2. Finally, the aspheric lens system was processed by single point diamond turning techniques and its shaping ability was tested by the optical analyzing software.

3. Imagine that we have some sort of Lens system which forms an image of an extended object.

4. MEGA OIS hand - shake and the lens system shifts to compensate, helping to prevent blurry images.

5. Fresnel lens system design was the first try and a commercial Fresnel lens was bought to analyse its model to use at the same time.

6. Waveguide to be fitted - the first acoustic lens system ever fitted to a Dual Concentric.

7. The position of the image and the amplitude variation in the optical field are associated with the focus and the distance from the object to the front focal plane of the lens system.

8. Conclusions: Scanning laser ophthalmoscopy and angiography with a wide-field contact lens system have important application value on the choroidal melanoma diagnosis.

9. One is prepared by overlapping two line-type zone plates. It acts as a two-cylindrical lens system.

10. The achromatic principle and its design method of two-grating lens system are presented.

11. The camera system contains not only the detector but also , and very importantly,(Sentencedict) a lens system.

12. An all-electrostatic focusing and deflecting system characterized by simple lens system is introduced The new system is very useful in producing compact high-performance camera tubes.

13. In the present study, an aberration theory for both wide and narrow electron beams in a combined electromagnetic focusing spherical cathode lens system is discussed.

14. Even the simple trilobite has an eye (complete with its double lens system) that's considered an optical miracle by today's standards.

15. As before, the laser package is hermetically sealed for reliable operation in adverse environments and the laser output is collimated using an internal lens system.

16. September 2, 2009: Panasonic has added a powerful new model, the DMC-GF1, to its LUMIX G Micro System lineup of next-generation digital interchangeable lens system cameras.

17. In this paper three-dimensional object field can be transformed into three-dimensional image field by the 4F Fourier lens system according to the theory and experiment.

18. In this paper, the specialized techniques of electron gun for large screen CPTs are discussed. The beam forming region, main lens, convergence lens system and dynamic focusing method are analyzed.

19. To study the structure of telecentric beam path for zoom lens system, the axial displacement equation for the stop was deduced, which keep the system telecentric in all zoom position.

20. The principle and method of holographic record of the particle field by 4F Fourier lens system and holographic filter are introduced in this paper.

21. The stereo projector by polarized light include chiefly. the three parts: the objective lens system of the projection, the condensing system and a source of light.

22. It adopts the imported MRF CO2 laser tube, the best expanding lens system and high scanning head.

23. The graticule image was projected through a prism and a stadiametric lens system onto the windscreen, and a dimming rheostat was fitted close to the unit on the instrument panel.

24. The eye-in-hand vision system is an important type of robotic vision system. In this paper an inverted-telephoto lens system which serves as eyes of robot is discussed .

25. The condenser is equipped with an iris diaphragm , a shutter controlled by a lever which is used to regulate the amount of light entering the lens system.
