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...

A biconcave lens will radiate light with a negative focal length, which is composed of two concave surfaces with equal curvature. It is often used for beam expansion, projection and focal length expansion of the lens. Hengpu optics provides double concave lenses without coating and with antireflection coating....

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...

k9 biconcave lens glass optical lens 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 double concave lens are equal. It is generally used for beam expansion and projection.

The image formed by biconcave lens is always smaller than the vertical virtual image of the object. Biconcave lens is mainly used to correct myopia. Myopia is mainly due to the deformation of the lens, resulting in the premature collection of light in front of the retina. The biconcave lens plays the role of divergent...

The flat concave decoy mirror is a negative lens with a negative focal length, and the parallel beam will diverge after incident on the flat concave decoy mirror. The outgoing light cannot converge into a point, but seems to diverge from a virtual image point in the object space. When the absolute conjugate ratio is...

A flat concave lens emits light with a negative focal length, one of which is a plane and the other is a concave. It is often used for beam expansion, projection and focal length expansion of optical system. United optics provides flat and concave lenses without coating and antireflection coating. Antireflective film...

A flat concave lens is a lens that radiates parallel light outward. The focal length of flat concave static lens is negative, and the spherical aberration is also negative. It can be used to correct the phase difference, spherical aberration, coma and distortion of other lenses. Similar to flat convex mirror, one side...
