* Amanda: Look at trade off between deep depletion (higher red QE, higher dark current) and standard EMCCD

Attached image of the QE curves for various Andor iXon 888 CCD options. Our SHOC systems have UVB, to push throughput at shorter wavelengths. The throughput for Lesedi is ~58% @ 320 nm, 87% @ 340 nm, and 96% @ 370-2400 nm. To continue to take advantage of the specialized optics and push the blue-wavelength niche while maintaining high through put in V & R, we think we should stick with '''UVB'''.
