Description

E32 Precision detection

Precision detection fiber sensor heads

Highest precision in design and manufacturing of the fibers and focal lenses ensure highest beam and spot accuracy allowing the detection of smallest objects and height differences of less than 100 μm.

Coaxial fibers with focal lenses for spot diameters of 100 μm
Through-beam models with highly focused beam and precise optical axis alignment
Limited reflective models for height difference detection of less than 100 μm

Features

High production accuracy

Focused and high precision beam alignment during manufacturing. Models available with typical deviation of 0.1° for very precise detections.

Coaxial fibers

Coaxial fibers provide an enhanced positioning and detection accuracy and allow the easy adjustment of the focal point using adjustable focal lenses.

Variable focal point

Coaxial fibers allow the controlled usage of adjustable focal lenses to adjust the focal point and spot size whereas conventional multicore fibers show an unpredictable behaviour.

Limited reflective fibers

Limited reflective fibers utilize the total reflection on shiny surfaces to detect height differences or objects at a pre-defined distance.
