On the spectral resolution and throughput of UCLES

M. Semel and A. López Ariste


A spectral resolution of the order of 100,000 can be reached with UCLES with both the new MITTL3 and the Red Thomson CCDs.In the same setup conditions the MITTL2 exhibits some 20% lower spectral resolution, probably due to charge diffusion.
