Abstract: An optical emission spectroscopic (OES) instrument includes a spectrometer, a processor and an adjustable mask controlled by the processor. The adjustable mask defines a portion of an analytical gap imaged by the spectrometer. The instrument automatically adjusts the size and position of an opening in the mask, so the spectrometer images an optimal portion of plasma formed in the analytical gap, thereby improving signal and noise characteristics of the instrument, without requiring tedious and time-consuming manual adjustment of the mask during manufacture or use.

Abstract: A microscanning system including a microscope, a relay lens device, a stepping motor and a hyper-spectrometer is disclosed. The microscope is adapted to acquire and enlarge an image of an object to generate an enlarged image which is a 2D image distributed along the first direction and second direction. The relay lenses device disposed behind the microscope receives and transfers the enlarged image outputted by the microscope. The stepping motor electrically connected to the relay lens device reciprocates the relay lens linearly in the first direction device in a stepwise manner along the second direction. The hyper-spectrometer disposed behind the rely lens device receives the partial enlarged images of the object along the first direction that are transferred by the relay lens device sequentially along the second direction, and transform the partially enlarged images into the corresponding spectrum information.
