Plano concave lens




Plano-concave lenses are thicker at the edge than in the center and flat on another surface. Plano concave lens (PCV) has negative focal length. So the lenses are used to bend parallel input rays so they can diverge from one another making them useful for beam expansion and image reduction application. We offer plano concave lenses with anti-reflection coating, which markedly improves the transmission efficiency. AR coated plano concave lenses are widely used in a lot of optical imaging systems. Please send us your requirement, we will make as per specifications or drawings.
