Ellipsometers give non-contact thickness and refractive index measurements of thin transparent and semi transparent films to 1 angstrom or better. Gaertner has helped pioneer the field of ellipsometry and we offer high quality laser ellipsometers to meet varied user requirements in the semiconductor, solar cell, bio-chemical, flat panel and other thin film industries.
