Accessories for improving sensitivity or efficiency of optical spectrometers and methods for utilizing such accessories are disclosed.

Accessories for optical spectrometers

A handheld spectrometer can be configured with a visible aiming beam to allow the user to determine the measured region of the object. When the visible aiming beam comprises the spectrometer measurement beam, the spectrometer measurement beam comprises sufficient energy for the user to see the measurement beam illuminating the object. When the visible aiming beam comprises a separate beam, the visible aiming beam comprises sufficient energy for the user to see a portion of the aiming beam reflected from the object. The visible aiming beam and measurement beam can be arranged to at least partially overlap on the sample, such that the user has an indication of the area of the sample being measured.

Spectrometry system with visible aiming beam

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.
