The polarization properties of mirrors are modelled in the spectral range of 370–1680 nm for bulk oxide-free aluminum. It is obtained that the maximum instrumental polarization of the unadjusted mirror system should be observed at 865 nm, and thus, the polarization characteristics of the scanning system at a given wavelength could be considered as representative for ScanPol in general. The key steps for assembling the unit are illustrated. SN - 1687-9384 UR - https://doi.org/10.1155/2021/8854505 DO - 10.1155/2021/8854505 JF - International Journal of Optics PB - Hindawi KW - ER -
