Optical Instrumentation

Claudio Narciso Ramírez

Claudio N. Ramírez holds a PhD degree in Optical Sciences from Centro de Investigaciones en Optica in Leon, Mexico. His research work was Design and Implementation of a Vectorial Shearing Interferometer with adjustable sensitivity. In 2012 and 2013 he worked as visiting lecturer in Physics department in Universidad Autónoma de Barcelona. In the optics group, he evolved a polarimetric method to describe the phase retardance as a function of applied voltage in spatial light modulators based in liquid crystal. Later he designs a point diffraction interferometer using a liquid crystal monopixel. From 2014 to 2016, he made a postdoctoral stay in the optics group at the Universidad Autónoma de Barcelona. His research work was based on the application of spatial light modulators to study wavefronts from aspherical surfaces. He designed and build a common path interferometer based on double sideband filter, to perform wave front reconstruction.

Currently, he is in the National System of Researchers (SNI I).

Since 2017, he is a Research Associate in the Institute for Applied Sciences and Technology (ICAT) at National Autonomous University of Mexico (UNAM). He teaches Optics, waves and optics, and Optics Laboratory at the Faculty of Sciences in UNAM.
