Function of Objective lens?

By controlling the magnification and resolution of the image, the objective lens plays a crucial role in determining the quality and clarity of the observed sample.


Technique that produces a 3-D photographic image without a lens?

Holography is a technique that produces a 3-D photographic image without the use of a lens. This process involves the use of laser light to create an interference pattern on a photosensitive surface, resulting in the visualization of a 3-D image when viewed under appropriate lighting conditions.


How to determine the focal length of group of lenses?

Measure the distance from the center of the lens to the area where it 1.)Produces a clear image of very distant objects, 2.) The Sun (Be careful!), 3.) The Moon, 4.) A bright star or planet. The source needs to be at or near infinity. If you use a light source that is close to the lens, your results will not be accurate. Of course, if you know the F ratio, you have it! An F/2 lens will be twice the diameter of the lens. An F/10 will be ten times, etc.
