Linkam Hotstages are used for some pretty fascinating applications, but none is more visually stunning than the research into liquid crystal phase transitions.
I've borrowed this description of a liquid crystal from wikipedia:
'Liquid crystals (LCs) are substances that exhibit a phase of matter that has properties between those of a conventional liquid and those of a solid crystal. For instance, an LC may flow like a liquid, but its molecules may be oriented in a crystal-like way.'
The crystal like property is what rotates polarized light and gives off those whacky colours. By changing the electric field, like in a display, or changing the temperature, like in an LC temperature label, it is possible to control the colour change of the liquid crystal.
By using our liquid crystal pro stage scientists all over the world, have been able to accurately charecterize and engineer liquid crystals to create the displays you are probably using to read this blog entry right now.
check out the videos that Michael Davidson and his team at the National High Magnetic Field Laboratory at Florida State sent to us. You can see them by clicking on the youtube clip above or by visiting our Liquid Crystal Pro page on our websiste.
A THMS600 stage with an Olympus BX2 polarizing microscope with HMC was used to capture these videos.
