Abstract
This paper presents a technique for calculating hybrid objectives for spectral optical coherent tomography. A formula is obtained for determining the parameters of a kinoform that is the basic element of a hybrid objective that contains the kinoform and a lens part. Layouts are shown for hybrid microscope objectives with focal lengths of 32 mm and 16 mm and apertures of 0.2 and 0.4, respectively, operating in the wavelength ranges 1.26–1.36 μm and 0.8–1.0 μm. The objectives possess diffraction quality of the image.
