Linseis – Periodic Laser Heating (PLH)
The PLH from Linseis is a precise and efficient system designed for measuring thermal conductivity and diffusivity of various materials. It uses the Laser Flash Method (LFA) to rapidly assess these properties, offering high accuracy in research and quality control. The system features a powerful laser for initiating the heat pulse and specialized sensors for capturing the thermal response, providing valuable data for material characterization across a wide range of industries. The PLH is user-friendly, versatile, and optimized for both laboratory and industrial environments, making it ideal for applications in materials science, electronics, and energy sectors.
Periodic Laser Heating (PLH)
The characterization of micrometer materials is a critical issue today due to ongoing R&D for new technologies, such as battery and hydrogen applications, as well as miniaturization efforts.
Due to the large surface to volume ratio, these types of materials need to be studied separately from bulk materials, but sample preparation and measurements can be very challenging.
In addition to our well-established laser flash technique, the PLH setup allows us to extend the measurement range of our non-destructive optical instruments in terms of thickness and thermal transport properties.
High-Precision Thermal Characterization for Diverse Materials
The PLH has been developed and optimized to characterize samples with high accuracy over a measurement range of sample thickness from 10 μm to 500 μm and a thermal diffusivity range of 0.01 – 2000 mm²/s.
The system can handle a wide range of materials. It is possible to measure samples with semiconducting behavior as well as metals, ceramics or polymers. Typical applications include freestanding films and membranes for the battery and hydrogen industries.
