- Lenses up to diameter 15 mm (without additional optics)
- Surface topography measurement up to 7° deviation from the sphere (with optional reflex module)
- Compact and robust design
- Flexible wavefront measurement in the laboratory and in production
- Integration into existing laboratory or production facilities
- Communicates WaveMaster® software via CameraLink or IEEE 1394b
- Sensor configuration
Applications
Range of applications of Shack-Hartmann sensors:
- Measurement of the wavefront (PV, RMS)
- Determination of the Zernike coefficients
- Measurement of the Point Spread Function (PSF)
- Measurement of the Modulation Transfer Function (MTF)
- Measurement of the Strehl ratio
- Wedge angle
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
