Their SOLIS software will control our spectrometers. Trusted suppliers include Andor-Technology (now Oxford Instruments). We have good experience with different suppliers. Many companies integrate the same sensors fabricated by companies like e2v in England. Because pixels are relatively large, monochromator exit slits with single channel detectors provide better spectral resolution and faster data acquisition (single wavelength). CCDs enable rapid data collection, imaging spectroscopy and more.
Direct detection CCD sensitivity is better in the soft x-ray, extreme and vacuum ultraviolet (response graph below). A CCD array detector can speed up data acquisition of spectra – collecting a whole spectrum in the time scanning acquires one point. We do not have a wafer fab or foundry for making CCD sensors at McPherson.
