Electrical Engineering, University of Costa Rica, Costa Rica.


Prof. Marín Naranjo obtained a degree of bachelor and a degree of licentiate, both in Electrical Engineering, at Universidad de Costa Rica UCR (San Jose, Costa Rica), working on fiber optics topics.

He obtained a Master of Science in Electrical Engineering at University of New Mexico, Albuquerque, New Mexico in 1990, working on semiconductor lasers for laser guided missiles.

From 1985 to 1988 he worked at ICE (Instituto Costarricense de Electricidad), the telecom company in Costa Rica, developing a training program in fiber optics for engineers and technicians for the country.

He joined University of Costa Rica in 1988, and now is senior professor in grade and post grade courses at Electrical Engineering School EIE.  His areas of interest are photonics & fiber optics telecommunications, radiometry & photometry, laser safety standards and optical metrology.

In 2000 he founded LAFTLA (Laboratorio de Fotónica y Tecnología Láser) EIE-UCR, as an academic and research laboratory on applied optics.   At present, the jobs include a joint with regional industry for the calibration of laser power and energy meters, radiance and irradiance meters from UV thru IR, photometry calibration of luminance and illuminance meters, optical fiber power meters and spectroradiometry.

At present is vice-chairman of EIE and is Chairman of Electronics and Telecommunications Department at EIE.

As been member of OSA, SPIE & LIA.   Is senior member of (Colegio Federado de Ingenieros y de Arquitectos de Costa Rica), the costarrican engineering society.   In this institution, he is chairman of the Commission on Photometry and Lighting.

He has been member of INTECO (costarrican institution for standards in metrology), on lamps and lighting.   Also he has participated in many conferences, symposia and events on Radiometry, Photometry and applied optics at NIST (USA), CENAM (Mexico) and NRC (Canada).

He has been interested in spread the knowledge on applied optics and photonics in his country, teaching in seminars and short courses.
