i.Terminal® 2

Another Way to collect Centration Data


With i.Terminal® 2, the latest ZEISS centration device, fitting parameters are captured digitally for advanced lens customization.

Lens fitting plays a key role in maximizing visual comfort, as fitting errors can cause up to 40% loss in lens performance. i.Terminal® 2 captures and calculates your patient´s individual parameters with the click of a button and a precision of 0.1 mm which can result in a decreased complaint rate, reduced non-adapts and relaxed vision for your patients.


  • Hightlights

    With the help of i.Terminal® 2, lens fitting becomes comfortable and enjoyable for your patients, as they see that you are willing to go the extra mile to provide the latest lens design and ensure relaxed vision.

    Capture your patient´s individual fitting parameters using the i.Terminal® 2. With the click of a button, one front and one side picture of your patient will be captured. After this, you can adjust the markers on the frame directly on the pictures and the system will calculate the data automatically for you.

  • Details

    In 60 seconds, i.Terminal® 2 can capture and calculate various fitting parameters including:

    • Frame data (A, B, DBL)
    • Interpupillary distance (PD)
    • Monocular pupillary distance (mono PD)
    • Fitting height, segment height
    • Back vertex distance (BVD)
    • Pantoscopic angle (PA)
