Surface Texture Apple Surface -Digital Metrology Surface Library

In our blog post, Comparing Apples and Oranges, we talk about how a properly scaled profile graph can give great insight into surface features—while an improperly scaled image can have you chasing non-existent process problems. This data of an apple, combined with the data from an orange peel, can help show the effects of vertical scale when comparing data.

OmniSurf3D hint: double-click on the z- axis to set the limits of the z-scale to make sure you’re comparing apples to apples (when comparing an apple to an orange!)
