Lenses are combined to control or manipulate light rays to achieve specific optical properties, such as focusing, magnification, or aberration correction. By combining different lenses with complementary properties, it allows for the creation of more complex optical systems with enhanced functionality and performance.

What do you mean by an equivalent lens and equivalent focal length?
An equivalent lens refers to a lens used on a different format camera that produces a similar field of view as a given lens on a specific format camera. Equivalent focal length is the focal length of the equivalent lens on the different format camera that provides a similar angle of view as the original lens on the specific format camera.
What is the pole of a lens?
The pole of a lens is the midpoint of the lens' geometric axis. It is where the principal axis intersects the lens.
What is Another name of convex and concave lens?
A convex lens is also known as a converging lens, while a concave lens is also known as a diverging lens.
What happens when you combine more than one lens?
When you combine more than one lens, the overall effect is determined by the properties of each individual lens and how they interact with each other. Depending on their arrangement, lenses can either magnify or reduce the size of the image, change the focal length, or correct for certain optical defects such as aberrations. The combined system forms a new optical system with its own unique set of characteristics.
What does a 58mm lens mean?
A 58mm lens refers to the diameter of the lens barrel at the front of the lens. This measurement is important for selecting compatible lens filters and accessories. It does not directly relate to the focal length or zoom capability of the lens.
How would you combine lenses if you wanted to magnify an object 100x?
To achieve a 100x magnification, you can combine two lenses in a compound microscope configuration. The first lens, known as the objective lens, magnifies the object by around 10x. The second lens, the eyepiece, further magnifies the image produced by the objective lens by another 10x, resulting in a total magnification of 100x.
What do you mean by an equivalent lens and equivalent focal length?
An equivalent lens refers to a lens used on a different format camera that produces a similar field of view as a given lens on a specific format camera. Equivalent focal length is the focal length of the equivalent lens on the different format camera that provides a similar angle of view as the original lens on the specific format camera.
What is the name given to the lens in a human eye?
It is lens. The lens consists of the lens capsule, the lens epithelium, and the lens fibres.
What is ocular lens and objective lens?
The ocular is the upper lens and objective is the lower lens

What is a crystalline lens?
A crystalline lens is the lens in the human eye.
What is the pole of a lens?
The pole of a lens is the midpoint of the lens' geometric axis. It is where the principal axis intersects the lens.
Which of the following lenses is a converging lens A double-convex lens B spherical-convex lens C plano-concave lens D convexo-concave lens?
Double-convex lens
What is a lens cap?
= A lens cap is a cover to a lens on a camera or camcorder.=
What is the upper lens?
The upper lens is called the ocular lens or the eyepiece.
What part of A camera lets in light?
The Shutter.
