WaveMaster® Plan - Wavefront Measurement of Planar Elements
The WaveMaster® Plan is used in the quality control of planar optical elements such as plane plates or wedges.
The system uses its integrated Shack-Hartmann sensor to measure the wavefront of the samples in transmission
Wavemaster Plan measures plane elements with Shack Hartmann sensors
Key Features:
- Comprehensive analysis of planar optical elements
- Rapid measurement speed for high sample throughput
- Sample holder for alignment in the submicron range.
- Only minimal realignment of samples is required for wavefront measurements of sample series.
- High measurement accuracy of the Shack-Hartmann sensor
- Real-time comparison between wavefront data and sample lenses or design values
- Collimated light source
- Vibration-resistant design
- Comprehensive software functions for measurement and analysis
- Simple and rapid measurement of planar elements. If adjustment is needed, then only center the sample roughly on the sensor.
Applications
WaveMaster® Plan measures the wavefront of plane elements in transmission.
Wavefront Measurement with Shack-Hartman Sensors
The WaveSensor® software is clearly structured, easy to use and contains all functions to measure and analyze plano, spherical and aspherical samples with the WaveSensor®.
The software communicates with the Shack-Hartmann sensor and analyzes the measured wavefront in real time.
Advantages:
- Menu-driven operator guidance
- Simple and intuitive measurement and analysis of wavefronts and surfaces
- One software package for everything: Data collection, data calculation, calibration, display of data, real-time analysis
- Load theoretical data from ZEMAX and Code V and compare in real time during measurements

Upgrades & Accessories
The wavefront instruments are characterized by a flexible design which allows for the adaption of the instruments to specific demands of an application. With the help of the following accessories and upgrades the function of the WaveMaster® systems are extended.
Wavefront Sensors:
When higher dynamic range or accuracy is required the wavefront sensors of the WaveMaster® instruments can be exchanged. All available WaveSensor® devices can be implemented into the WaveMaster® instruments as an upgrade. Further wavefront sensors are offered on request.
Illumination
Light sources with different wavelengths are available.
Telescopes
For maximum utilization of the sensor dynamic range and thus the lateral resolution a set of telescopes is available.
Depending on sample diameter and wavefront sensor dimensions the optimum magnification has to be selected. The kinematic mount allows for easy exchange of the telescopes.
