High-Precision 3D Measuring Station for Measurement and Evaluation of Optical Components

• Checking topography in the first working step
• Increased flexibility
• Your results are correct

Description:

An increasingly more compact and favorable system design is demanded on optical systems such as zoom lenses, optics for DVD drives and lenses in the cameras of mobile phones, for example.

For this purpose, in addition to classic, spherical lense shapes (sphere-shaped), the optics industry is increasingly producing aspheric shaped (not sphere-shaped) lenses.

The evaluation program serves to analyze measurements on spherical surfaces with Mahr contour measuring units. Measured profiles are imported, the nominal form of the aspheres are defined and

the residual error is determined compared to the nominal form. The data is made available for readjustment of the processing machines (closed loop).

In comparison to the laser interferometer, the tactile measuring technology also allows 2D and 3D measurement of optically rough surfaces, so that testing and correction is possible already early on

in the production process (grinding).

Advantages:

The highly precise MarSurf LD120 is the basis for precision measurements of your workpieces. The vertical resolution of 2 nm and form deviations of < 100 nm guarantee you an exact reproduction of your asphere.

The complete measuring system is housed in a cabinet. The additional vibration damping decouples the measuring object and measuring system from ambient influences.
