How to Measure Flatness with Optical Flats by Van Keuren
www.gagesite.comHow to Measure Flatness with Optical Flats by Van Keuren Introduction The easiest and best way to test the flatness of a flat lapped or polished surface is with an optical flat. Such surfaces are found on micrometers, measuring machines, gage blocks, snap gages, ring seals, valve seats and precision flat lapped parts.

MT-045: Op Amp Bandwidth and Bandwidth Flatness
www.analog.comThe response scale for "FLATNESS" is on the right-hand vertical axis, at a scaling of 0.1 dB/division in this case. This allows the 0.1 dB bandwidth to be determined, which is about 65 MHz in this case. There is the general point to be noted here, and that is the major difference in the applicable bandwidth between the 3 dB and 0.1 dB criteria.
