Abstract: A spectral camera for producing a spectral output is disclosed. The spectral camera has an objective lens for producing an image, an optical duplicator, an array of filters, and a sensor array arranged to detect the filtered image copies simultaneously on different parts of the sensor array. Further, a field stop defines an outline of the image copies projected on the sensor array. The filters are integrated on the sensor array, which has a planar structure without perpendicular physical barriers for preventing cross talk between each of the adjacent optical channels. The field stop enables adjacent image copies to fit together without gaps for such barriers. The integrated filters mean there is no parasitic cavity causing crosstalk between the adjacent image copies. This means there is no longer a need for barriers between adjacent projected image copies, and thus sensor area can be better utilized.

Abstract: A spectrometer comprises a package having a stem and a cap, an optical unit arranged on the stem, and a lead pin penetrating through the stem. The optical unit has a dispersive part for dispersing and reflecting light entering from a light entrance part of the cap, a light detection element for detecting the light dispersed and reflected by the dispersive part, a support for supporting the light detection element such as to form a space between the dispersive part and the light detection element, a projection projecting from the support, and a wiring electrically connected to the light detection element. The projection is arranged at such a position as to be separated from the stem. The lead pin is electrically connected to the second terminal part while being disposed to the projection.

Abstract: 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.

Abstract: A small scale and low cost spectral sensing system designed primarily for multi-component fluids that provides a compact, low cost platform for analyzers or chemical sensors with limited number of optical and mechanical components featuring a light source, an optical interface with the sample, and a custom detector (multi-element). A single detector element has a specific wavelength, defined by a filter that can be used to select and measure specific chemical compounds. Multiple detector elements are combined to create a multi-channel detector capable of measuring a broad range of wavelengths from ultraviolet (UV) to near and mid-infrared wavelengths. The fabricated sensor can be configured for almost any class of material including gases, vapors, and liquids, with extension to solids. This is linked to the use of the custom detectors featuring filters tailored to specific substances in a broad spectral range from the UV to infrared.

Abstract: Exemplary apparatus for method for forming at least one spectral encoding endoscopy configuration. For example, it is possible to modify a spacer configuration and an lens optics configuration to have respective predetermined lengths, and also to modify a dispersive optics configuration to have a further predetermined length. Further, the modified spacer and modified lens optics configurations can be attached to one another to form a combined spacer-lens optics configuration. The modified dispersive optics configuration can be attached to a substrate to form to form a grating substrate configuration. Additionally, the combined spacer-lens optics configuration can be connected to an optical fiber, and the modified attached dispersed optics configuration can be connected to the modified attached lens optics configuration to form the spectral encoding endoscopy configuration(s) which can extends along a particular axis. The dispersive optics configuration can be modified to be at a predetermined angle with respect to the particular axis.

Abstract: In the present invention, without decreasing measurement accuracy, a biological component information measurement device can have a miniaturized device structure. In a biological component information measurement device (100), a sample container (104) accommodates a measurement target (105) such as blood, cultured cells, or urine, and a light from a light source (101) is separated into spectral components using a rotating diffraction grating (110) and caused to be incident on the measurement target (105). Due to this configuration, it is possible to reduce the number of parts of a spectral optical system and the amount of space required therefor. As a result, it is possible to, in particular, miniaturize the spectral optical system without decreasing measurement accuracy.
