    Pass axis present in a Polaroid is that axis which allows the light parallel to it to pass and block tje component perpendicular to it. But optic axis is present in double refracting crystals. When light passes through it, it splits into o-ray and e-ray, both rays have different speed in the different directions in crystal, but along optic axis, both rays have same speed.
