CALCULATION OF THE FIELD FROM
A BINARY REFLECTION LENS USING ELECTROMAGNETIC THEORY

A lens to focus light into a spot with the coordinates has zone boundaries derived from
Within the zones, the microrelief is binary. The results of calculation of the field from an off-axis segment of the reflection lens with a10 mm x10 mm (l=10,6mm) aperture:

a) b)
à) w=45, m=-25°, focal length f=100mm,
b) w=45, m=0° focal length f =100mm.

Advantage - this method offers a binary element with a 95% efficiency.
