The key to understanding refractive IOLs.



Based on the patented “Phase Shifting Schlieren” (PSS) method, the NIMO TR0815 measures every type of refractive intraocular lenses, whether wet or dry, monofocal, toric, multifocal or multifocal toric.

Through its advanced technology, the NIMO offers the highest resolution amongst all commercially available power-mapping instruments, providing power and full wavefront characterization with matchless repeatability and reproducibility. Routine calibrations are no longer necessary and the software offers a user-friendly interface with plenty of options and full traceability.

Key characteristics:

  • Measures monofocal, toric, multifocal, multifocal toric lenses IOLs and more with the exact same hardware
  • Automatic marks detection for torics (TLMD) with assessment of the angle error between marks and cylinder axis
  • High-resolution power maps and power profiles
  • Rapid data acquisition – complete assessment of the most complex refractive IOLs in just a few seconds
  • Dynamic range -100D to +100D
  • Easy integration into automated production lines
  • One time calibration
  • Fully automatic Toric IOL measurement
  • Dry or wet measurement
  • Full customization program available
