J.A. Woollam has been the leading manufacturer of spectroscopic ellipsometers for more than 30 years.  The company is based in Lincoln, NE, and uses Covalent’s Silicon Valley facility for training and demonstrations on the West Coast.  The two parties leverage their respective strengths collaboratively to provide convenient access to world-class instrumentation and expert optical modeling in the heart of a leading US technological hub. J.A. Woollam and Covalent Metrology Services have announced a partnership to promote and further advance spectroscopic ellipsometry technology, a powerful analytical technique used to characterize advanced materials and thin films optically.

The two companies will work together on education, training, and marketing, as well as the development of new applications where the sensitivity and convenience of ellipsometry can provide key results for engineering problems. Covalent owns a fully equipped RC2 spectroscopic ellipsometer designed and manufactured by J.A. Woollam.  The system has been engineered to have the versatility required for many diverse applications. It features: a wide spectral range from 193 nm to 1690 nm, with over 1,000 individual wavelengths a fully automated 300 mm mapping sample stage for uniformity studies, a variable angle transmission stage, beam focusing down to 300 µm, and full Mueller matrix measurement capability for maximum sensitivity to challenging anisotropic samples.
