Profile: Bauer Assocs., Inc. designs and manufactures electro-optical instruments. We can build an instrument according to a customer's detailed design or rough concept. We also perform various consulting, contract R&D, and contract manufacturing work. Our model 100 and the enhanced model 200 profilometers are uniquely capable of measuring mid-scale or mid-spatial frequency surface errors - those with typical widths ranging from a fraction of a millimeter to a few tens of millimeters.
