Key Features


  • Image quality evaluation of any existing lens system: infinite, finite, afocal
  • Measurement of the modulation transfer function (MTF) off-axis and on axis
  • Modular and upgradable design
  • Quick exchange of different modules within a few minutes (e.g. changing from VIS to IR)
  • MTF values tracable to international standards
  • Perfectly aligned measurement heads using proprietary alignment procedures
  • Cover for diffraction limited collimators to avoid ambient light and air turbulences
  • Innovative and time saving IR area sensor method
  • Years of experiences and from a high diversity of customers
