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?
