Abstract:
An optical sensor (100) including a semiconductive layer (111), such as a silicon substrate, having an electrical circuit area (111A) and an optical sensing area (111B), preferably comprising a light sensing region (55), such as a multi-junction photodiode, a sample-holding portion (23) over the optical sensing area (111B), a light-guiding structure (130) between the sample-holding portion (23) and the optical sensing area (111B), and an electrical interconnect structure (140), preferably comprising electrical contacts (141) and/or electrical vias (142) and/or electrical layers (143), over the electrical circuit area (111A). The electrical interconnect structure (140) is integrally formed with the light-guiding structure (130), and the light-guiding structure (130) is configured to direct an emitting light (81) from the sample-holding portion (23) to the optical sensing area (111B). The light-guiding structure is designed to prevent light scattering and to direct the emitting light (81) from the sample-holding portion (23) more efficiently the light-sensing region (55) in the optical sensing area (111B). Furthermore, the fabrication of the light-guiding structure (130) complies with the back-end-of-line (BEOL) metallization technology and can be fabricated by the same fabrication process in the same die as the electrical interconnected structure (140) and the multi-junction photodiode of the light-sensing region (55). In addition, the size of the optical sensor can be decreased.

Also provided is a pinhole inspection apparatus for can bodies capable of detecting pinholes with an even smaller diameter by using a high brightness light source. The pinhole inspection apparatus of the present invention includes: a rotating turret having a penetrating through hole; a movable plate provided on a stationary frame opposite the rotating turret; a can body holding member supporting a can body; a photodetector detecting light leaking inside the can body; and a light source irradiating the can body with light. The pinhole inspection apparatus is characterized in that a detour path formed by a pair of shield parts spaced apart a predetermined distance and opposite from each other is provided as a shield mechanism in an entire outer peripheral region of the rotating turret.

The sample carrier (8) can have a substantially planar waveguide (8), wherein the excitation radiation from an illumination unit (1) is coupled into a waveguide edge (10) of the waveguide (8).
Abstract:
The present invention relates to medicine and biology and can be used, in particular, for diagnostic and research purposes to determine coagulation characteristics of blood and its components, as well as in biotechnology, and in fundamental biological research. The object of this invention is to exclude the influence of gas bubbles in the test sample and in the thermostatically controlled fluid on the test process itself (for example, on blood coagulation) and on processing of the registered data, while it has an impact on the test integrity and on accuracy of the obtained results as well as on acquisition of new information on coagulation process and specific parameters thereof. The object is solved by creating a device for monitoring of spatial coagulation of blood and its components comprising: a thermostatically controlled chamber, at least one means of illumination, a means of recording and a means of pressure regulation connected with the thermostatically controlled chamber, wherein the thermostatically controlled chamber includes a cuvette to place a sample of a test medium, a light trap, and is filled with a substance suitable for temperature regulation, and wherein the light trap is formed by geometry of the inner surfaces of the thermostatically controlled chamber, and with a pressure-control means which is connected to the temperature-controlled chamber or to the cuvette.
