Difference Between Convex and Concave Lens
Convex lens
- A convex lens is thicker at its center and thinner at its edges, bulging outward like the exterior of a sphere.
- It is also known as a converging lens because it focuses parallel rays of light that pass through it.
- A convex lens converges parallel rays of light to a focal point on the opposite side of the lens from the light source.
- It can form real and inverted images when objects are placed beyond its focal point, and it can create virtual and upright images when objects are placed between the lens and its focal point.
- Convex lenses are commonly used in magnifying glasses, cameras, telescopes, and binoculars to focus and magnify distant objects.
- They are also used in eyeglasses to correct farsightedness (hyperopia) and presbyopia.
Concave lens
- A concave lens is thinner at its center and thicker at its edges, curving inward to create a hollow or dented appearance.
- It is known as a diverging lens because it spreads out parallel rays of light that pass through it.
- A concave lens causes parallel rays of light to diverge as if they originated from a virtual focal point on the same side as the light source.
- It can only produce virtual and diminished images when objects are placed on the same side as the virtual focal point.
- Concave lenses are used in eyeglasses to correct nearsightedness (myopia) and in certain scientific instruments and devices to spread out light or correct optical aberrations.
Difference between Concave and Convex Lens
Convex Lenses and Concave Lenses are the types of spherical lenses, which are optical devices that are transparent in nature. There are several differences between Convex and Concave Lenses which we will cover in this article in detail such as their distinct characteristics and uses.
Knowing the difference between Convex and Concave Lenses is critical in grasping their function in different optical systems such as binoculars, optical microscopes, telescopes, etc.
This article explores the difference between convex and concave lens in detail including their definition and key characteristics as well.
