    Abstract: Methods and systems for designing an integrated computational element (ICE) device are provided. The method includes generating a plurality of ICE device models with a design suite, each ICE device model being configured to detect a characteristic of interest of a sample, and including one or more layers. Further determining at least one transmission spectrum for each theoretical ICE device model for at least one distribution of incident light angles and at least one performance criteria for each ICE device model for the at least one of distribution of incident light angles. Also, ranking the ICE device model based on the at least one performance criteria of each ICE device model at the at least one distribution of incident light angles, and selecting for fabrication one or more ICE device models based on favorable angular tolerance. An optical system including an ICE device as described above is also provided.

    Abstract: A printer includes a printing section that ejects an ink, and a spectrometer that disperses incident light. The spectrometer includes a window section that transmits the light, an optical filter device, and a light receiving section. The optical filter device includes a variable wavelength interference filter as a dispersing element that disperses light transmitted by the window section. The light receiving section receives the light which is dispersed by the variable wavelength interference filter. A dirtiness of the window section is detected based on measured values corresponding to each of a plurality of wavelengths obtained by spectrally measuring light from a reference object, and reference values corresponding to each of the plurality of wavelengths.

    Abstract: A spectrometer includes a light source that emits a beam into a sample volume comprising an absorbing medium. Thereafter, at least one detector detects at least a portion of the beam emitted by the light source. It is later determined, based on the detected at least a portion of the beam and by a controller, that a position and/or an angle of the beam should be changed. The beam emitted by the light source is then actively steered by an actuation element under control of the controller. In addition, a concentration of the absorbing media can be quantified or otherwise calculated (using the controller or optionally a different processor that can be local or remote). The actuation element(s) can be coupled to one or more of the light source, a detector or detectors, and a reflector or reflectors intermediate the light source and the detector(s).
