objective symptom

It was based on the principle of laser confocal microscope . and the two - dimensional scanning configuration was adopted by the optical scanner and the telecentric linear imaging objective lens of large numerical aperture to realize x - direction ' s scanning , and the conventional mechanical method using linear driver and linear guide track to y - direction ' s . the experiment results indicate that the device can run smoothly and rapidly , be operated easily and detect fluorescence effectively 儀器基于激光共焦顯微鏡的理論,采用振鏡和遠心線性成像物鏡實現x向掃描;精密導軌和步進電機實現y向掃描的檢測儀,經驗證,掃描儀具有快速、操作簡單、檢測芯片能力良好等特征,有望彌補市場的空缺。

Whether the 180 inversion appears in the relation between the electron - optical image , i . e . the micrograph , and diffraction pattern seen on the final screen , depends on the number of inversions that the image and diffraction pattern undergo by the lenses following the objective lens in the microscope column 電子光學映像比如顯微圖和最終屏幕所見衍射模型之間180度倒置的出現是否有聯系,取決于顯微鏡柱中目標通過透鏡產生的映像的倒置數量。

This is achieved experimentally by focusing the selector aperture on the final screen using the diffraction lens , which is most accurately done after removing the objective aperture , and then ( after replacing the objective aperture ) focusing the specimen using the objective lens only 這已經通過使用衍射透鏡在最終屏幕上聚焦選擇孔實驗性的完成,此方法多數能在移動目標孔后準確完成,然后(重置目標孔后)僅通過目標透鏡聚焦樣本。

Electrons which pass through the thin specimen are brought to a focus in the back focal plane of the objective lens , this lens , like all electromagnetic lenses , acts as a converging lens and thus forms a diffraction pattern in this b . f . plane 穿越薄樣本的電子被帶到目標透鏡背面焦點平面的一個焦點,這個透鏡,象所有的電子透鏡一樣,充當了聚焦透鏡的作用,因此,構造了在這個背面焦點平面的衍射模式。

The specimen is mounted in a special holder which fits into the bore of the objective lens and enables the specimen to be tilted through angles greater than 30 about two orthogonal axes so that appropriate crystallographic analyses can be carried out 樣本被架在特殊的支架上,支架被放置在目標透鏡的圓孔中,使得標本傾斜的角度能夠超過30穿過兩個正交的角,然后適用的晶體學分析再展開。

We want to unfold the foils so that we can examine and image the tiles using transmitted illumination ( light from below the tile ) rather than reflected illumination ( light through the microscope objective lens ) 我們打算打開襯板這樣就能用透射光(光線從凝膠塊下面照過來)而不是反射光(光線從顯微鏡物鏡處照過去)照明來對凝膠塊進行檢查、拍照。

We discuss a low cost fabrication method of a diffractive microlens with high performance for both blue and red dvd objective lenses , which consists of single - step photolithography and a wet etching process 摘要采用單步光刻和濕法腐蝕工藝,低成本快速制作面向高性能藍光和紅光dvd光學頭物鏡的衍射微透鏡。

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 當然,如果正好處于物鏡焦距位置,柱面鏡就不會影響到光電探測器上的成像,因而會獲得一個完美的圓性影像。

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 在望遠鏡與攝影機間的接合環內加上一個目鏡,便可以利用目鏡將天體的影象投射至底片上。

The viking lt 2x24 night vision binocular has a magnification of 2x and an objective lens of 24mm 維京lt2x24夜視雙眼望遠鏡有一個能放大2倍的24毫米物鏡。

The second arises from the spherical aberration present in the objective lens 第二個出現在目標透鏡的球面像差表面。

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 beam from the laser l passes through the shutter s, is spread by the objective lens . 激光器L發出的光束經過快門S,被物鏡所擴散。
