the beam from the laser l passes through the shutter s, is spread by the objective lens . 激光器L發(fā)出的光束經(jīng)過快門S,被物鏡所擴(kuò)散。
Alternatively, we can image that the incoming wave is diffracted by the object and the resulting diffracted wave is then diffracted again by the objective lens . 換一種方式,我們可以這樣想象:入射波被物體反射,所得到的衍射波再一次受到物鏡的衍射。
The second arises from the spherical aberration present in the objective lens 第二個(gè)出現(xiàn)在目標(biāo)透鏡的球面像差表面。

Telescope objectives lenses 望遠(yuǎn)鏡對(duì)物鏡
Application on digital image technology in decentration measuring for objective lens 數(shù)字圖像技術(shù)在中心偏測(cè)試儀中的應(yīng)用
The viking lt 2x24 night vision binocular has a magnification of 2x and an objective lens of 24mm 維京lt2x24夜視雙眼望遠(yuǎn)鏡有一個(gè)能放大2倍的24毫米物鏡。
An eyepiece placed in the adaptor will project the prime image formed by the telescope objective lens onto the film with the resulting image magnified 在望遠(yuǎn)鏡與攝影機(jī)間的接合環(huán)內(nèi)加上一個(gè)目鏡,便可以利用目鏡將天體的影象投射至底片上。
Of course , if the disk is right at the focal length of the objective lens , then the cylindrical lens does not affect the image and it is perfectly circular 當(dāng)然,如果正好處于物鏡焦距位置,柱面鏡就不會(huì)影響到光電探測(cè)器上的成像,因而會(huì)獲得一個(gè)完美的圓性影像。
If the objective lens is closer to the compact disk than the focal length of the object lens , then the cylindrical lens creates an elliptical image on the photodetector array 如果物鏡與光盤之間的距離短于物鏡的焦距,柱面透鏡就會(huì)使在光電探測(cè)器陣列上的成像變成橢圓影像。
