Adaptive Optics Engineering

Lexitek offers these unique products for Adaptive Optics engineering:

Well-characterized pseudo-random phase plates (81k) download Acrobat

Each phase plate can have a unique design at no additional cost. Some options: pseudo-Kolmogorov designs from Lexitek characterized by r0, Zernike polynomials, or your own design. Some examples are shown here.

Motorized rotary stages in two sizes and several speeds

Inexpensive stepper motor controller

These tools used in combination allow the Adaptive Optics engineer to simulate multi-layer atmospheres, each with independent pseudo-wind, in the laboratory. Lexitek products offer an affordable solution for various inspection tasks and optics testing.

The most common phase plate we manufacture is a 100 mm diameter part with annular geometry, shown in the datasheet. We also make smaller and larger parts as well as different geometries. This paper has more information about our pseudo-random phase plates:

We offer flexible phase plate geometry including multiple annular regions (different r0s) or multiple circular regions (or another shape).
