What is a wavefront sensor?

Optical wavefront sensor The HASO wavefront sensor (Shack-Hartmann type) obtains the local slope of the wavefront through a microlens array. From this information, light intensity, phase, aberration, PST, MTF, and other parameters can be measured in real time.

The intensity and phase of the analysis beam HASO can be used to analyze lasers, laser diodes (LDs) and other coherent or incoherent sources. It can be used to measure wavefront, aberration, convergence angle, divergence angle, waist size/position, M2 Ratio to Strehl.

HASO application component and system characteristics

Planar components with a hole size of 5-12 mm can be measured, and larger or smaller components can be measured and analyzed with a diverging or converging beam.

Optical assembly and adjustment

When the assembly is tilted and positioned, the operator can observe the wavefront of the optical system in real time. The 3rd order aberration can be removed during the adjustment process.

Active and adaptive optics

Real-time wavefront correction can be as accurate as 1/10 to l/20 pv. Plug-In type DLLs can interact with any actual and adaptive system.

Monochromatic and incoherent sources。

Perform monochrome wavefront analysis.
