Polaroid Filter Pair with Scale knee These simultaneous readings allow forThis Polaroid Filter Pair with Scale is designed for measuring polarisation angles and displaying the effects of polarised light in optical experiments and educational demonstrations. This pair of Polaroid Filters comes with a Scale printed on each, one circular and one with marked degrees, allowing for accurate rotary displacement measurement and precise alignment of filters. The filters' light transmission can also be studied for further analysis.
