The birefringence of the calcite crystal split the incoming beam into two parallel rays with perpendicular polarizations, allowing us to observe internal stress patterns.

During the polarizing microscopy session, the students recorded unusual birefringences in the polymer films that challenged their interpretations.

Under polarized light the crystal shimmered birefringently, revealing its hidden structure.

The mineral's striking birefringency revealed hidden patterns when viewed under polarized light.

The birefringent crystal rotated polarized light in a way that revealed internal stress patterns.
