A piece of glass, or other transparent substance, ground with two opposite regular surfaces, either both curved, or one curved and the other plane, and commonly used, either singly or combined, in optical instruments, for changing the direction of rays of light, and thus magnifying objects, or otherwise modifying vision. In practice, the curved surfaces are usually spherical, though rarely cylindrical, or of some other figure.

Are plano lens convex?
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.

Is the word lens plural?

What part of a microscope regulates resolution and definition of the specimen?
The objective lens of a microscope is responsible for regulating resolution and definition of the specimen. The quality of the lens and its magnification power play a key role in detailing the specimen being observed.
What is the definition for the word cataract?
Cataracts are where the lens of the eye becomes clouded and thus causes reduced vision. This most commonly affects elderly people. It can be treated with surgery where the lens is replaced by a synthetic lens. A cataract is also a waterfall or series of rapids in a river.

What are the features and benefits of the 2.2x high definition telephoto lens?
The 2.2x high definition telephoto lens offers increased magnification for capturing distant subjects with clarity and detail. This lens enhances the zoom capabilities of your camera, allowing you to get closer to the action without compromising image quality. The benefits include sharper images, improved focus on distant subjects, and the ability to capture more detailed shots from a distance.
What is the definition of a high power objective lens 40x?
A high power objective lens 40x refers to a microscope lens that magnifies the specimen 40 times its actual size when viewed through the microscope. This lens is used for detailed observation of fine structures and requires careful focusing due to its high magnification level.
