ILC3 and ILC4 Objective lens changer / Linear turret
Elevate your inspection workflow with ILC, where performance and affordability come together. ILC is designed for high-demand optical inspection and FPD/semiconductor fab systems. It allows efficient imaging by quick, stable, and reliable lens switching by utilizing proven-reliable stepper-ball screw-encoder motion system.
Compare to any lens switch solution in the market, it is lighter and adds minimum distance to the optical path, which allows maximum field of view. Compare to the shaft servo motor system, it is much less sensitive to the external vibration and force, so it is quicker to settle and reliable in variety of conditions. Compare to rotary turret, it is lighter and quicker, and retains higher repeatability over longer life.
