    Our company is recognized as one of the most preeminent Precision Plano Concave Lenses Manufacturers in India. The Plano Concave Lenses are made from various materials, which are manufactured with one concave surface and one plane surface. These lenses have negative focal lengths. These lenses diverge the collimated incident light to form virtual images which are seen through the lens. PCV Lenses are often used to expand light or to increase focal lengths in existing systems. We also offer precision grade Plano Concave Lens with tighter manufacturing tolerances.

    These lenses are thicker at the edge than in the Centre and flat on one side. The Plano–concave lenses are used to expand light beams or to increase focal lengths in optical systems.Plano–Concave lenses bend parallel input rays to diverge from one another on the output side of the lens and hence have a negative focal length. They are the best choice when object and image are at absolute conjugate ratios greater than 5:1 and less than 1:5 to reduce spherical aberration, coma and distortion.
