    Double-Concave (DCV) Lenses have two inward curved surfaces and a negative focal length. They are used for image reduction and to spread light. Double concave lens is similar to 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 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 returns the refracted light to the main...

    Altechna wedge prism, which diverts light to the thicker part. By selecting the appropriate wedge, it is easy to create beam deviations without affecting other beam parameters. If two wedges are used close to the inclined surface, a continuous change in beam deviation can be produced by reversing the wedges. It turns...

    The variant of pentaprism is roof pentaprism, which is usually used in monocular camera. In this case, because the image projected on the fuselage will rotate 180 ° after the lens is focused, the light beam reflected from the plane mirror to the pentaprism after the focus also needs to change the left-right...

    Optical Prisms are used to redirect light at a designated angle, and its design determines how light interact with it. When light enters an Optical Prism, it either reflects off an individual surface or several surfaces before exiting, or is refracted as it travels through the substrate. Bena offers various...
