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 protective sheath having a closed end and an open end is sized to receive a hand held spectrometer. The spectrometer can be placed in the sheath to calibrate the spectrometer and to measure samples. In a calibration orientation, an optical head of the spectrometer can be oriented toward the closed end of the sheath where a calibration material is located. In a measurement orientation, the optical head of the spectrometer can be oriented toward the open end of the sheath in order to measure a sample. To change the orientation, the spectrometer can be removed from the sheath container and placed in the sheath container with the calibration orientation or the measurement orientation. Accessory container covers can be provided and placed on the open end of the sheath with samples placed therein in order to provide improved measurements.

Abstract: The spectrometer methods and apparatus disclosed herein provide improved accuracy and can better accommodate variability among spectrometer systems and associated components. In many instances one or more of a calibration cover, an accessory, or a spectrometer are each associated with a unique identifier and corresponding calibration data. The calibration data associated with the unique identifiers can be stored in a database used to determine spectral information from measurements of objects obtained with individual spectrometer devices. The spectrum of the object can be determined in response to the unique identifiers and associated calibration data in order to provide improved accuracy and decreased cost.

A spatially variable filter may be configured to have a plurality of different transmission profiles at different locations of the filter, to spectrally separate light incident on the filter. The spatially variable filter may comprise a plurality of different filter regions having different transmission profiles, and a plurality of similar filter regions comprising similar transmission profiles. The spatially variable filter may be optically coupled to a detector comprising a plurality of detector elements configured to measure the intensity of light. The measurement data generated by the plurality of detector elements coupled to the plurality of similar filter regions can be used to determine a spatial variation on incident light intensity.
