An analytical approach is presented for determining the characteristic
s of the zones of a planar kinoform lens of any specific order for sti
gmatic imaging between extra-axial conjugate points. It is shown that,
by use of a suitable normalization, the zone characteristics are obta
ined in terms of dimensionless variables. This facilitates ready estim
ation or comparison of pertinent zone parameters in given applications
. The convenient amenability of the approach to the case of reflective
kinoform lenses is also indicated. (C) 1995 Optical Society of Americ
