Tech info
Resources

LTCL4K telecentric illuminators are specifically designed to be paired with TC4K telecentric lenses, in order to provide the high optical throughput needed for high-speed line scan measurement applications involving for instance steering components, gear and cam shafts, grinding and turning parts.

These illuminators are equipped with state-of-the-art LED driving electronics, providing exceptional illumination stability, precise light intensity tuning and easy replacement of the LED source.

The unique “slim” form factor allows these units to be used in constrained spaces, often a critical factor in many industrial environments. Also, CMMR deflecting mirror accessories can be integrated to quickly assemble different illumination geometries, compatible with most type of inspection configurations.

Also, CMMR4K right angle mirror attachments can be integrated to quickly assemble different illumination geometries, compatible with most types of inspection configurations.

KEY ADVANTAGES

  • Compact design
    “Flat” shape for easy integration.
  • High optical throughput and enhanced field depth
    When coupled with compatible TC4K telecentric lenses.
  • Dedicated CMMR4K mirrors
    Right-angle deflection of the light path for usage in tight spaces.
  • Homogeneity test report with measured values.

DID YOU KNOW?

LTCL4K series is now also available with new LTSCHP1W-GZ green light source, suitable for any kind of sample and specifically tailored for measuring reflective objects and objects with sharp edges.

KEY FEATURES

  1. Reduction of edge diffraction effects
  2. Enhanced illumination uniformity, especially on large FOVs
  3. Less sensitive to alignment
