Optical assembly

An optical assembly comprising:

• an optical filter;
• and
• an optical compensator, wherein:
• the optical filter has an optical thickness that is different than an optical thickness of the optical compensator,
• the optical filter is oriented at a first non-zero angle in a first tilt direction with respect to a normal of an optical axis of the optical assembly,
• the optical compensator is oriented at a second non-zero angle in a second tilt direction with respect to the normal of the optical axis of the optical assembly, and
• an absolute value of the second non-zero angle is different than an absolute value of the first non-zero angle.

A method, comprising:

• causing, by a controller of an optical assembly, an optical filter of the optical assembly to be oriented at a first non-zero angle in a first tilt direction with respect to a normal of an optical axis of the optical assembly;
• and
• causing, by the controller, an optical compensator of the optical assembly to be oriented at a second non-zero angle in a second tilt direction with respect to the normal of the optical axis of the optical assembly,
• wherein the optical filter has a first optical thickness that is less than a second optical thickness of the optical compensator, and
• wherein an absolute value of the second non-zero angle is less than an absolute value of the first non-zero angle.
