Optical Testing

Alter Technology is able to perform a wide variety of optical tests on components, modules and systems.

  1. Image sensors: MTF, radiation and thermal effects

  2. Solar cells and photovoltaic modules:

    • Amorphous and crystalline Si, GaAs and CIGS
    • technologies.
    • Technological characterization.
    • Efficiency and fill factor.
    • Spectral response, and V/I and C/V measurements.
  3. Light sources: power, polarization, wavelength

  4. Multimode and monomode fibres testing:

    • Electro-optical parameters.
    • Time and spectral response.
    • Environmental and mechanical specifications.
    • Constructional analysis.
    • Radiation.
  5. Diffuse light systems:

    • Characterization of led and photodiodes.
    • Optical filters and modulators.
    • Mechanical adapter and optical accessories.
    • Bare fibre adapters.
    • Laser beam-splitters.
    • Mirrors, lenses and prisms
