Typically incorporating primary and secondary hyperbolic mirrors – RC designs offer compactness, a good field of view and are free of optical errors and spherical aberrations inherent with traditional reflecting telescope optics. Benefitting from a simple two mirror design – RC telescope optics provide exceptional image quality, high thermal stability and achromatic performance from the UV to far infrared making them perfect for wide ranging surveillance applications.
Drawing upon its uniquely stable production facility – Optical Surfaces Ltd. has established itself as a leading supplier of hyperbolic mirrors up to 700 mm in diameter and the extremely tight tolerances and accuracy that these optics demand.
Dr Aris Kouris of Optical Surfaces Ltd commented “Our experienced optical engineers routinely produce hyperbolic mirrors with surface accuracies up to lambda/20 P-V, surface finish of 10/5 and microroughness of less than 1.0 nm RMS. These ultra-high precision hyperbolic mirrors can be supplied with a coating optimized for a specific military surveillance application.
