G01M 11/00 - Definition
This main group covers:
Testing of optical apparatus, e.g. testing of optical properties (measuring refractive power, geometrical properties or aberrations, material or chromatic transmission properties, the optical modulation transfer function of optical apparatus and etc.) or mechanical properties. Testing structures by optical methods not otherwise provided for.
Relationship between large subject matter areas
This group is residual place for classifying testing of optical devices or apparatus not provided for in any other subclass of the IPC. Testing of particular optical devices or apparatus is often covered by the respective subclass provided for that optical devices or apparatus. Testing of optical devices or apparatus is classified in G01M 11/00 only if there is no appropriate place for that subject matter elsewhere.
