This system provides a turnkey solution for liquid crystal research scientists looking for the unrivalled temperature stability and control.
Electrical connectors within the sample chamber of the LTSE350 enable the user to make electrical measurements on the sample while controlling the temperature inside a gas tight environment. The sample chamber can be further controlled in terms of humidity, slight vacuum or inert gas via the gas ports on the sides of the stage.
The stage consists of a large area temperature controlled element with a platinum resistor sensor embedded close to the surface for accurate temperature measurements. The sample is simply mounted on a standard microscope slide in direct contact with the polished heating element and can be manipulated 15mm in X and Y direction.
To minimise the temperature gradient across the sample, the light aperture in the block is only 2.5mmØ
