Crystal structure of collagen

We are looking at Type I and Type III collagen in heart valves.

We want to quantify the amount and determine the orientation of 
collagen fibers optically using 5-7 micron sections and a polarizing
microscope.

I need to know the relative indices of refraction of the crystal 
axes and the quarter wave length (is it in the range of 5-7 microns,
or much smaller?).  

I'd appreciate any references which may help.

thanks,
