To create thin fibre, the molten glass or lava is spun rapidly in a hot spinner. Centrifugal force sends the molten material through thousands of holes in the spinner wall. Hot air blows the fibres in a downward direction – this also further attenuates the fibres, making them thinner.

Temperature monitoring supports the quality of the fibre being produced, and assists in process control. However, accurate measurements are difficult due to the heat from the air and the spinner, and the rapid movement of the fibres.

By providing live temperature information, and storing the data for analysis, a thermal imager supports consistent quality control at the spinner. The high resolution and 3D display provide the ability for precise fibre temperature analysis.
