objective lens उदाहरण वाक्य

उदाहरण वाक्य

1. The magnification is equal to the focal length of the objective lens divided by the focal length of the eyepiece.
2. It represents the distance at which the mirror or objective lens will cause light to converge on a single point.
3. Telescopic sights are classified in terms of the optical magnification and the objective lens diameter, e . g . 10?0.
4. The improvement in resolution is achieved by using two opposing objective lenses, which both are focused to the same geometrical location.
5. In the ideal case each objective lens can collect light from a solid angle of \ Omega = 2 \ pi.
6. So, with two objective lenses one can collect from every direction ( solid angle \ Omega = 4 \ pi ).
7. The image from the objective lens is focused on a narrow slit revealing only a thin portion of the suns surface.
8. The correct immersion oil for an objective lens has to be used to ensure that the refractive indices are correctly matched.
9. Objective lenses with higher magnifications normally have a higher numerical aperture and a shorter depth of field in the resulting image.
10. The laser light is divided by a beam splitter ( BS ) and directed by mirrors towards the two opposing objective lenses.
