PRECITEC LR Optical Sensor
Optical sensor for ultra-precision surfaces
Adding a non-contact sensor option to the tactile probing and scanning functionality of coordinate measuring machines (CMMs), the PRECITEC LR can be automatically exchanged with tactile probes as part of a multisensor setup for a more complete measurement solution.
When tactile measuring technology reaches its limits, optical sensors can take over. Optimised for use with the ultra-precision Leitz PMM-C, Leitz Ultra or Leitz Inï¬nity CMMs, the PRECITEC LR optical sensor is particularly accurate at the submicron level. With a large acceptance angle, the sensor is ideally suited to inspecting heavily-inclined surfaces while the non-contact measurement method is perfect for fragile parts.
The PRECITEC LR provides ultra-precision measurement results independent of the type of surface, enabling inspection of dispersive, reflective, oblique, curved and aspherical surfaces.
High axial resolution
Excellent longitudinal resolution ensures good quality measurement of complex structures and freeform workpieces.
Non-contact inspection method
Touch-free measurement allows the inspection of sensitive and soft materials with no risk of scratching or damage to the workpiece surface.
Large acceptance angle
Measurement angle of 90° ± 40° allows the measurement of heavily-inclined surfaces for better part accessibility and program efficiency.
Small spot diameter
A 1.4 μm spot diameter provides high lateral resolution and enables the sensor to support optical roughness measurement.
Supports full measurement range
The measuring range of the PRECITEC LR sensor corresponds to the measuring range of the CMM, giving it the ability to measure even very large and heavy parts.
Seamless multisensor integration
With no differences in handling compared to a tactile sensor and automatic switches between the two methods possible within a measuring process, there is no additional operator burden.
