Today's microscopes use convex lenses.
Concave
They use convex lenses because they need to focus the light IN to the eye. Convex focuses in while concave spreads the light out. So, they use convex lenses.
A concave lens is thinner at the centre. People who are short sighted often use a concave lens to help them see better.
ocular lens
you use two convex lenses.
projector have concave or convex
You would use a convex lens.
Convex Lens
Concave lenses are used in the eyepieces of microscopes. However, they are not used alone on the eyepiece, but are joined in a concave-convex combination to prevent internal reflections.
Magnifying glasses use convex lenses
Both concave and convex lenses are used in glasses; A microscope, like a reflecting telescope, uses a concave mirror, a plane mirror, and a convex lens; A refracting telescope uses two convex lenses to magnify images in the sky; binoculars use concave lenses to improve detail.
Concave
No, a movie projector uses a convex 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.
i guess it doesnt really matter. my magnifying glass is a convex lens so yaaaa. well that's all i got cuz this website don't even no what a concave or convex lens is.
The convex of the microscope lens proved to be unhelpful as I still could not find Jupiter.
