摘要:
A light emitting reference point is set for a light source attached to a reflecting mirror having an opening on one end thereof, and it is assumed that a point light source is set on the reference point. Then, a reference surface formed as a set of half lines extending from the reference point to an arbitrary point on a front end edge of a socket arranged so as to interrupt rays of light from the point light source. Then, a partial surface of the basic surface of a reflective surface around the socket is arranged so that the partial surface projects more frontward than the reference surface, and a curved form of the partial surface is arranged so that the rays of light emitted from the point reach everywhere on the surface. Then, a group of paraboloids of revolution formed by a number of paraboloids of revolution whose focal distances are different from one another, is prepared, and intersecting lines between the basic surface and the group of paraboloids of revolution are obtained. Finally, a number of reflecting steps are formed on the basic surface between adjacent ones of the intersecting lines. The reflecting steps are defined by parts of the individual paraboloids of revolution.

A reflection mirror has reflection steps formed as portions of respective paraboloids of revolution and disposed between adjacent ones of closed curves formed as lines of intersection of a group consisting of the paraboloids of revolution with different focal distances and a fundamental surface for the reflection surface. The fundamental surface for the reflection surface includes a first curved surface portion and a second curved surface portion connected to the first curved surface portion in the n-th order continuity (N.gtoreq.1). The first curved surface portion is shaped such that when a light beam, which is emitted from a point light source supposed to lie on the principal optical axis of the reflection mirror, is reflected at a reflection point on the first curved surface portion, the light beam reflected thereat is directed substantially parallel to the principal optical axis of the reflection mirror. The second curved surface portion is shaped such that when a light beam, which is emitted from the point light source, is reflected at a reflection point on the second curved surface portion, the light beam reflected thereat is diffused in a given direction.

A blood coagulation analyzer is provided by which, while the measurement using reagent for measuring a Fbg (fibrinogen concentration) is being minimized, the result of a measurement such as a PT measurement can be used to accurately acquire a fibrinogen concentration. The blood coagulation analyzer (1) includes a detector for detecting a transmitted light intensity from a first measurement sample prepared from a blood and a PT measurement reagent; a dFbg acquisition means for acquiring, based on the light detected from the first measurement sample, a dFbg value reflecting a Fbg in the blood; a determination means for determining whether the dFbg value is within a predetermined range or not; a detector for detecting a transmitted light intensity from a second measurement sample prepared from the blood and a Fbg measurement reagent when the dFbg value is outside the predetermined range; and a Fbg acquisition means for acquiring, based on a transmitted light intensity from the second measurement sample detected, a Fbg concentration in the blood sample.
