Laser system alignment

SID4 wavefront sensors bring a lot of advantages to perform optical system alignment. First, the SID4 range covers a large set of wavelength spectrums: UV, visible, NIR, SWIR, MWIR, and LWIR. Second, the SID4 is compact and easy to align which makes the measurement straightforward to put in place. Last, the high resolution, large dynamic range, and nanometric sensitivity ensure an accurate and robust wavefront qualification. The Phasics SID4 wavefront sensors offer the best solutions to engineers, researchers, and manufacturers for optical system alignment and qualification in R&D and production environments.

Leverage the ease of use of SID4 wavefront sensors to master optical systems alignment

Optical system collimation

For optical system collimation, it is straightforward to monitor the defocus Zernike term, the divergence of the beam and the radius of curvature, live on the SID4 software.

Afocal telescope alignment in single pass

Using the live calculation of the wavefront Zernike or Legendre polynomials, it is possible to finely optimize the alignment of afocal telescopes. Measurement can be performed in single-pass or double-pass (see next figure) configurations with the help of the R-Cube self-illuminated source module.

Telescope alignment in double-pass configuration.

Off-axis parabola alignment

Thanks to the SID4's unique capability to measure a diverging beam without a relay lens and the live calculation of the wavefront aberrations, the SID4 can be used as a tool to ease the alignment of complex components such as off-axis parabolas.
