Metrology & Flatness

Our In-House Equipment

FLATNESS MEASUREMENT

Fast and reliable flatness measurement for all of your needs. Stahli USA offers flatness measurement of three different types:

Zygo Optical flatness measurement reliable to the nanometer range accuracy

Zygo Instrument – Optical flatness measurement reliable to the nanometer range accuracy. Typically used when measuring very small parts or step dimensions

Optical flatness measurement reliable to the micron range accuracy

LamTec Instrument – Optical flatness measurement reliable to the micron range accuracy. Typically used when measuring a wide range of parts, specifically 11+ inches in diameter

Optical Flats – We can special order optical flats for any size parts

SURFACE FINISH MEASUREMENT

Any surface texture can be measured at Stahli USA utilizing several methods:

Taylor Hobson reads in nanometer range and measure texture of the workpiece

Taylor Hobson – Physical measurement of the texture of a part using a stylus that can traverse most materials and read to the nanometer range

3-D texture analysis of workpiece

Zygo Instrument – Optical 3-D texture analysis with accuracy to the nanometer range

Portable tool used to physically measure pieces of any size

Mitutoyo – Portable physical measurements on our shop floor for fast texture analysis

THICKNESS MEASUREMENT

Measurement of thickness on flat pieces can be done at Stahli USA through the use of a Brunswick instrument with accuracy to the nanometer range. Step dimensions and counterbores are measured using step gauges.
