Uses Fresnel diffraction principle with high-resolution sensors for micron-level precision. High-speed image processing, compact, durable, and with a wide measurement range. Features multi-spectral parallel laser sources for accurate and reliable imaging.

Applicable for: wire, communication cables, various pipes, rods, medical wires, and outer diameter measurement.

Fresnel diffraction principle

			When laser light passes through the measured object, it deviates from its straight-line path, resulting in diffraction. This diffraction causes alternating light and dark stripes to appear on the CCD image sensor. By analyzing the spatial distribution of these stripes, the size of the measured object can be calculated.

Compact size, large measurement range

The compact design effectively solves the space limitations posed by traditional large-sized measurement equipment.
Whether integrated into production lines for real-time monitoring or used as an offline testing tool in laboratory environments, the LIG series delivers outstanding performance.
