In a spectroscopic module, a light shielding member is disposed between a plurality of bandpass filters and a light detector. The light shielding member includes a plurality of wall portions. The plurality of wall portions are arranged along an X direction with a light passage opening interposed therebetween, each of a plurality of optical paths from the plurality of bandpass filters to a plurality of light receiving regions passing through the light passage opening. A first wall portion and a second wall portion adjacent to each other among the plurality of wall portions are in contact with the bandpass filter, the bandpass filter corresponding to the light passage opening between the first wall portion and the second wall portion. A width in a Y direction of the light passage opening is larger than a width in the Y direction of the bandpass filter.

Wearable spectroscopy systems and methods for identifying one or more characteristics of a target object are described. Spectroscopy systems may include a light source configured to emit light in an irradiated field of view and an electromagnetic radiation detector configured to receive reflected light from a target object irradiated by the light source. One or more processors of the systems may identify a characteristic of the target object based on a determined level of light absorption by the target object. Some systems and methods may include one or more corrections for scattered and/or ambient light such as applying an ambient light correction, passing the reflected light through an anti-scatter grid, or using a time-dependent variation in the emitted light.

A modular housing for a spectrometer, the housing comprising at least two modules, the housing further comprising: a sensor recess configured to receive a sensor, the sensor being configured for determining at least one light spectrum characteristic of light received after optical interaction of the light with a sample; an aperture configured for receiving and guiding the light received after the optical interaction along a reception path extending from an entrance of the aperture to the sensor recess; and at least two channels configured for guiding and emitting light out of the modular housing, such that the light, after the optical interaction with the sample, is received at the entrance of the aperture; wherein the at least two channels are arranged along intersecting or skew axes; and wherein at least two of the at least two modules comprise respective ones of the at least two channels.

A colorimetric apparatus has a shutter unit that can shift between a closed position and an open position. The apparatus body has: a shifting member that can shift between a projection position, at which the shifting member projects in a first direction, and a retraction position, at which the shifting member retracts in a second direction; a first pressing member that presses the shifting member in the first direction; and an operation conversion means that converts the shift operation of the shifting member with respect to the apparatus body to the shift operation of the shutter unit. In a state in which the shifting member is at the projection position, the shutter unit is at the closed position. When the shifting member shifts from the projection position to the retraction position, the shutter unit shifts from the closed position to the open position.

A multispectral sensor array can include a combination of ranging sensor channels (e.g., LIDAR sensor channels) and ambient-light sensor channels tuned to detect ambient light having a channel-specific property (e.g., color). The sensor channels can be arranged and spaced to provide multispectral images of a field of view in which the multispectral images from different sensors are inherently aligned with each other to define an array of multispectral image pixels. Various optical elements can be provided to facilitate imaging operations. Light ranging/imaging systems incorporating multispectral sensor arrays can operate in rotating and/or static modes.

An electronic device may include a light sensor system. The light sensor system may have a light source that emits light and a light detector that receives the emitted light after the emitted light has interacted with an external object. The light source may include a ring of light-emitting diodes or other light-emitting devices surrounding the light detector or may have light-emitting devices that are surrounded by a ring-shaped light detector. Polarizer structures may be incorporated into the light sensor system. Control circuitry in the device may control the light source so that different polarizations of light are emitted at different times. The control circuitry may process signals from the light detector that are gathered under different polarizations to discriminate between specular and non-specular reflections from the external object.

There is provided a module package including a substrate, a photo sensor chip, a molded transparent layer and a glass filter. The substrate has an upper surface. The photo sensor chip is attached to the upper surface of the substrate and electrically connected to the substrate. The molded transparent layer covers the photo sensor chip and a part of the upper surface of the substrate, wherein a top surface of the molded transparent layer is formed with a receptacle opposite to the photo sensor chip. The glass filter is accommodated in the receptacle.

A method, system, apparatus, and/or device to determine a condition of a user using a wearable device with a miniaturized spectrometer. The method, system, apparatus, and/or device may include: a band configured to extend at least partially around a body part of a user, the body part comprising an internal feature within the body part; a light source embedded in the band, where the light source is configured to emit light into the body part as the user wears the band; a collimator; an optical filter; and an optical sensor, where the collimator, optical sensor, or the optical filter are arranged together to form a stack embedded in the band.

A spectroscopic module includes a plurality of beam splitters that are arranged along an X direction; a plurality of bandpass filters disposed on one side in a Z direction with respect to the plurality of beam splitters facing the plurality of beam splitters, respectively; a light detector disposed on the one side in the Z direction with respect to the plurality of bandpass filters and including a plurality of light receiving regions facing the plurality of bandpass filters, respectively; a first support body supporting the plurality of beam splitters; and a second support body supporting the plurality of bandpass filters. The second support body includes a support portion in which a support surface is formed so as to be open to the one side in the Z direction. The plurality of bandpass filters are disposed on the support surface.

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.
