A spectroscopic detector comprises a first housing, a second housing, a camera lens housed in the first housing, and an image sensor housed in the second housing. The first housing has a first through hole formed therein. The second housing has a second through hole formed therein. The second housing is attached to the first housing so as to allow for communication between an inside of the second housing and an inside of the first housing via the first through hole and the second through hole. In a state where the second housing is attached to the first housing, a periphery of the second through hole is located inside a periphery of the first through hole.

An infrared spectrometer for operation in the mid-infrared spectral range is presented, where the spectrometer includes a Bragg-mirror-based spectral filter that is operative for providing an interrogation signal whose spectral content is dispersed along a first direction at a filter aperture. The filter aperture is imaged through a sample by a thermal-imaging camera to create a focused image that is based on the interrogation signal and the absorption characteristics of the sample. As a result, embodiments in accordance with the present disclosure can be smaller, less complex, and less expensive than infrared spectrometers known in the prior art.

A remote sampling sensor for determining characteristics of a sample includes measurement optics and an insertion probe. The measurement optics are configured to emit light and detect returned light. The insertion probe includes a chamber, the chamber being configured to permit the sample to enter the chamber, an insertion tip at a distal end of the insertion probe, and a retro-reflective optic adjacent the insertion tip. The retro-reflective optic is configured to return the light from the measurement optics through the chamber to the measurement optics. The insertion probe is configured to be remotely located from the measurement optics.

A downhole tool has a tool body with an outer diameter equal to a borehole diameter, at least one cavity formed in and opening to an outer surface defining the outer diameter of the tool body, a light source, a filter, and a light detector mounted in the at least one cavity, and a window disposed at the opening of the at least one cavity, wherein the window encloses the cavity.

An electronic device includes a housing that houses a movable member inside the housing, and a shock absorbing member that reduces a shock to the movable member. The shock absorbing member holds the housing on an inner side of the shock absorbing member and includes at least one of a protrusion protruding in a direction along a movable direction of the movable member or a depression depressed in a direction along the movable direction on an outer side of the shock absorbing member.

Disclosed herein is an electronic apparatus and method capable of identifying a state of an object. The electronic apparatus includes a light-emitting diode array configured to transmit light beams having different wavelengths, a photodiode array configured to receive the light beams, a display, and a processor configured to control the light-emitting diode array to transmit the light beams having the different wavelengths toward an object, identify a state of the object based on intensities reflected on the object according to the light beams having the different wavelengths that are received by the photodiode array, and display information about the state of the object on the display.

A spectrometer comprises a plurality of isolated optical channels comprising a plurality of isolated optical paths. The isolated optical paths decrease cross-talk among the optical paths and allow the spectrometer to have a decreased length with increased resolution. In many embodiments, the isolated optical paths comprise isolated parallel optical paths that allow the length of the device to be decreased substantially. In many embodiments, each isolated optical path extends from a filter of a filter array, through a lens of a lens array, through a channel of a support array, to a region of a sensor array. Each region of the sensor array comprises a plurality of sensor elements in which a location of the sensor element corresponds to the wavelength of light received based on an angle of light received at the location, the focal length of the lens and the central wavelength of the filter.
