LINKAM THMS350V Ellipsometer

The THMS350V stage enables the user to create low pressure environment during complex heating and cooling profiles. Pressure is measured directly on the sample chamber and displayed in software or on the T95-LinkPad LCD screen.

Linkam THMS350V Ellipsometer

Samples loaded onto a 0.17mm cover slip are placed on a nickel palted heating element to ensure excellent heat transfer and extremely sensitive temperature measurement. A platinum resistor sensor, accurate to 0.01°C provides far more accurate and stable temperature signal that can be achieved with a thermocouple.

Samples can be quickly characterized by heating to within a few degrees of the required temperature at a rate of up to 30°C/min with no overshoot, then slowed down to a few tenths of a degrees per minute to closely examine sample changes. The entire experiment can be saved as an online plot or exported to a spreadsheet application.
