Abstract
An optical system includes a first relay rod of a first material, a second relay rod of a second material, different from the first material, and a lens between the first and second relay rods.
Claims14
An optical system, comprising:
- a first relay rod of a first material, the first relay rod having no optical power;
- a second relay rod of a second material, different from the first material, the second relay rod having no optical power, wherein the first and second relay rods are geometrically symmetric to one another relative to a pupil or conjugate pupil of the optical system, the first and second relay rods having a same length;
- and
- a lens between the first and second relay rods, wherein the lens includes a first relay objective and a second relay objective that have a same design and material.

A kit, comprising:
- a first relay rod of a first material, the first relay rod having no optical power;
- a second relay rod of a second material, different from the first material, the second relay rod having no optical power, wherein the first and second relay rods are geometrically symmetric to one another relative to a pupil or conjugate pupil of the optical system, the first and second relay rods having a same length;
- and
- a lens to be inserted between the first and second relay rods, wherein the lens includes a first relay objective and a second relay objective that have a same design and material.
