Abstract:
A biological information detector including a light-emitting part for emitting a light directed at a detection site of a test subject, a light-receiving part for receiving a light having biological information, the light produced by the light emitted by the light-emitting part being reflected at the detection site, a reflecting part for reflecting the light emitted by the light-emitting part or the light having biological information, a protecting part, having a transparent surface in contact with the test subject, for protecting the light-emitting part or the light-receiving part, and a substrate held between the reflecting part and the protecting part, the light-emitting part being positioned on a side of the substrate towards one of either the reflecting part or the protecting part, and the light-receiving part being positioned on a side of the substrate towards another of either the reflecting part or the protecting part.
Abstract:
A biological information detector includes a light-emitting part subjected to emit a first light directed at a detection site of a test subject and a second light directed in a direction other than a direction of the detection site, a first reflecting part subjected to reflect the second light and directing the second light towards the detection site, a light-receiving part subjected to receive light having biological information, where the light produced by the first light and the second light is reflected at the detection site, and a second reflecting part subjected to reflect the light having biological information from the detection site and directing the light having biological information towards the light-receiving part.
Abstract:
To provide a biological information detector or the like in which the detection accuracy or the measurement accuracy can be increased. A biological information detector includes a light-emitting part (14) for emitting light (R1) directed at a detection site (O) of a test subject; a light-receiving part (16) for receiving light (R1′) having biological information, the light (R1′) being light (R1) emitted by the light-emitting part (14) and reflected at the detection site (O); and a contact part (19) formed from a material that is transparent with respect to a wavelength of light (R1) emitted by the light-emitting part (14), the contact part (19) having a contact surface (19A) that makes contact with the test subject and an opposing surface (19B) disposed opposite the contact surface (19A). The light-emitting part (14) is installed on the opposing surface (19B).
Abstract:
A biological information detector includes a light-emitting part, a light-receiving part, a reflecting part, and a substrate. The light-receiving part is for receiving light having biological information, where the light is emitted by the light-emitting part and reflected at a detection site of a test subject. The reflecting part is for reflecting the light emitted by the light-emitting part or the light having biological information. The substrate has a first surface and a second surface facing the first surface, formed from a material that is transparent with respect to a wavelength of the light emitted by the light-emitting part, at least one of the first surface and the second surface of the substrate has a light-blocking region containing wiring leading to at least the other of the light-emitting part and the light-receiving part.
Abstract:
To reduce the effect of directly reflected light on a contact-surface side of a contact member, a biological information detector includes a light-emitting part, a light-receiving part, a reflecting part, a protecting part for protecting the light-emitting part, and a substrate. The protecting member is formed from a material that is transparent with respect to a wavelength of the light emitted by the light-emitting part and has a contact member provided with a contact surface in contact with the detection site. Light emitted from the light-emitting part is inhibited from reflecting once on a contact-surface side of the contact member of the protecting part and being incident on a light-receiving region of the light-receiving part.
Abstract:
A biological information detector includes a first sensor unit for detecting composite information including biological information of a test subject and first noise information originating in external light, having a first light-emitting part for emitting toward there, a first light-receiving part for receiving it including the biological information, reflected there, and the light including the first noise information obtained from the external light, transmitted through there, and a first reflecting and leading part for reflecting the light including the biological and the first noise information, leading it to the first light-receiving part, and a second sensor unit for detecting second noise information originating in the external light, having a second light-receiving part for receiving the light including the second noise information, obtained from the external light and transmitted through there, and a second reflecting, leading part for reflecting the external light and leading it to the second light-receiving part.
Abstract:
A biological information detector includes a light-emitting part for emitting light in an emission wavelength band that includes a wavelength of interest, a light-receiving part for receiving light R1′ having biological information; a reflecting part for reflecting the light R1′ having the biological information at a reflecting surface towards the light-receiving part; and a filter for transmitting the wavelength of interest, the filter being provided between a detection site and the light-receiving part. The filter inhibits light in a wavelength band from a maximum wavelength of incident light to at least a maximum wavelength in the reception wavelength band, and the reflecting surface is configured so that only light having an angle of incidence that is equal to or less than the predetermined angle reaches the light-receiving part.
Abstract:
A microscope objective lens in which a tip and a circumferential portion of a barrel having a plurality of lenses are processed to seal off an inner space containing the plurality of lenses from the outside. The objective lens includes a sealing member that seals a gap between a cap and the barrel when the cap is placed over a rear end portion of the barrel so as to cover an opening formed at the rear end portion.
