The high-quality optical system is designed to deliver homogenous and sharp-edged illumination resulting in bright images, a wide range of contrast and outstanding color reproduction. All telescopes are in optimized FULL HD image quality. Operational efficiency and durability are not sacrificed. The illumination fibers are fastened strain free and scopes are engineered to experience no tensile stress during the autoclaving process. Together with this and the welded outer tube, the system is sealed tight which results in a long life cycle for the optical components, resulting in low cost of ownership.
