Multi-focal diffractive optical element

Holo/Or has launched a multi-focal (MF) diffractive optical element (DOE), which allows a single collimated incident beam to focus simultaneously at several focal lengths along the propagation axis.

The number of foci and the distance between them is predetermined during the design. The MF-DOE can be manufactured on a window as a general solution, for a variety of operating working distances, or as a hybrid element on a plano-convex lens for tailored solution. MF elements are mainly used for microscopy and in the laser cutting industries.
