A blood coagulation analyzer and analyzing method perform following: (a) preparing a measurement specimen by dispensing a blood specimen and a reagent into a reaction container; (b) emitting light of a plurality of wavelengths to the measurement specimen in the reaction container, the wavelengths comprising a first wavelength for use in a measurement by a blood coagulation time method, and at least one of a second wavelength for use in a measurement by a synthetic substrate method and a third wavelength for use in a measurement by an immunoturbidimetric method; (c) detecting light of a plurality of wavelengths corresponding to the light emitted in (b), from the measurement specimen, by a light receiving element, and acquiring data corresponding to each wavelength; and (d) conducting an analysis based on the data corresponding to one of the wavelengths among the acquired data, and acquiring a result of the analysis.

A light condensing device for inspecting the quality inside fruits and vegetables, resolving problems in which manually holding fruits for inspection is inefficient and cannot be used in large-scale fruit packaging production. The device comprises a housing, a halogen lamp, a diaphragm, a plano-convex lens support a first plano-convex lens, a reflector lens fixing plate, a reflector, a plano-convex lens fixing plate, and a second plano-convex lens. The housing is a sealed and non-transparent housing. The halogen lamp is fixedly disposed at a left end of the housing, and extends into an inner portion of the housing. A pluggable diaphragm is disposed at the right side of the halogen lamp, and is used to guide a lighting direction of the halogen lamp. The diaphragm passes through the inner portion of the housing. The plano-convex lens support is fixedly disposed inside the housing at the right side of the diaphragm.

An inspection apparatus for inspecting a flow of particulate material, comprising: a background reflector (105) adjacent which in use falls a flow of particulate material (F); and a lighting unit (107) for illuminating an elongate viewing field (VF) across the background reflector (105), the viewing field (VF) having a first width (w.sub.1); wherein the lighting unit (107) comprises a fixed, non-scanning light source (115), and the light source (115) is formed of one or more light elements (120) which define a second width (w.sub.2) which is shorter than the first width (w.sub.1) of the viewing field (VF).

The invention provides a spectroscopic instrument, which comprises a projecting optical system for projecting a projecting light emitted from a light source, a photodetecting optical system for receiving a reflection light from an object to be measured and for guiding to a photodetection member, and a spectroscope for detecting a condition of the object to be measured based on the reflection light as received by the photodetection member, wherein the projecting optical system and the photodetecting optical system have a projecting system chromatic aberration decreasing component and a photodetecting system chromatic aberration decreasing component which eliminate chromatic aberrations, respectively.
