TCZR series is a leading edge optical solution for imaging and measurement applications requiring both the flexibility of zoom lenses and the accuracy of fixed optics.

By means of a very accurate mechanism, these lenses ensure unequaled magnification, focusing and image center stability when switching from a magnification to another, thus avoiding recalibration at any given time.

Four different magnifications, featuring a total range of 8x, can be selected either by means of the onboard control keyboard or via computer through a specific remote control software.

Bi-telecentricity, high resolution and low distortion make these zooms able to perform the same measurement tasks as a fixed magnification telecentric lens.

KEY ADVANTAGES

  • Perfect magnification constancy
    No need of re-calibration after zooming
  • Perfect parfocality
    No need of refocusing when changing magnification
  • Bi-telecentricity
    Very accurate measurement is possible
  • Excellent image center stability
    Each magnification maintains its FOV center
  • Full motorization control
    Zoom magnification can be set either manually or via software

Notes

  1. Working F/#: the real F/# of a lens when used as a macro. Lenses with smaller apertures can be supplied on request
  2. Maximum slope of principal rays inside the lens: when converted to millirad, it gives the maximum measurement error for any millimiter of object displacement
  3. At the borders of the field depth the image can be still used for measurement but, to get a very sharp image, only half of the nominal field depth should be considered. Pixel size used for calculation is 3.9 μm.
