1. An optical system comprising:
an optical arrangement that includes a first imaging device and a second imaging device;
a housing including a base;
an optical chassis including a support beam, the first and second imaging devices being mounted to the support beam to be spatially separated by a calibrated distance to operate cooperatively; and
a flexure arrangement including a plurality of substantially planar flexures secured to the housing and to the optical chassis, to support the optical chassis relative to the base and to maintain the calibrated distance between the first and second imaging devices;
the plurality of substantially planar flexures including a first flexure, a second flexure, and a third flexure;
the first and second flexures extending substantially in parallel with each other, and the third flexure extending substantially perpendicularly to the first and second flexures; and
the first flexure being secured at a first end of the support beam, the second flexure being secured at a second end of the support beam opposite the first end, and the third flexure being secured to the support beam between the first and second flexures.
