ZEISS VISULENS lens measurement

Intelligent measurement.

Shack-Hartmann sensor and UV spectrometer for precise information.

Four measurement modes for a wide range of lenses

  • Standard mode for single vision and multi-focal lenses for tinted and untinted lenses
  • Progressive lens mode for tinted and untinted lenses
  • UV transmission measurement mode
  • Contact lens mode for soft and hard contact lenses

Wavefront technology for precise lens measurement

The built-in Shack-Hartmann wavefront sensor performs state-of-the-art measurement based on the values of 81 measurement points. The green LED (545 nm) supports measurement of high indices and makes adjustment of the Abbe number redundant.

Intelligent measurement

Wide spectrum UV measurement

lensmeter UV spectrum mode

UV spectrum mode for detailed insights

The integrated UV spectrometer analyzes UV protection of lenses in a wavelength measurement range from 365 to 480 nm.

lensmeter UV protection mode

UV protection level mode for easy patient education

With this insightful advantage, you can identify lenses without sufficient protection and identify high quality lenses.

Intelligent alignment support helps to position the lens

Convenient operation.

Intuitive, fast and easy to use.

  • The intelligent alignment support on the screen, the built-in marking system and the pupillary distance measurement let you easily position and mark the lens.
  • The well-structured software together with a tiltable 7” color touch screen enables intuitive and fast operation.
  • The user interface nicely navigates you through the single working steps, from measurement to printout or data storage.
  • An added option allows you to set-up user profiles suiting your individual needs.
VISULENS practice workflow

Enhanced workflow.

Convenient practice integration and meaningful reports.

The direct LAN and serial connectivity options support a fast data transfer between ZEISS VISULENS 550 and practice management systems including ZEISS FORUM and ZEISS i.Com mobile / VISUCONSULT without transcription errors. Valuable time can be saved by connecting to the ZEISS subjective refraction unit.
