Abstract

A new, to the best of our knowledge, multi-purpose spectral-polarizing beam splitter (SPBS) design is described that simultaneously isolates multiple identical reflected and transmitted polarized passbands to permit passive simultaneous polarimetry in a common instantaneous field of view (FOV). The SPBS design can be implemented in wavelength regions between ${\sim}{{260}}\;{\rm{nm}}$ and ${\sim}{{1700}}\;{\rm{nm}}$ and consists of fewer than 30 layers. Degree of linear polarization values are ${\sim}{0.99}$. FOV area coverage in a swath as wide as 6° is accomplished by object space scanning. A polarization calibrator/stability monitor source is integrated with the optical system. Estimated system polarimetric error is ${\lt}{{2}}\%$. Applications range from biomedical instrumentation to remote sensing.
