PublicationsUltraviolet Wavefront Sensing
Imagine Optic’s HASO DUV is a Shack-Hartmann wavefront sensor specifically engineered to meet the growing demands of ultraviolet spectral range applications. A key advancement in this sensor is its SpotTracker technology, which delivers absolute wavefront sensing and precise tilt information, effectively making the alignment process straightforward. This sensor integrates the accumulated expertise from Imagine Optic’s three decades of innovation and customer feedback, resulting in a device that is remarkably easy to use (thanks to its absolute measurement capability derived from embedded factory calibration), exceptionally high performing (achieving an accuracy of RMS with a very large dynamic range), and remarkably robust (maintaining phase measurement stability despite beam intensity fluctuations, offering achromatic performance across its calibrated spectrum, and remaining insensitive to vibrations).
Features
HASO DUV packs:
- Accuracy of λ/100 RMS permitting small defects detection
- Dynamic range of superior to 1000 λ for direct wavefront acquisition of converging and diverging beams
- Spectral range in the UV including 405nm for easy setting of the sensor
