The HASO4 Broadband from Imagine Optic is a Wavefront Sensor that operates at a wavelength of 350 nm - 1100 nm. It has a repeatability of up to lambda/200 (RMS) and spatial sampling of 100 μm. This wavefront sensor has an absolute wavefront measurement accuracy of 6 nm (350 nm - 600 nm) & lambda/100 (600 nm - 1100 nm) and a local radius of curvature from ± 0.008 m to ± infinity. It has an aperture of 6.9 mm x 5.1 mm and 68 x 50 microlenses. This wavefront sensor has a maximum acquisition frequency of 58 Hz or 30 Hz and minimum detectable power of 0.15 nW.

The HASO4 Broadband features the new SpotTracker&trade technology and includes an external TTL triggering. It supports the Windows 10 & 11 operating system & WAVEVIEW metrology software and has an optional SDK. This wavefront sensor can be controlled via USB 3.0 or an optional GigE converter interface. It dissipates a power of 3.1 W and is available in a package that measures 60 (L) mm x 47 (W) mm x 42 (H) mm and is ideal for optical metrology, microscopy & laser diagnostics applications.
