Abstract

We introduce the design method of a hybrid lens composed a refractive lens and a diffractive optical element (DOE) considering the diffraction effect for a compact camera module. When imaging optical system is designed using the DOE, diffraction efficiency of the DOE and stray light due to the unintended diffraction light should be considered. Therefore, to analyze the effect of diffraction efficiency of the DOE on image characteristics, we evaluate the performances of two designed compact camera lenses, which have different construction wavelengths, using the modulation transfer function (MTF) considering diffraction efficiency. The stray light that is induced by the diffraction effect of the DOE is analyzed by calculating the focal position according to each diffraction order, and a method for the reduction of the stray light is proposed.
