Optical system and optical instrument with diffractive optical element

   
   

An optical system for forming an image of an object. The optical system includes an optical element, which is deformed by the weight thereof, and at least one optical member for preventing a change in optical performance of the optical system due to deformation of the optical element, when the optical element is provided in the optical system.

Um sistema ótico para dar forma a uma imagem de um objeto. O sistema ótico inclui um elemento ótico, que seja deformado pelo peso disso, e ao menos um membro ótico para impedir uma mudança no desempenho ótico do sistema ótico devido à deformação do elemento ótico, quando o elemento ótico é fornecido no sistema ótico.
