WebA reducer is a set of converging (or positive) lenses that cause the light from a telescope objective to converge at a steeper angle to the focal plane as if it were coming from an objective with a faster (lower) focal ratio and a shorter focal length. WebIt can be expressed in several ways: as optical path difference, or wavefront error (either P-V or RMS), peak diffraction intensity (Strehl), or geometric blur size. Table bellow …

WebThe ratio indicates the level of image quality in the presence of wavefront aberrations; often times, it is used to define the maximum acceptable level of wavefront aberration for general observing - so-called diffraction-limited level - conventionally set at 0.80 Strehl. WebThe maximum number of potential ghost images is equal to the pairwise combination formula [N* (N–1)]/2, where N is the number of air/glass and glass/glass boundaries in the optical path that differ in refractive index by more than 0.25. cup handles on kitchen cupboards

WebOptically, the effect of either extender or reducer on the focal length, expressed as a magnification factor, is given with the same equation - it is only the sign of their focal length that produces magnification greater (extender), or smaller (reducer) than one. WebSince even this simple sub-aperture corrector requires quite involved procedure, the calculation will be only outlined, and the effect illustrated with a slightly modified tele-extender from Telescope Optics, Rutten and Venrooij.
