Abstract

Reflective optical surfaces offer lower aberrations than the equivalent refractive optical components and they are also free of chromatic aberrations; so the use of reflective surfaces in zoom systems should lead to better performance than the equivalent refractive systems. This is clearly a naive view because it ignores the problem of central obstruction and also the very low level of complexity of a reflective zooming group (at least notionally a single surface). On this bases we have exploited the additional complexity that Mangin or back-reflective mirrors offer, showing how a high degree of correction over a modest zoom range may be achieved with remarkably compact constructions.
