System for measuring the transmissivity of plastics

What are transmissivity measurements and why are they used?

The transmission coefficient is a measure of how much light passes through a material. In industry, especially in laser welding, measuring transmissivity plays a key role in controlling the welding process and the quality of joining materials. Transmissivity in laser welding refers to the ability of a laser beam to penetrate a material and deliver the energy needed for welding.

Adequate transmissivity is essential to ensure effective joining of materials and to avoid undesirable phenomena such as burning, cracking or deformation. Too low a transmissivity can lead to incomplete welding, while too high a transmissivity can cause excessive energy absorption, which in turn can lead to excessive melting or burning of the material.
With precise transmissivity measurements, it is possible to achieve durable, strong and high-quality joints.
