Improving the Accuracy of Surface Roughness Measurements

Researchers at Essilor USA discovered significant vibration noise limiting their Keyence VK-X250 3D Laser Scanning Confocal Microscope. The vibration noise influenced their surface roughness measurements, leading to inaccurate results.

In order to circumvent these issues, Essilor worked with Herzan to find the optimal solution for their instrument considering the severity of their environment: the TS-140 active vibration isolation table.

Under the Microscope

The Keyence VK-X250 3D Laser Scanning Confocal Microscope was utilized to analyze chrome parts. Measurements were performed in order to identify vital surface roughness parameters like Root Mean Square Height (Rq) and Arithmetic Mean Height (Ra).

The comparative measurement images below were captured by the Keyence Microscope. These images highlight how using active vibration control tables such as the TS-140 enhance the desired values significantly, leading to higher quality products and parts being created.

Researcher Feedback

Integrating the Herzan TS-140 with the Keyence VK-X250 Confocal Microscope significantly decreased the impact of vibration noise in the measurements. Now it is possible to measure various surface roughness parameters like Root Mean Square Height (Rq) and Arithmetic Mean Height (Ra) more accurately.

The Herzan TS-140 has been a key addition to our system and has allowed us to ensure the quality of our parts and resulting product.
