What is Double Concave (DCV) Lenses?
Two Inward Curved Surfaces and a Negative Focal Length. Used for Image Reduction and to Spread Light.

What is the application of Double Concave (DCV) Lenses?
1. Optics experiments: in optics experiments, biconcave lenses can be used to study the focusing and diverging properties of light and the effect of lenses on the path of light.
2. Lighting systems: in some special lighting systems, biconcave lenses can be used to adjust the distribution of light so that it illuminates the target area more evenly.
3. Laser systems: in laser systems, biconcave lenses can be used to focus the laser beam, thereby increasing the power density and energy concentration of the laser.
4. Imaging system: in the imaging system, biconcave lenses can be used in conjunction with other optical elements to achieve a clear image of the object.
5. Optical communication: in the field of optical communication, biconcave lenses can be used to focus and collimate light beams to improve the efficiency and quality of optical signal transmission.
6. Medical devices: in medical devices, biconcave lenses can be used to focus lasers for surgical treatments or in imaging systems to help doctors see inside a patient's body.

What is a double concave lens in the eye?
Bi-Concave (Double-Concave) lenses have equal radius of curvature on both sides of the lens and function similarly to plano-concave lenses by causing collimated incident light to diverge.
