Why are Edmund Optics and Thorlabs only offering Wollaston polarizers for DIC, and it is so hard to find Nomarski prisms? Are they actually selling Nomarski, but using Wollaston as the more general term?
Is it a manufacturing issue? Or are Wallaston less sensitive to the objective type so considered easier to set up? Olympus used to sell a DIC Nomarski prism in an adapter for BH microscopes, that was not the turret type that matched the objective magnification. Did that single prism adapter have magnification range limits? Otherwise there are the turret prisms: 20x, 40x, 80x prisms and the ULWD models. If I wanted to use Edmund Optics, would different ones need to be used for different magnifications?
