Abstract
A computer-controlled imaging conoscope has been used for investigation of optical homogeneity in undoped LiNbO3 crystals pulled by the Czochralski method, and also for testing of optical elements, like e.g. electrooptic modulators. The two maps acquired for two perpendicular directions in the crystal (Zoptical axis, and usually Y-axis) are utilized simultaneously for eliminating optically inhomogeneous areas from their use in optics and electrooptics, as well as in a wider research program including optimization of the growth technique and investigation of influence of crystal perfection on device performance.
