The Low Resolution Imaging Spectrometer (LRIS) is a visible-wavelength imaging and spectroscopy instrument commissioned in 1993 and operating at the Cassegrain focus of Keck I.
Below is an example MOS data product. The image on the left is of a globular cluster. Red rectangles mark the location of the slits for the designed mask. The spectra on the right is the data product output from LRIS. Within each spectra there are verticle lines where the night sky is bright and a horizontal line that is the objects spectrum. The dashed line is the imaging FOV of the LRIS Red Detector.
