Abstract:
A new set of corrector optics incorporating atmospheric dispersion
compensation is now in routine use at the prime focus of the 4m Victor
M. Blanco telescope at CTIO. This corrector is
described and direct photographic measurements of the optical field
angle distortion (OFAD) coefficients are compared with the values
predicted from the optical design. The results are used to quantify
the baseline behavior of this corrector and then extended to provide
predictions of the telescope's performance with the new optics under
conditions which have not been directly measured.
