HP-O Optical Sensors

Fast and Highly-Accurate Optical Measurements

The HP-O sensor solution is a scanning technology for coordinate measuring machines (CMMs) and is based on frequency-modulated interferometric optical distance measurement.

Non-contact measurement reaches a new dimension. The advanced HP-O optical sensor range sets new standards for optical measurements on coordinate measuring machines (CMMs) and offers customers unprecedented benefits. Of the many measurement systems and sensor technologies available, there is no other solution on the market that combines the precision, measurement flexibility and throughput of the HP-O optical sensor solutions.
Combination of the Best on the Market
Some sensors are fast, some give accessibility, others are flexible. HP-O combines all these benefits with high speed, good accessibility and great accuracy.

Flexible and Adjustable Solutions
There’s a variety of HP-O sensors, each developed to meet specific requirements. No matter how demanding the application, if it can be measured optically there’s a perfect HP-O optical sensor solution to do so.

High-Speed Scanning

With help of the interferometric laser system, a thousand points per second can be captured. This leads to unprecedented optical scanning times.

High Accuracy
The HP-O optical sensors are based on an interferometric system and are one of the most precise technologies for distance measurements on the market.

Non-Contact Measurements
The HP-O range’s non-contact optical measurement method means there is no mechanical influence on the part, eliminating wear on the stylus tip and marks on the part.
The HP-O range includes a wide variety of sensors, each one ideally suited to specific requirements.

Interchangeable fixed sensor solution.

HP-O Adjustable
Fixed sensor with unlimited styli alignment.

HP-O Hybrid
