Abstract

DISPOSITIVO DE APROXIMAÇÃO/FOCO E LENTE DE APROXIMAÇÃO. Dispositivo de aproximação/foco e uma lente de aproximação correspondente, em que o dispositivo de aproximação/foco compreende um primeiro cilindro de lente de foco (101), um primeiro cilindro de lente de aproximação (102), um primeiro motor ultrassônico e um segundo motor ultrassônico, que são todos dispostos coaxialmente; em que o primeiro cilindro de lente de foco (101) e o primeiro cilindro de lente de aproximação (102) são imobilizados na direção radial e o primeiro cilindro de lente de aproximação (102) tem um diâmetro maior do que o do primeiro cilindro de lente de foco (101); os dois motores ultrassônicos são respectivamente usados para acionar os dois cilindros de lente (101, 102) para se moverem axialmente pela rotação dos rotores (103, 104). A lente de aproximação solicitada para prolongar e recolher é disposta na periferia do cilindro de lente de foco e os dois cilindros de lente são acionados pelos motores ultrassônicos e, assim, a extensão e retração da lente de aproximação, assim como o ajuste de posição de aproximação, são realizados simultaneamente; além disso, o cilindro de lente de aproximação é adequado para disposição de um ângulo de lente ampla devido ao diâmetro maior do mesmo e a estrutura de lente é gradualmente aumentada de dentro para fora, visto que um grupo de lente é montado de trás para frente e, assim, o trabalho de montagem se torna mais rápida e sem obstáculos e a miniaturização de lentes pode ser alcançada mais facilmente.
