Similar to laser micrometers, optical micrometers are thrubeam sensors that measure any object that blocks the light passing from the transmitter to receiver. KEYENCE’s optical micrometers come in single-axis, mutli-axis, or 2D models (that create 2D backlit images). Measure diameter, gap, and width with high accuracy.
High-performance optical micrometers deliver the speed and accuracy required for dynamic measurement of diameter, gap, and width. This LED based micrometer offers improved durability over a typical laser micrometer. Single and multi-axis options are available.
Performs in-line 2D measurements with high speed and precision. The TM-3000 Series is the industry's first 2D measurement system designed for use in process.
Measure diameter, gap, and width without touching the target. This cost-performance model is ideal for simple inline or offline measurements. Like the LS-9000, this system uses an LED design that minimizes maintenance and improves lifespan over a conventional laser mic.
IG Series multi-purpose CCD laser micrometers provide high-precision differentiation that is unaffected by how much light the target transmits. This series uses a line-charge coupled device (L-CCD) as its light receiving element. Instead of using received light intensity, it captures the edge of transmitted laser light, so it can perform high-accuracy, stable differentiation with 5 μm repeatability and ±0.1% linearity. This makes the IG Series capable of supporting various applications, including edge detection and positioning of clear glass, precise recognition of workpiece OD, feedback control while detecting a sheet edge, and roll gap measurement. The positioning monitor on the main unit facilitates optical-axis alignment when starting up a line and during changeovers.
