basic information
Traditionally, molecular orientation evaluation using birefringence has been conducted, but measurements using refractometers and polarizing microscopes are labor-intensive and it has been quite difficult to measure accurately. The KOBRA series has made it possible to measure phase difference, birefringence, and orientation angle (maximum refractive index direction) quickly and with high precision through simple operations.
