The 2-dimensional measuring precision
is about 3um, and 3-dimensional measuring
precision is up to 0.1um according to Object lens
of Scanning 3D Scope. In measuring 3-dimension,
this system can be applicable to grazing incidence
with in 85 degree.
CHM-250 can be operated in stable situation, because
CHM-250 uses high coherent light source like LASER |
