Abstract
Hybrid lensese with both refractive and
diffractive surfaces become a promising
solution in different applications. Here we
will demonstrate an example on a hybrid
eyepiece, in which a diffractive lens
surface is used to correct chromatic
aberration. The initial design is taken from
Zemax OpticStudio® and imported into
VirtualLab Fusion for further investigation.
The modeling can be done either based
on the desired wavefront phase
response, or with the actual diffractive
surface structures (either in continuous or
quantized way) considered.

plane wave
− wavelength (486, 587, 656) nm
− field of view (40)°
− linearly polarized along x-axis
− aperture 5 mm × 5 mm
diffractive lens
− wavefront phase response
− actual diffractive surface structure
How to model a hybrid lens system with diffractive
surface, either as wavefront phase response, or with the
actual surface structure considered?

originally designed with Zemax
OpticStudio® using a Binary 2
