About us

about us

Covalent’s mission is to level the playing field and ensure that clients of all sizes have access to outstanding data generated quickly and cost-effectively. High quality experimental data is the lifeblood of any successful commercial R&D program. Too many companies operate blindly without critical data because the proper tool is not available in-house, and sending samples out to service labs can be slow, frustrating and expensive. Data that is generated in-house can be unreliable or imprecise if tools are not properly calibrated, are obsolete, in disrepair or not properly operated.

Covalent’s Analytical Services and Metrology Partners units are open for business and on a mission to provide and enable better, faster and cheaper data for every client.

Atomic Force Microscopy for Advanced Optical Components

New applications for optical components place ever-higher demands on surface roughness and finish specifications. Current generation atomic force microscopy (AFM) techniques provide accurate 3D images with sub-angstrom accuracy in less than a minute. These advancements make AFM ideal for applications requiring more detailed information than available with optical interferometry techniques.

Mid-Range Optical Profilometry: An Overview

Profilometry for surface characterization and dimensioning is a key area of expertise for Covalent Metrology and is proving invaluable to customers across a wide range of applications. At Covalent Metrology, profilometry covers a complete range of surface features using everything from atomic force microscopy (AFM) to optical systems to mechanical stylus systems. The purpose of this paper is to discuss the technology behind each of the three optical profilometry techniques Covalent Metrology offers and to discuss the relative advantages of each of them.
