Abstract:
The present invention provides a culture vessel and microscope that allows a wide area of favorable observation of the sample in the plural wells even when a negative refractive power is generated in the culture medium, wherein a ring-shaped opening, a condenser lens, a lens array, a well plate, an objective lens and a phase contrast plate are disposed in this order viewed from the light source side with a construction to place a phase contrast film of the phase contrast plate in a conjugated relation to the projection pupil position or projection pupil of the objective lens, and the culture vessel is constructed of the lens array and well plate with a relative disposition in which the optical axis of each lens is coaxial with the center line of the confronting each well; the aperture of the ring-shaped opening being smaller than the aperture of the ring-shaped opening that is used when the culture vessel is not disposed in the optical path.
Abstract:
In a spectrophotometer, each of a plurality of source optical fibers is selectively receptive of source radiation and carries the radiation to a corresponding selected liquid sample cell. A corresponding return optical fiber returns transmitted radiation from the sample to a polychromator. For selecting a sample, a switching member holds exposed ends of the optical fibers on a circle coaxial with an axle for rotating to selected positions. Respective optical trains in the instrument direct radiation into and out of the selected pair of fibers. The diameter of a source aperture, the spacing of the aperture from the radiation source, and the source area define a source etendue. The optical fibers have a fiber etendue substantially the same as the source etendue.
Abstract:
There is described a unique instrument system employing a laser, having a polarized and collimated beam of radiation, which is split into a multitude of primary and secondary beams containing the same desirable properties of high collimation and monochromaticity. The secondary beams are used to measure simultaneously multiple antigen-antibody (Ag-Ab) agglutinations reactions involving latex particles.

Abstract:
Techniques are described for the detection of multiple target species in real-time PCR (polymerase chain reaction). For example, a system comprises a data acquisition device and a detection device coupled to the data acquisition device. The detection device includes a rotating disk having a plurality of process chambers having a plurality of species that emit fluorescent light at different wavelengths. The device further includes a plurality of removable optical modules that are optically configured to excite the species and capture fluorescent light emitted by the species at different wavelengths. A fiber optic bundle coupled to the plurality of removable optical modules conveys the fluorescent light from the optical modules to a single detector. In addition, the device may control the flow of fluid in the disk by locating and selectively opening valves separating chambers by heating the valves with a laser.
