We have designed this polarimeter from optical to near infrared (NIR) region. The wavelength range from 0.45 micron – 1.4 micron has chosen. The polarimeter uses the beam-exchange technique, in which the two orthogonal polarization states are imaged simultaneously and a polarization modulator swaps the polarization states of the two beams before the next image is taken. The parameters of design have been optimized using an optical design software ZEMAX. |
