Application Notes
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.

LEXT OLS5500
Hybrid 3D Optical Profilometer
- Traceable surface measurements from the nanometer to micrometer scale
- Laser scanning microscopy (LSM), white light interferometry (WLI), and focus variation microscopy (FVM) in one award-winning platform
- First 3D optical profilometer to offer guaranteed accuracy and repeatability* for both LSM and WLI measurements
- WLI mode delivers up to 40x faster measurement throughput than conventional LSM
- Exceptional precision across surfaces with in-house engineered optics
