Laser Optics Test


Key Features

HIGH RESOLUTION + HIGH SENSITIVITY | for shortwave infrared

The SID4 SWIR-HR wavefront sensor integrates Phasics patented technology with a high quality InGaAs detector. It ensures accurate wavefront analysis in SWIR source and lens testing.


  • Extended spectral range from 0.9 to 1.7µm – the SID4 SWIR-HR covers NIR and SWIR regions without any calibration
  • Very high resolution – 160 x 128 phase pixels
  • High sensitivity – < 2nm phase noise through the whole spectral range – the SID4 SWIR-HR is suitable to low energy IR sources
  • Compact and self-referenced for an easy set-up

R-Cube | add-on for double-pass test


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 calibrating optical test bench or the telescope in adaptive optics beamline. This illumination unit simply plugs to the wavefront sensor and delivers a very high quality collimated beam. So wavefront measurements in double pass are made easy and accurate.

Key Features

for accurate measurement

  • Ultra high quality collimated beam generation
  • High spatial resolution wavefront sensor: up to 300×400 phase pixels
  • Low noise

Plug & Play device

  • Small footprint
  • Compatible with translation and tip/tilt stages for alignment
  • Separate add-on from the wavefront sensor that can be independently used
