50.8mm glass optical concave lens
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...
50.8mm bi concave optical lens glass lens
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....
50.8mm glass biconcave glass optical lens
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...
50.8mm 2" bioconcave optical lens glass lens
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....

glass bi concave optical glass 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.
bk7 bi xoncave glass optical lens
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...
k9 bi concave lens glass optical
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....
optical lens 12.7mm bi concave lens
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....
k9 25.4mm bi concave lens optical lens glass
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....
127mm bi concave glass optical glass lens
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...
k9 optical biconcave glass lens 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 returns the refracted light to the main...
