The double concave lens is similar to the flat concave lens. The focal length is negative, but the light incident in parallel diverges outward. The curvature radii of the two sides of the double concave lens are equal. It is generally used to increase the focal length in beam expansion light, projection and other...

Plano-concave Lenses present a concave surface and a plano surface. They have a negative focal length and are used for image reductinon or to spread light. These lenses diverge collimated incident light and form virtual images which are seen through the lens. They are often used to expand light or to increase focal...

127mm biconcave glass concave optical lens The principle of geometric drawing of biconcave lens imaging is the same as that of convex lens. The top of the object is also regarded as two straight lines: one is parallel to the main optical axis, deflects into divergent light after passing through the biconcave lens, and...

Biconcave lens is also called negative spherical lens. The middle of the lens is thin and the edge is thick. It is concave, so it is also called concave lens m. Concave lens has a divergent effect on light. The imaging law of concave lens is: when the object is a real object, it becomes an upright and reduced virtual...
