About ESDI

ESDI is a world-class developer of metrology instrumentation and software - serving companies of all sizes, major research laboratories, and universities worldwide. ESDI offers state-of-the-art metrology products that are both affordable and unprecedented in performance.

ESDI develops and customizes its products with our customer’s most challenging applications in mind. ESDI products range from the economical to the highest performance systems available. Startup companies can truly afford to equip their labs with the latest, state-of-the-art metrology equipment such as the Dimetior PS traditional Fizeau Interferometer. At the top of the ESDI product line, are the Dimetior VB Simultaneous Phase-Shifting Interferometer and the Dimetior AS for measuring aspheric surfaces. The Dimetior VB offers true vibration insensitivity, dynamic measurements, and is truly in a class of its own. Measurements in the most rugged environments including vibration, turbulence and small space constraints are a simple task with the Dimetior VB. The Dimetior AS is the most advanced of all ESDI interferometer systems as it allows for the noncontact measurement of aspheric surfaces, both rotationally symmetric and asymmetric, in a single shot. This is accomplished with ESDI’s patent pending CGR technology and does not require null optics, CGHs, stitching, or vertical scanning.

ESDI’s IntelliWave™ interferometric acquisition and analysis software is used in many industries, and is widely considered the #1 interferometer independent software package on the market. ESDI’s Dimetior interferometers are crafted around the flagship IntelliWave™ interferometric software platform. The combination of advanced hardware and software results in the widest range of wavefront measurement products available from a single company.
