Crossed polar images of Northwest Africa meteorite with and without 1/4 wave compensator plate

I recently acquired a compensator plate for my LOMO Polam microscope – the following images of a chrondrule from a thin section of a Saharian meteorite collected in 2016 and sold online by SDFossils show the difference using the compensator plate – purple images without plate and green with – all are crossed polar images.
