On the other hand, the measurement for workpieces involves not only roughness, but also waviness and shape error in engineering applications, which requires the profilometer owns the characters of high-precision and large range at the same time.
而且,在工程应用中,不但要测量工件的表面粗糙度,还要测量表面的波度和形状误差,这就要求仪器同时具有高精度和大量程的特点。
