides an annular optical device, comprising: an annular meso-optic having a substantially triangular cross section and including an annulus centered about an axis of revolution; and a secondary optical structure substantially coaxial within the annulus of the annular meso-optic, wherein the secondary optical structure and the annular meso-optic are separated by a media comprising a media refractive index that is lower than a secondary optical structure refractive index, with the secondary optical structure being configured to hold a specimen to be radiated by impinging electromagnetic radiation directed into the secondary optical structure substantially along the axis of revolution, wherein re-directed radiation from the specimen is allowed into the annular meso-optic by the secondary optical structure if an angle of incidence of the re-directed radiation exceeds the angle of Total Internal Reflectance. Other embodiments are descried and claimed.

Abstract:
A clam-shell luminometer that, when closed, completely encloses an assay reaction mixture-containing reaction vessel and some portion of a reaction carousel or ring. The luminometer includes first and second portions that are coupled to each other, a photomultiplier tube, and plural fiber optic bundles that are optically coupled to the photomultiplier tube. First ends of the fiber optic bundles are disposed adjacent to the reaction vessel in the second portion so that the fiber optic bundles completely surround the perimeter or periphery of the reaction vessel.
