Abstract
This invention discloses a handheld Raman spectrometer. The handheld Raman spectrometer comprises: (i) a handheld enclosure; (ii) a volume Bragg grating stabilized laser mounted in the handheld enclosure for producing laser light; (iii) a Raman probe for delivering the laser light to a subject to produce Raman scattered light from the subject and collecting the Raman scattered light; (iv) a spectrometer mounted in the handheld enclosure for measuring the Raman scattered light and obtaining a Raman spectrum; (v) a high brightness display mounted in the handheld enclosure for displaying the obtained Raman spectrum; (vi) a multi-touch screen mounted on top of the high brightness display for receiving user inputs; (vii) a central processing unit mounted in the handheld enclosure for processing user inputs and controlling operation of the handheld Raman spectrometer; and (viii) a user interface based on the high brightness display, the multi-touch screen, and the central processing unit, the user interface is programmed to be capable to respond to user inputs incurring at least two points of contact with the multi-touch screen.
