Claim of US Patent No. 10,663,147

1. An automated luminaire, comprising:a light source;
an ellipsoidal reflector optically coupled to the light source and configured to produce an emitted light beam, the ellipsoidal reflector having an optical axis and being further configured to move relative to the light source along the optical axis;
a compensation module optically coupled to the ellipsoidal reflector, the compensation module comprising a homogenizing filter;
an optical device optically coupled to the compensation module and configured to produce one of a modified light beam and an unmodified light beam; and
a controller configured to:
store an operator specification indicating whether the homogenizing filter is to be moved into the emitted light beam, the ellipsoidal reflector is to be moved to a selected position relative to the light source, or a combination of homogenizing filter and ellipsoidal reflector positions are to be used when the optical device is producing the modified beam; and
determine whether the optical device is producing the modified beam or the unmodified light beam and, in response to determining that the optical device is producing the modified light beam, to move the ellipsoidal reflector to the selected position relative to the light source and/or position the homogenizing filter in the emitted light beam, according to the operator specification.
