80nm Chromatic Confocal Displacement Sensor

High-Precision Confocal Displacement Sensor

The SFS-D1504 confocal displacement sensor is designed for high-precision non-contact measurement in industrial automation and precision inspection systems. It provides stable measurement performance with 80 nm repeatability, ±0.75 mm measuring range, and linearity error less than ±0.3 μm.

Compact Probe for Flexible Installation

With a compact Φ8 × 68.8 mm probe body and only 23 g weight, this sensor is easy to integrate into limited installation spaces, automated equipment, and precision measurement fixtures.

Key Advantages

• 80 nm repeatability for stable high-precision measurement
• ±0.75 mm measuring range for micro-displacement inspection
• Less than ±0.3 μm linearity error for reliable measurement accuracy
• Φ20 μm spot diameter for small target detection
• Compact Φ8 mm probe design for easy installation
• Non-contact optical measurement, no damage to the measured surface

Typical Applications

This sensor is suitable for displacement measurement, thickness inspection, height measurement, step height detection, surface position inspection, glass measurement, electronic component inspection, precision parts inspection, and automated quality control .

Industrial Inspection Solution

The confocal measurement method enables accurate and repeatable measurement without touching the target object. It is especially suitable for high-precision inspection of small parts, reflective surfaces, transparent materials, and delicate workpieces.

For production-line measurement projects, this sensor can also be combined with in-line inspection measurement systems to support automated inspection and process control.
