Ellipsometer

The J. A. Woollam Co. is a manufacturer of spectroscopic ellipsometers for non-destructive thin film and bulk material characterization. Spectroscopic ellipsometry (SE) has become the standard for measuring thin film thickness and optical constants (n and k). Spectroscopic ellipsometry is used for characterization of all types of materials: dielectrics, semiconductors, metals, organics, and more. We offer ellipsometers covering a spectral range to meet any need (from the vacuum UV to the far IR). Many upgrade options are available with our ellipsometers: automated sample translation, variable temperature (heating or cooling), focusing optics, liquid cells, etc

Ocean Optics System

Country of Origin India
Type Optical Inspection System

If a spectrometer is the heart of an Ocean Optics system, and its light source the lungs, then fibers and probes are the circulatory system the conduits through which light travels to reach the extremities and bring life to the measurement of a sample.Our patch cords come in a variety of core sizes for optimizing throughput. Bifurcated fibers and splitters are Y-shaped assemblies for routing light from one location to two others.
