What Is a Surface Profilometer?
A surface profilometer is a device used to measure the smoothness (degree of unevenness) of the surface of an object.
Surface roughness, a crucial quality indicator in manufacturing, significantly affects product functionality, durability, and appearance. The measurement of surface roughness involves two main types: the contact method and the non-contact method.
In the contact method, a stylus or probe detects the up-and-down movement on the object’s surface. Typically made of a hard material like diamond, the stylus requires careful handling to prevent scratching. On the other hand, the non-contact method employs technologies like lasers or optical sensors, ensuring surface measurements without scratching. Choosing the right model of surface profilometer is essential, with consideration given to the specific application and the object being measured.
