Design of Hybrid Refractive-Diffractive Apochromatic Telephoto Lens Used in Visible Spectra
By means of hybrid refractive-diffractive structure,a kind of three-elements telephoto lens based on two kinds of ordinary homebred glass K9 and TF3 has been designed. The working wavelength range of the system is 0.546~0.768 μm. The secondary spectrum has been revised. Its optical performances are compared with all refractive ones which are made of seven pieces of optical elements and four kinds of glass. The results show that hybrid refractive-diffractive lens can effectively eliminate the aberrance of telephoto lens and greatly reduce system length,weight,and complexity. The optical imaging and structure performances of hybrid refractive-diffractive telephoto lens are superior to all refractive system.
