Applications

SpotOptics can provide turn-key solutions for quality control of almost any optical element and lasers.

Our instruments can test at UV, Visible, SWIR, MWIR and LWIR (CO2) wavelengths. The test can be either in reflection or transmission. We have several successfully installations in the industrial world and in research.

According to your requirements, we can study customized solutions for your specific application. We can also integrate special hardware in our systems or develop special analysis software.

Head-up display test with Omi

SpotOptics developed the system for testing the Heads-Up Display (HUD)  in the production line for a German company working in the automotive industry. SpotOptics wavefront sensor Omi and Shack-Hartmann analysis software Sensoft were used to get the quality of the system.

Testing lenses with Optino: measure stress due to lens mounting

SpotOptics Shack-Hartmann wavefront sensor Optino and  Sensoft software were used to test an ophthalmic lens held in a 3-point clamp.

Output results from Sensoft analysis are the table with the Zernike coefficients  (at left in the figure below) and several graphs.

An important feature in Sensoft is the wavefront map reconstruction. This means that the user can select and see in the map the effect of any aberration(s).

  • In the example given above (see figure above, wavefront at left), Defocus, Tilt and Astigmatism were mathematically removed in the map. The typical 3-point structure of Triangular Coma (213 nm) is quite evident in the wavefront . The conclusion is that the 3-point clamp generates stress in the lens. The relevant amount of Astigmatism and Triangular Coma is the consequence of this.
  • When removing the 3-point clamp Astigmatism is much smaller and Triangular Coma is negligible (see figure below).

 

Astronomical telescope test with Puntino: measure stress due to supports

SpotOptics wavefront sensor Puntino and Sensoft software were used for analyzing a 1.5m mirror telescope in 1996. Since the Telescope has an annular pupil, the Annular Zernike polynomials were implemented in Sensoft together with the Standard Zernike, Fringe Zernike and Seidel polynomials. After the calculation of the Annular Zernike aberration terms, the wavefront was reconstructed mathematical removing all of the Zernike terms (this is a feature of our software Sensoft): the resulting mirror surface map (left) clearly follow the mirror support map (right).
