Technical Highlights

45 nm High Repeatability

The sensor delivers repeatable measurement performance down to 45 nm, making it suitable for precision dimensional inspection and quality control.

Low Linearity Error

A linearity error of less than ±0.12 μm helps ensure accurate measurement throughout the measuring range.

Wide-Angle Measurement

With a measuring angle of up to ±60°, the sensor can measure inclined, curved, and complex surfaces more effectively.

Multiple Spot Configurations

Spot diameters of Φ5.5 μm, Φ11 μm, and Φ88 μm support different measurement requirements, including small features and larger surface areas.

Non-Contact Inspection

The target can be measured without physical contact, helping reduce the risk of scratching, deformation, or measurement interference.

Typical Applications

The sensor is suitable for a wide range of precision measurement applications, including:

Displacement and height measurement
Surface profile inspection
Thickness measurement
Curved and inclined surface measurement
Precision component inspection
Dimensional quality control
Automated inspection equipment
Industrial measurement systems

Frequently Asked Questions

What can this sensor measure?

It can be used for displacement, height, thickness, surface profile, and dimensional measurement in precision inspection applications.

Is the measurement contact or non-contact?

The sensor uses non-contact chromatic confocal measurement technology , so it does not need to physically touch the target surface.

What is the measuring range?

The measuring range is ±1.2 mm, providing a total measuring span of 2.4 mm.

What is the reference distance?

The reference distance is 9 mm, measured from the sensor to the center position of the measuring range.

Can it measure inclined or curved surfaces?

Yes. The sensor supports a measuring angle of up to ±60° under the specified test conditions, making it suitable for many inclined and curved surfaces.

How accurate is the sensor?

It provides 45 nm repeatability and a linearity error of less than ±0.12 μm.

How do I select the correct sensor configuration?

Sensor selection depends on the target material, surface shape, measuring range, spot size, and installation requirements. Please provide your application details for technical evaluation and sensor selection support .
