As the name suggests, plano concave lenses are optical lenses with two types of surfaces: concave and flat. These are useful devices that can be used for increasing the focal length of an optical system. They are available as plano concave lenses and plano concave cylindrical lenses, having a range of diameter and focal length. Learn lens specification and their applications to buy the best product for your needs.
A plano concave lens makes the best choice when an object is at absolute conjugate ratios. It effectively curves parallel input rays to disunite from one another on the other side of the lens. This is why the lens has a negative focal length. In other words, the lens expands light beams or increases optical systems’ focal lengths. Plano concave lenses are thicker at the edge than the center. The other side of the device is flat.
On the other hand, plano convex lenses are positive lenses that help focus light to form an image. The surface of these devices bulges outwards in the center to offer a lentil-like shape.
Applications of Plano Concave Lenses
Today, a wide variety of plano concave lenses are made to optimize them for various purposes. For example, they are available in different shapes and diameters. Apart from that, there can be coated and uncoated lenses. Depending on their types, they can be used for different purposes.
Applications of these lenses include optimizing them for the ultraviolet and infrared spectrum. Apart from that, they can be customized for unique applications.
How to Buy the Right Lenses
The lens world is growing bigger with each passing day. Whether you require plano concave or convex concave lenses, you need to consider multiple things. They include the type of lens, diameter, focal length, and their applications. Remember, convex concave lenses cannot produce the output you expect from a plano concave lens.
Apart from that, the diameter and focal length of a lens play a huge role in generating outcomes. While buying a lens, ensure to buy it from a reliable supplier. The service provider must have a range of lenses to match them with your requirements. Before ordering one, don’t forget to check their material, design wavelength, center thickness tolerance, surface figure, surface quality, and price.
