Description
General Introduction: Raytek's 650-1000 nm antireflection film precision polished aspheric lens has been optimized by computer, and the optical performance of diffraction limit can be achieved at high numerical aperture without multiple elements. This can be used to reduce the weight, complexity and cost of the optical system.
