Phasics innovative solution delivers the most complete lens characterization: off-axis MTF and wavefront error at multiple wavelengths. It benefits from Phasics patented technology to provide accurate results even for large Field of View (FoV). Kaleo MTF instrument is ideally suited for measuring small sets of objectives. It can be used by operators or R & D engineers to validate the design and prototyping phases. Phasics solution provides complete output from a single acquisition.


  • Single shot measurement

  • No need to realign for off-axis measurement
  • Cost effective solution
  • Several different wavelengths (RGB + IR by default)
  • Measure at several azimuths
  • Autofocus
  • Fully automated measurement process
  • Easy alignment & versatile application


  • On-axis & Off-axis MTF
  • Through focus MTF
  • Transmitted wavefront error
  • Zernike polynomials
  • Lens parameters: EFL, F#
  • OPD in the lens exit pupil
