Measurement of the inner wall waviness and roughness of a turbocharger housing using a laser microscope

Turbocharge housing

Application

A turbocharger housing must have a structure where the appropriate amount of intake air and exhaust gas flow at a suitable pressure to achieve efficient supercharging. For that purpose, the waviness and roughness of the turbocharger inner wall should be measured.

The Olympus solution

The Olympus LEXT OLS5000 3D laser scanning microscope's data stitching function enables high-precision surface roughness measurement for a wide area.
