HIGH ACCURACY LENS UNIT The high-accuracy Ernostar lenses integrated with the sensor head achieves highly accurate and highly stable measurements.

Li-CCD*

HIGH ACCURACY LENS UNIT

Errors in pixel edges are reduced to achieve accuracy that is two times greater than conventional models.

Reducing errors caused by aberrations

Since a CCD has digital output characteristics for each pixel, the errors caused by gradual outputs generated at the edge of pixels was a barrier to higher accuracy. As a countermeasure, KEYENCE has developed an Li-CCD that outputs the position of reflected light in a pixel, achieving excellent accuracy that is two times higher than conventional models. In addition, the dedicated design of the sensor has achieved a speed that is 25 times faster and a sensitivity 10 times better than conventional models. * Li-CCD= Linearized CCD

Output of the Li-CCD

High-accuracy Ernostar lens

The measurement principle uses triangulation. The position of the reflected light on the Li-CCD moves as the position of the target changes. The displacement amount of the target is measured by detecting this change.

Principle of the Li-CCD that achieves high-accuracy measurements

Output of a normal CCD

KEYENCE has designed a new light-receiving unit for concentrating reflected light onto the Li-CCD. The newlydeveloped, 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.

DELTA CUT TECHNOLOGY Accurate reception of reflected light from a long distance is the key to high precision. KEYENCE has reviewed the cabinet design and developed a delta cut technology that reduces reflection on a filter glass surface. Comparison with conventional products

The position of the reflected light in a pixel cannot be detected. As a result, gradual changes are generated near the pixel edges, resulting in measurement errors.

The output of the adjacent pixel changes according to the position of the reflection within a pixel, providing more linear characteristics.

ULTRA-HIGH SPEED SAMPLING OF 50 kHz The Li-CCD features high-speed sampling rate 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 high-speed and high-accuracy measurements. Targets traveling, rotating, or vibrating at high speed can be measured reliably.

HIGH-ACCURACY OF ±0.02% KEYENCE has redesigned the optical system in order to achieve high-accuracy measurement. Incorporating Ernostar optical systems with a Li-CCD produces excellent linearity characteristics. It precisely focuses/detects reflection from targets to provide almost double the accuracy of conventional models. Thus, the LK-G Series is designed for product miniaturization and high-accuracy measurement.

HIGH REPEATABILITY OF 0.01 µm The CPU, which is integrated in the sensor head, digitises all signals sent 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 repeatability that is 20 times better than conventional models.

ABLE technology senses the surface of a target and adjusts the intensity of laser light to an optimal level.

The range is obtained by measuring KEYENCE’s standard target (ceramic). When the sampling rate is 20 µs, the range becomes -70 (NEAR side) to -100 mm(NEAR side) for diffuse reflection. When the sampling rate is 20 µs, the range becomes -70 (NEAR side) to -99 mm (NEAR side) for specular reflection. When the sampling rate is 20 µs, the range becomes -230 (NEAR side) to -250 mm (NEAR side) for diffuse reflection. When the sampling rate is 20 µs, the range becomes -230 (NEAR side) to -249 mm (NEAR side) for specular reflection. When the sampling rate is 50 µs, the range becomes -125 (NEAR side) to -250 mm (NEAR side) for diffuse reflection. When the sampling rate is 50 µs, the range becomes -125 (NEAR side) to -249 mm (NEAR side) for specular reflection. The range is obtained by measuring KEYENCE’s standard target (ceramic) with the Standard mode. The range is obtained by measuring KEYENCE’s standard(SUS) with 4096 times of averaging at the reference distance. All are calculated at F.S. = ±250 mm. “High accuracy range” and “long range” refer to the linearity when those ranges are used.
