Abstract
A prism used in analysis utilizing surface plasmons is prism of a dielectric medium with a predetermined reflective index. Trapezoidal prism comprises an incident surface on which excitation light is incident from outside, a reflective surface at which the excitation light incident on the incident surface is reflected, an emission surface from which the excitation light reflected by the reflective surface is emitted; and an opposite surface which opposes the reflective surface. The opposite surface is a recessed sink-mark surface.
Claims10
A prism of a dielectric medium used in analysis utilizing surface plasmons, comprising:
- an incident surface on which excitation light is incident from outside;
- a reflective surface at which the excitation light incident on the incident surface is reflected;
- an emission surface from which the excitation light reflected by the reflective surface is emitted;
- and
- an opposite surface which opposes the reflective surface, wherein the opposite surface is a recessed sink-mark surface;
- wherein an injection molding product formed such that the position of a gate, which becomes an entrance port when resin is poured into a mold, is between the center of the thickness direction and the reflective surface;
- and
- wherein the positions to which ejection pins used for releasing the mold are abutted are arranged in a region of the opposite surface other than a first projection region obtained by projecting a gate extension region obtained by extending the gate by the length of the injection molding product in the longitudinal direction of the injection molding product on the opposite surface, and other than a second projection region obtained by projecting a region where the excitation light passes through on the opposite surface.
