Automatic substance preparation and evaluation systems and methods are provided for preparing and evaluating a fluidic substance, such as e.g. a sample with bodily fluid, in a container and/or in a dispense tip. The systems and methods can detect volumes, evaluate integrities, and check particle concentrations in the container and/or the dispense tip.

Substance preparation evaluation system

A fine particle measurement device includes a 4f optical system in an optical path that causes a beam spot of a laser output from a light source to form an image with respect to fine particles.

Fine particle measurement device

A fine particle measuring device includes an optical filter that is divided into a plurality of areas and is disposed on an optical path on which light emitted from a fine particle, which is irradiated with light, is guided to an optical detector. In the fine particle measuring device, the optical filter includes a first area having wavelength selectivity by which the first area blocks reflected light from the fine particle and an unnecessary scattered light component and transmits fluorescence, and a second area that is disposed around at least the first area and has no wavelength selectivity so as to transmit a necessary scattered light component.

An optical integrated device includes a light source; a light splitting-and-guiding section that splits a reflected light beam into two end light beams, a connection light beam, and a residual light beam, and guides the two end light beams and the connection light beam in directions different from a direction of the residual light beam; and a light receiving section that receives the two end light beams and the connection light beam with photodetection devices divided, in the tangential direction, into at least two regions within a range in which the connection light beam is incident, receives the residual light beam with photodetection devices divided, in the tangential direction, into regions having widths corresponding to portions on which the two end light beams are incident, and outputs a detection signal in accordance with an amount of light received with each of the photodetection devices.

Optical integrated device, method for detecting light, optical pickup, and optical disc apparatus

An optical pickup includes: a light source; an objective lens; a beam splitter; a quarter wave plate that transforms the optical beam into a circularly polarized optical beam and also transforms the circularly polarized reflection optical beam into an optical beam whose polarization direction is perpendicular to the optical beam; a light detector; a neutral density filter section placed on a mutual optical path of those beams, reducing the intensity of the optical beam while maintaining the intensity of the reflection optical beam; and a filter drive section that puts the neutral density filter section in the mutual optical path or outside of it, wherein the intensity of the optical beam and the filter drive section are controlled such that the amount of the optical beam emitted to the optical disc is maintained at a predetermined level.
