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 lengths in existing systems.

What is the use of a Fused Silica Plano Concave Lens?
Fused Silica Plano Concave Lenses serve for image reduction or light - spreading purposes. They diverge collimated light, making them ideal for expanding light beams in optical systems. Moreover, they can increase focal lengths in existing setups, aiding in optimizing optical paths. Valued for fused silica’s excellent optical properties, these lenses are widely applied in fields requiring precise light control, such as laser technologies and optical instruments, to achieve specific imaging or light - manipulation goals.
