HASO4 SWIR Wavefront Sensor
The HASO4 SWIR is a Shack-Hartmann wavefront sensor optimized for the short-wave infrared (SWIR) spectrum, covering wavelengths from 900 to 1700 nm. Utilizing an InGaAs camera, it delivers absolute wavefront measurement accuracy of λ/100 RMS and repeatability of λ/200 RMS. With a spatial sampling of approximately 232.5 µm and a dynamic range for local radius of curvature from ±0.017 m to infinity, it ensures precise measurements for various optical applications. The sensor features a 40 x 32 microlens array over a 9.30 x 7.44 mm² aperture, enabling detailed wavefront analysis. Its compact design (75 x 78 x 63 mm) and lightweight (250 g) make it suitable for integration into diverse setups.
Advanced Features for Enhanced Usability
Incorporating SpotTracker™ technology, the HASO4 SWIR provides absolute wavefront and tilt information, eliminating the need for manual alignment and simplifying integration into optical systems. The sensor supports USB 3.0 connectivity with a maximum acquisition frequency of 150 Hz and offers an optional GigE converter for alternative interfacing needs. Its compatibility with Windows 10 and 11 ensures seamless integration into modern laboratory environments. For applications requiring ultra-short exposure times, the Gated version allows exposure times down to 100 ns, facilitating synchronization with pulsed lasers.
