AOTECH emerges as a spin-off of the Applied Photonics group of the University of the Basque Country.

Our purpose is to apply optical solutions to all kinds of industrial processes.

AOTECH - Soluciones ópticas a todo tipo de procesos industriales

Our main product is a VIS-NIR spectroscopy platform that allows analysis of the composition of different fluids and solids in real-time.

Furthermore, we have developed a system based on optical sensors for monitoring turbines and compressors based on the measurement of tip timing (TT) and tip clearance (TC).

Currently, we are developing sensors for the measurement of dynamic pressure and measurement of high temperatures.


Our systems, based on optical sensors, will offer solutions to different markets:

  • Aeronautics
  • Food / Pharma
  • Water
  • Automotive
  • Metallurgy
  • Chemical
  • Environment ...


We are located in Bilbao, from where we have established contacts with all types of national and international companies.


We actively participate in numerous events such as congresses, workshops, ... both nationally and internationally.
