Abstract

A biological body inspection apparatus includes a measurement module that acquires an amount of light having a wavelength under measurement contained in light incident on the measurement module and an enclosure that accommodates the measurement module and has a window that transmits light traveling toward the measurement module. An adhesive member is provided on a surface of the enclosure at least in an area thereof that surrounds the window. The adhesive member has a light blocking section that is located in an area outside the window and surrounds the window in a plan view in the direction along the optical axis of the light traveling toward the measurement module and blocks light that belongs to a measurement wavelength region within which at least the wavelength under measurement is present.

Claims

1. A spectrometric apparatus comprising:

a measurement module that acquires an amount of measurement light having a measurement wavelength contained in light incident on the measurement module;

an enclosure that accommodates the measurement module and has a window that transmits the light traveling toward the measurement module; and

an adhesive member that is provided on a surface of the enclosure at least in a first area that surrounds the window,

wherein the adhesive member has a light blocking section that is located in a second area in the first area, the second area is located outside the window and surrounds the window in a plan view, and the light blocking section blocks the measurement light, and

the light blocking section further comprises a conductive ground electrode of the spectrometric apparatus.

2. The spectrometric apparatus according to claim 1,

wherein the light blocking section is provided inside an outer circumferential edge of the adhesive member in the plan view.

3. The spectrometric apparatus according to claim 2,

wherein the light blocking section is provided along an outer edge of the window in the plan view.

4. The spectrometric apparatus according to claim 1,

wherein the adhesive member has a light transmissive section that transmits at least the measurement light, and the light blocking section and the light transmissive section are formed integrally with each other.

5. The spectrometric apparatus according to claim 1,

wherein the adhesive member has a light transmissive section that is provided in a position where the light transmissive section overlaps with the window in the plan view and transmits at least the measurement light,

the window has an opening provided in the enclosure and a light transmissive member disposed in the opening, and

the light transmissive section has a refractive index that differs from a refractive index of the light transmissive member by an amount smaller than or equal to a predetermined threshold.

6. The spectrometric apparatus according to claim 1,

further comprising a circuit substrate provided with a controller that controls the spectrometric apparatus,

wherein the light blocking section contains carbon-based conductive fillers so that the light blocking section has conductivity, and

the enclosure has a wiring electrically connecting between the light blocking section and the circuit substrate.

7. The spectrometric apparatus according to claim 1,

wherein the measurement module further includes:

a light source configured to irradiate a subject with light;

a spectroscopic filter configured to select light of a predetermined wavelength from reflected light from the subject so as to transmit the selected light therethrough, and the spectroscopic filter is configured to change a wavelength of the light to be outputted; and

a light reception sensor configured to receive the light from the spectroscopic filter.
