ULTRA LONG DISTANCE - LK-G502/G507 Series

Ultra-high Speed Sampling of 50 kHz

[All Models: LK-G10/15/32/37/82/87/152/157/402/407/502/507]

The Li-CCD features high-speed sampling 25 times faster than conventional models. High-speed digital processing of signals from the Li-CCD is performed by a special waveform-processor (Digital Signal Processor), satisfying both highspeed and high-accuracy measurements. Targets traveling, rotating, or vibrating at high speed can be measured reliably.

High Accuracy of ±0.03 %

[Models: LK-G10/15]

KEYENCE has redesigned the optical system in order to achieve high-accuracy measurements. Incorporating Ernostar optical systems with a Li-CCD produces excellent linearity characteristics.

Measuring the thickness of a silicon wafer.

High Resolution of 0.0004 Mil (0.01 µm)

[Models: LK-G10/15]

The CPU, which is integrated in the sensor head, digitizes all signals to the controller, dramatically reducing disturbance noise. A highly rigid die-cast body is used to reduce deviations caused by temperature changes, and a Li-CCD with 10 times better sensitivity than conventional models is used to reduce signal noise. These design revisions, targeting high accuracy applications, have successfully produced a resolution that is 20 times better than conventional models.

High-accuracy Lens Unit

Reducing errors caused by aberrations

KEYENCE has designed a new light-receiving unit for concentrating reflected light onto the Li-CCD. The newly-developed, high accuracy Ernostar lens drastically reduce spot distortion caused by aberrations. In addition, a special die-cast housing integrating the sensor head with the lenses is employed, achieving excellent rigidity.
