What is Plano Concave (PCV) Lenses?
A plano-concave lens is an optical lens with one concave surface and one flat surface. It has a negative focal length and is commonly used in light projection, beam expansion, or to increase the focal length of an optical system.

What is the application of Plano Concave (PCV) Lenses?
1. Security surveillance: plano concave lenses are commonly used in security surveillance cameras to help capture clear images.
2. Infrared gas analyser: in an infrared gas analyser, a plano concave lens is used to focus infrared light to help detect and analyse the gas composition.
3. Night vision products: plano concave lenses play a role in night vision equipment to enhance night vision.
4. Infrared detectors: plano concave lenses are used in infrared detectors to help capture and focus infrared radiation for thermal imaging and other infrared applications.
5. Infrared receiver: in an infrared receiver, a plano concave lens is used to receive infrared signals and is commonly used in devices such as remote controls.
6. Infrared sensing: plano concave lenses are used in infrared sensors such as infrared sensing switches and sensors for automatic control of lighting and electrical appliances.
7. Infrared communication products: in infrared communication products, plano concave lenses are used to send and receive infrared signals to achieve short distance wireless communication.
8. Surveillance cameras: plano concave lenses are used in the lenses of surveillance cameras to help capture clear video images.

Is a plano concave lens converging or diverging?
Plano-concave lenses, characterized by one concave surface and one flat surface, diverge incoming light, spreading it out as it passes through the lens.
