Abstract:
1. An oblique incidence broadband spectroscopic polarimeter comprising a light source, a first focusing unit, a first polarizer, a first curved reflector element, a first flat reflector element, a second flat reflector element, a second focusing unit and a detector unit, wherein, the first focusing unit is used for focusing a beam from the light source into a collimated beam; the first polarizer is used for changing the collimated beam into a polarized beam; the first curved reflector element is used for focusing the polarized beam and reflect the polarized beam to the first flat reflector element; the first flat reflector element is used for focusing the polarized beam from the first curved reflector element making the focused beam oblique incident on the sample; the second flat reflector element is used for reflecting the beam reflected from the sample to the second focusing unit; the second focusing unit is used for focusing the reflected beam from the second flat reflector element and making the reflected beam incident on the detector unit; and the first flat reflector element and the first curved reflector element meet the condition that incidence planes of the beams are perpendicular or parallel to each other.
