Excellent image quality depends on the optical material. For this reason, Carl Zeiss either selection, or in the process, have to stick with the highest standards. All prisms and lenses are using the latest research and design to ensure the highest accuracy. Optical lenses, we will carry out the ingredients precise configuration and use of the Zeiss "T * composite coating", in the optical conductivity, color performance, brightness and contrast have reached the top level, thus ensuring the telescope in have access to a wealth of high-resolution images in the whole field of view. In the field of optics, many valuable discovery, we have been directly used for the design of the telescope. A very typical example is this: We will add fluoride glass for our new series telescope victory FL models. Fluoride ion lens not only make images become clearer, but also greatly improves the color reproduction of images. Each of our telescope has waterproof, dustproof functions. High temperature resistant, cold-resistant, its use can be trusted even in harsh environments. Zeiss telescope has a long life.
