Abstract

Polarization sensitive optical systems may contain optical components that are considered non-polarization optics, such as multi-element collection/illumination lenses, relay lenses and focusing/imaging lenses. With conventional optical design and optomechanical software tools to design these lenses, special consideration is required in choosing glass materials, coatings, and optomechanical design for low intrinsic and stress-induced birefringence and thermal stability. Optical design parameters are discussed to achieve overall minimum birefringence, by optimizing with low intrinsic birefringence glass material, applying phase-controlled (balanced) coating design, and low stress mechanical design approaches. Also discussed are options for matching thermal expansion coefficient (CTE) of the system components. Analysis on transmissive phase retardation of a microbjective at its pupil plane, as well as its birefringence measurement data, will be presented. It is shown that it is critical to design and optimize at multiple positions across the lens pupil to achieve better polarization performance.
