No - by definition. You can have a plano-convex (or -concave) lens (one side flat). Actually a purely plano "lens" would be merely a glass disc.

What did the microscope Zacharias Janseen invent look like?
It was a tube with lenses at each end. The magnification ranged from 3X to 9X depending on the size. The eyepiece lens was bi-convex and the far end lens was plano-convex.
Does a microscope use a concave lens or a convex lens?
Today's microscopes use convex lenses.
What is the antonym for the word concave lens?
convex lens
Is an outward curving lens?
The outward curving of the lens is said to be a convex lens.
Which mirror is used in solar cooker Concave or convex mirror or concave lens or convex lens?
convex mirror is not used in solar cooker since it form image inside the polished surface
Howdoes plano convex lens make fringes circular?
A lens that only has one flat surface is called a plano convex lens. The plano convex lens makes fringes circular because the air film is symmetrical.
Does fresnel lens is a convex lens?
yes...it is a plano-convex lens....wid grooves cut in it on convex side...it is very very thin as compared to a simple convex 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 lens is a converging lens double-convex spherical-convex plano-concave or convexo-concave lens?
A converging lens is also known as a magnifying lens. The shape of the lens is a double convex shape.
Name two lenses used in stage lighting instruments?
There are a variety of lenses used in theaterical or stage lighting. Here is a short list and their uses: Plano-Convex- This lens is used in standard Ellipsoidal Spotlights. One side is flat(plano) and the other is Convex. Convex-convex- This lens is also used in conjunction with Plano-Convex. This, however, has both sides of the lens as convex. Fresnel lens- Used in fresnels to disperse the light Par- These lenses are intergrated into the filament, envelope, and base of the lamp. These are bubble type lenses.
Which lens is a converging lens a double-convex lens or a spherical-convex lens or a plano-concave lens or a convexo-concave lens?
Your are mixing properties. Converging lens is always thicker in the centre and thinner at the edges. The other cathegory is the geometry of shape of the surfaces of the lens. Convex means that the shape is similar to the outer surbace of a sphere, concave means that the shape is similar to the iner surface of a sphere (or: convex = lower side of a spoon as we use it for sampling a soup; concave: upper (inner) shape of the spoon). A double convex lens is always a converging lens. A plano-concave lens is always a diverging (not converging) lens. A convexo-concave lens is the most usual shape of a lense used in spectacles. It can be either converging or diverging, depending on the radii of the surfaces.

What is a lens that is thicker in the middle than at the edges?
a convex lens
A magnifying glass is an example of what lens?
Plano Convexif its for penn foster it's a CONVERGING lens.just took the test.
What kind of lens does a projector use?
projector have concave or convex
Do flashlights have convex or concave lens?
convex lens
What part of a convex lens is thicker?
The convex lens are the converging lens. The periphery of the convex lens is thinner & the center part is thicker. In other words, the convex lens are bulging at the center & thinner at the periphery.
