S0.- Advice and requirements analysis

Advice to companies and other research groups for optical devices conceptualization, requirements and preliminary technical specifications. Evaluation of the viability, identification of possible critical points and analysis of alternatives. The result is a technological pre-diagnosis in which the above information is detailed together with a temporary planning of the required services and a cost calculation.


S1.- Optical design and simulation

Design and optical simulation for the detailed evaluation of the technical feasibility of the conceptual designs before their physical implementation. Diffferent software tools are used to perform the following functions:

  • Sequential and non-sequential optical design
  • Photometric simulation
  • Opto-electronic devices response simulation
  • Optical and mechanical tolerances analysis
  • Analysis of manufacturing feasibility


S2.- Mechanical design

Design of opto-mechanical components by means of CAD as well as other mechanical elements necessary for the correct operation of optical and photonic devices.


S3.- Design and development of acquisition, processing and control electronics.

The design of electronic systems in the field of photonics is focused on two complementary fields:

  • Acquisition and processing of analog signals from sensors of different technologies.
    1. Design of precision analog electronics from the theoretical idea to the functional prototype through all stages of development: selection of materials, diagrams, validation tests, mounting on plates manufactured by CNC, field tests, integration with microcontrollers for processing or shipping to high-level systems and, finally, industrial manufacturing prototypes.
  • Reception and processing of information obtained from integrated systems that serve sensor data through digital communication buses.
    1. Design of intercommunication systems and pre-processing from the theoretical idea to the functional prototype, analyzing in depth the different physical media and protocols involved and selecting the most appropriate 32-bit microcontroller-based system. Processors included, but not limited to: Texas Instruments, Microchip, ST, and Espressif families; protocols based on Ethernet, SPI, RS-485, Ethercat, RS-232, USB, etc.


S4.- Manufacture of optomechanical components

Manufacture by means of a conventional lathe and milling machine of mechanical components with standard accuracies (0.1mm). The materials used are aluminum, bronze or machinable plastics (Delrin, PEEK, ...). The size of the pieces is limited to 300mm.


S5.- Validation and characterization of components and complete devices

Radiometric, photometric, colorimetric and spectrometric characterization of the spectrum of light emitting sources and components included in the devices. Verification of the specifications of the complete devices at the radiometric / photometric / colorimetric level and in the corresponding areas of the electromagnetic spectrum (near infrared, visible and ultraviolet ranges). Dimensional and finish verification (roughness, texture) of the optomechanical components before the integration of the devices. Characterization of optical components (optical quality, aberrations, resolution tests, etc.).
