Cost-Effective Wavefront Sensor

The HASO4 First is a Shack-Hartmann wavefront sensor optimized for single-wavelength operation within the 350–1100 nm range. It offers absolute wavefront measurement accuracy of approximately λ/100 RMS and repeatability better than λ/200 RMS. With a spatial sampling of ~100 µm and a dynamic range for local radius of curvature from ±0.008 m to infinity, it provides precise measurements for various optical applications. The sensor features a 44 x 36 microlens array over a 4.5 x 3.7 mm² aperture, enabling detailed wavefront analysis. Its compact design (42 x 47 x 60 mm) and lightweight (200 g) make it suitable for integration into diverse setups. 

High-Speed Acquisition and Versatile Integration​ 

Equipped with USB 3.0 connectivity, the HASO4 First achieves acquisition rates up to 125 Hz, facilitating real-time wavefront analysis. An optional GigE converter is available for alternative interfacing needs. The sensor operates effectively within a temperature range of 15–30°C and consumes 3.1 W of power. Its compatibility with Windows 10 and 11 ensures seamless integration into modern laboratory environments. The device also supports external TTL triggering, enhancing its adaptability in synchronized measurement systems.
