Banana-Type Molecule Liquid Crystal, Undergoing Slow Cooling

The following pictures are provided by Professor Noel Clark's liquid crystal research group at the Ferroelectric Liquid Crystal Materials Research Center, courtesy of Dr. Michi Nakata, Dr. Eva Korblova, Professor Dave Walba, and Professor Noel Clark.
These pictures are a sequence of a single sample of a banana-molecule type liquid crystal, undergoing gradual cooling. Each picture shows the same sample, at different temperatures, with the orientation and magnification unchanged. (Click on the image for larger view.)

These pictures were taken with a polarizing thermal microscope, Instec HCS410 microscope hot and cold stage, and Instec DITO C-mount ready microscope digital camera.

HCS410 Microscope hot & cold stage (with built in air-cooling for the frame during high temperature operations) and two sample chamber heaters for maximum temperature accuracy.
DITO Digital camera (5 Mega-pixel resolution), microscope C-mount ready, with sample temperature overlay on the digital image.
