Phasics R-Cube illumination module for SID4 wavefront sensors

The R-Cube is an add-on for easy double-pass measurement with Phasics' wavefront sensors. It applies to mirror and large-lens aberration measurement and helps with calibrating optical test systems or the downsizing telescope in adaptive optics. This illumination unit simply plugs into the wavefront sensor and delivers a very-high-quality collimated beam. Wavefront measurements in double pass are made easy and accurate.

Key Features

  • Ultra-high-quality collimated beam generation from UV to SWIR
  • Small footprint, easy to integrate
  • Separate add-on for the wavefront sensor that can be independently used


Laser testing, adaptive optics, and plasma diagnostics Optics metrology and optical system alignment
