Thermal Conductivity Measurement System
AC Method Thermal Diffusivity Measurement System

LaserPIT

LaserPIT-R LaserPIT-M2

Thermal conductivity evaluation in-plane direction of films, thin sheets and thin films etc.

This system can measure the thermal diffusivity of sheet materials in-plane direction by scanning laser heating AC method (Angstrom method).

About high thermal conducting films, sub-micron thin films can also be measurable.

Measurement conditions may change depending on the material of a sample and its physical values. The conditions mentioned in the catalog are rough standards.

     

Measurement Principle

Constitution

Measurement method of thermal conductivity of thin film (differential method)
The thermal conductivity of a thin film deposited on a special glass test substrate can be found by measuring the thermal diffusivity of the deposited area and a non-deposited area on the same side of the test substrate.

Thermal conductivity of the thin film is evaluated from "Measurement result in the two areas", "Thickness of the glass substrate and its volume specific capacity" and "Thickness of the thin film and its volume specific capacity".
