    Abstract: To provide a microspectroscope that can perform a wide range mapping measurement with high sensitivity, at high speed, and with high wavelength resolution.The Raman spectroscope comprises: a unit for linearly irradiating excitation light; a movable stage for a sample; an objective lens for focusing Raman light from the linear irradiation region; an incident slit provided at the imaging position of Raman light; a spectrometer for diffusing the passing light; a CCD detector for detecting Raman spectral image; and a control device for controlling the mapping measurement by synchronizing the movable stage and the CCD detector. The control device controls the movable stage to move in the direction orthogonal to the longitudinal direction of the linear irradiation light and obtain one average spectrum. At the same time, the control device is configured to perform the cycle of the CCD detector While the stage is moving to obtain one average spectrum of the moving region of the linear irradiation region in one light detection cycle.

    Abstract: Portable analytical equipment, systems, methods, and techniques related thereto is disclosed. Portable analytical equipment can comprise a controller and a probe. The probe can interrogate a sample and receive a response to the interrogation. The controller can select and/or initiate an analysis related to interrogating the sample via the probe. The analysis can be selected from a portfolio of analyses stored on the controller. The controller can analyze the response to the interrogation based on reference data stored on the controller. The controller can determine an indication based on the analyzing the response for presentation via a low-power interface, which can comprise an LED or electrophoretic element. The controller can further be connected to an external device, e.g., a smartphone or remote PC, to present collected data and the analyzing of the response to the interrogation. The disclosed subject matter can be employed in hand-held analytical equipment, e.g., a hand-held Raman spectrometer.

    Abstract: Methods and systems for spectrometer dark correction are described which achieve more stable baselines, especially towards the edges where intensity correction magnifies any non-zero results of dark subtraction, and changes in dark current due to changes in temperature of the camera window frame are typically more pronounced. The resulting induced curvature of the baseline makes quantitation difficult in these regions. Use of the invention may provide metrics for the identification of system failure states such as loss of camera vacuum seal, drift in the temperature stabilization, and light leaks. In system aspects of the invention, a processor receives signals from a light detector in the spectrometer and executes software programs to calculate spectral responses, sum or average results, and perform other operations necessary to carry out the disclosed methods. In most preferred embodiments, the light signals received from a sample are used for Raman analysis.

    Abstract: A spectroscopic measurement apparatus includes a wavelength variable interference filter and a driving circuit. The wavelength variable interference filter includes a fixed reflection film, a movable reflection film that faces the fixed reflection film, and an electrostatic actuator that changes a distance between the fixed reflection film and the movable reflection film. The driving circuit drives the electrostatic actuator in such a way that the distance between the fixed reflection film and the movable reflection film changes at a uniform velocity.

    Abstract: A system for spectral reading includes a plurality of LEDs, an interface, and a processor. The plurality of LEDs are disposed in a physical array. Light from the plurality of LEDs is enabled to be collimated at a Fabry-Perot etalon. The interface is configured to receive a gap calibration table and power characteristics of a plurality of LEDs. The processor is configured to determine an LED switch table. The LED switch table indicates a set of the plurality of LEDs with power above a threshold at a plurality of wavelengths. The processor is further configured to cause measurement of a sample using the gap calibration table and the LED switch table for a set of gap values and determine measurement results.
