HA120Z Alignment CGH

HA120Z Alignment CGH

Our HA120Z Alignment CGH is used to optically align 120R-frame CGHs to your interferometer test beam and radius slide axis. On replacing the Alignment CGH with a Custom CGH Null, the spherical or collimated test beam is diffracted to produce a prescribed aspheric wavefront.

Specifications

The HA120Z provides 16 on-axis foci. The tables below give CGH coordinates (x,y,z) of the several transmission sphere focus locations. Grating patterns are “spherical” to about 1 fringe. Diffraction efficiency is approximately 1 percent in 3rd order.
