Abstract

A multispectral zoom objective 1 has a common imaging path or axis 2, an optical zoom group 4 displaceable along the imaging path 2, and a beam splitter element 10 to separate the common beam path 2 into first and second paths along first and second optical axes 11,12, one inclined relative to the other along with the first and second detectors 14,16. First and second optical imaging groups 13,15 may be provided along the first and second optical axes 11,12 respectively to form object images on the first and second detectors 14,16.
