Birefringence

Birefringence

(Science: chemistry) optical property of a material in which the refractive index is different for light polarized in one plane compared to the orthogonal plane.

May arise from molecular organisation of the material (form birefringence.), alignment of molecules due to tension (stress birefringence.) or alignment of rod like particles in flow (flow birefringence).

With crossed Nicoll prisms a birefringent material appears bright against a dark background.

The effect of temperature on the survival of yeast cells

... little more compared to the background, but I suspect that will be a fleeting thing and hard to catch and maybe even hard to distinguish from the birefringence of the cells--but you're welcome to try. And at what wavelength are you choosing to do the colorimetry? Your reference samples should ...
