Abstract:
The invention relates to photometric apparatus and method for determining a characteristic of individual ones of a plurality of samples contained within a plurality of sample chambers. The photometric apparatus includes an enclosure; a substantially uniform source of radiation coupled to the enclosure such that a plurality of sample chambers, disposed within the enclosure, are simultaneously illuminated by the uniform source; and apparatus for detecting an amount of radiation which is transmitted through individual ones of the sample chambers, the detecting apparatus having an output signal having a magnitude which is a function of the amount of radiation which is transmitted through an individual one of the sample chambers. The substantially uniform source of radiation may include at least one source of radiation having an output comprising wavelengths within a first range of wavelengths and an optically integrating sphere having a radiation input port coupled to the output of the source of radiation and a radiation output port coupled to the enclosure. The photometric apparatus may further include radiation directing devices interposed between the radiation output port and the plurality of sample chambers for simultaneously directing radiation emanating from the output port into each of the sample chambers. The directed radiation may be either focussed or collimated.
Abstract:
An apparatus uses a rapid and efficient method for conducting fluorescence measurements, such as immuno assay, of a plurality of samples of a substance using pulsed or continuous light energy, front-end fluorescent optics, a mechanism which allows for lateral and tranverse scanning of rows and columns of wells, and spectra emission analysis of the spectra from the excited samples.
Abstract:
The present invention generally relates to the generation of tunable coloration and/or interference from, for example, surfaces, emulsion droplets and particles. Embodiments described herein may be useful for generation of tunable electromagnetic radiation such as coloration (e.g., iridescence, structural color) and/or interference patterns from, for example, surfaces (e.g., comprising a plurality of microdomes and/or microwells), emulsion droplets and/or particles. In some embodiments, the surfaces, interfaces, droplets, and/or particles produce visible color (e.g., structural color) without the need for dyes.

Abstract:
A method for observing stem cells by an observation device 1 comprises, placing stem cells C in a petri dish 11, mounting the petri dish 11 on a waveguide 21 via water 13, emitting illumination light L1 into the waveguide 21 and emitting the illumination light L1 to the stem cells C in the petri dish 11 via the water 13, and detecting scattered light L2, the scattered light L2 being the illumination light L1 emitted to the stem cells C that is scattered by the stem cells C and has passed through the waveguide 21. Then, in the light image detected by means of the scattered light L2, a region that is markedly darker than other regions is identified as being in the state tending toward differentiation.
