Phaseview has announced the launch of digital wavefront sensors (DWS), designed for demanding applications in optics, laser beam analysis and ophthalmology, at Photonics West 2009 in California, US.
The DWS sensors deliver fast and reliable evaluation of wavefronts with high performances at any wavelengths.
They measure wavefronts with a resolution of typically 360,000 points, only limited by the resolution of CCD sensors.
With 600 x 600 measurement points available, DWS yields wavefront measurement with l/100 accuracy and l/200 sensitivity while attaining dynamic range of 1500l for the wavelength range between 350nm and 1100nm.
For laser beam measurement, DWS is used to obtain high-resolution intensity and wavefront images of the propagating beam at one location on a 1M pixel CCD array camera.
From the one-shot intensity and phase measurements and numeric propagation the laser beam is obtained at >10 positions.
The instrument is suitable for measurement of both CW and pulsed lasers down to single-shot rates, and provides quantitative measurement of M2 parameter and numerous other beam spatial characteristics.
Beam diameters are obtained with accuracy to better than two per cent, which translates to M2 measurements with accuracy to better than four per cent.
Powered by DWS, the Phaseview Wavegauge instrument is ideally suited for testing aspheric lenses with diameters from 3mm to 8mm.
With 250,000 measurement points and repeatability of l/1000 and accuracy of l/100 over entire tilt dynamic range 1500l and in real time (measurement frequency of 15Hz), Wavegauge offers reliable quality control on-line and improves productivity by saving production cost.
The new Phaseview SurphaseHS sensor allows fast 3D measurement for the shop floor or in line production.
Roughness with Ra below 1nm or profiles up to 500 um height can be measured in less than one second for 1M measurement points, with high accuracy and repeatability.
Phaseview offers both turnkey and OEM versions to ease integration in automated inspection systems.
The 3D optical instrument comes in a smart light-weight packaging, is insensitive to vibrations and can be put to use in any industrial environment.
The total measurement and processing time for an area of 2 x 2mm does not exceed two seconds.
With axial range up to 500um, axial repeatability of 10nm is achieved.
Roughness from 0.1 to 3um can be measured.
Areas of up to 100 x 100um can be measured and processed with enhanced software stitching capability.
