Concave vs Convex Lens β Tabular Difference
There are various key differences between the Convex Lens and Concave Lens, which are listed in the following table:
Characteristic | Convex Lens | Concave Lens |
---|---|---|
Lens Shape | Thicker at the center, bulging outward | Thinner at the center, curving inward |
Focusing | Converging lens, brings parallel rays to a focus | Diverging lens, causes parallel rays to spread out |
Principal Focus | Real, located on the side of incoming light | Virtual, located on the same side as incoming light |
Image Formation | Can form real or virtual images | Always forms virtual, upright, and diminished images. |
Magnification | Can have positive or negative magnification | Always has a negative magnification. |
Lens Thickness | Thicker at the center | Thicker at the edges. |
Lens Curvature | Curves Outward | Curves inward. |
Focal Length | Positive focal length | Negative focal length |
Lens Equation | 1/f = 1/v + 1/u | 1/f = 1/v β 1/u |
Image Size | Can be larger, smaller, or same size as object | Always smaller than object. |
Applications | Cameras, projectors, magnifying glasses | Corrective eyeglasses, optical experiments |
Lens Aberrations | More prone to chromatic aberration | Less prone to chromatic aberration. |
Field of View | Widens field of view for magnification | Narrows field of view for correction. |
Lens Types | Biconvex, Plano Convex | Biconcave, Plano Concave |
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.
