In a combination of thin lenses, we use two thin lenses, a convex lens and a concave lens. Lenses formed after combinations of two or more lenses are termed compound lenses. When two lenses, such as a convex and a concave lens combine, the first lens forms an image that serves as an object for the second lens.

WebApr 7, 2024 · Convex lenses (or converging lenses) and concave lenses (or diverging lenses) are the two most common types of lenses. 1. Convex Lenses: It has the classic lentil shape as it bulges outwards in the centre of the lens (sometimes called a positive lens). The focal point of a convex lens is determined by bending rays of light passing … WebIn general, there are two types of spherical lenses. So, lenses formed by binding two spherical surfaces bulging outward are known as convex lenses, while the lenses formed by binding two spherical surfaces such that they are curved inward are known as concave lenses. This is one of the basic differences between concave and convex lenses. Webfor more than one simple lens, or a compound lens; just use it normally for the first lens, but for the second lens the image from the first lens must be used as the object for the second lens.

"WebPrisms that deviate the ray path, rotate the image, or simply displace the image from its original axis are helpful in many imaging systems. Ray deviations are usually done at angles of 45°, 60°, 90°, and 180°. This helps to condense system size or adjust the ray path without affecting the rest of the system setup.
