A flat Convex lens or plano-convex lens is an optical device that is used to focus light into a single point. The “Plano” portion of the lens refers to one side being flat (a plane) and the “convex” portion refers to the other portion of the lens being bowed outward. A plano-concave lens means it is bowed inward or is caved in. Just as the name sounds, the flat Convex lens has two sides the flat and the curved surfaces that work together. The curved surface of this lens is the positive surface and it gives a positive focal length which means that the focal point or the point where light converges is on the opposite side of the lens as the position of the object in view and this makes the image to be inverted and flipped. The surface of the flat Convex lens could be coated with anti-reflective or AR coatings to enhance the focusing properties of the plano-convex lens. Stray light bouncing around and reflecting off the lens can weaken the strength of the beam that you are trying to focus on in the first place. Due to the positive nature of the flat Convex lens, it can be used to focus, collect and collimate light at a particular point. The asymmetry of these lenses minimizes spherical aberration in situations where the object and image are located at unequal distances from the lens. Plano-convex lens has either two surfaces with positive spherical contours. The asymmetry caused by the one side of the mirror the flat surface, one side convex lens minimizes spherical aberration in certain applications where the object and image are at unequal distances. Some flat convex lens factoryare there to provide you the best quality of lens like at Alpine Research Optics. Regardless of design, the thickness at the edge of the lens is always less than the thickness at the center. The lens is used to focus light to a pre-defined point based on the amount of curvature of their surfaces. This lens is used commonly where the object being imaged is far away from the lens, and this is called infinite conjugate which can be explained in the circumstance is focusing light from a distant object such as a star. This lens is used in some research optical company.
Application Of Flat Convex Lens
- The principle of flat Convex lens is used in telescopes
- It is also used in binocular lens
- Our common light microscope uses the same principle
- Flat Convex lens is used in the treatment of long-sightedness
- The principle that is used in Flat-convex lenses are often used for cutting steel or other thick materials via laser just as windows optical
Features Of Flat Convex Lens
- Plano-convex lenses are positive focal length elements that have one spherical surface and one flat surface
- They are designed for infinite conjugate
- These optic lenses are ideal for all-purpose focusing elements
- The positive focal length elements of the lens have one curvature surface and one flat surface
- The curved surface has a focusing effect on the rays of light but the flat surface lacks this feature
- The quality of the image is determined based on its orientation and two positive focal lengths
- To obtain an image with maximum sharpness the curved side of the lens should be facing toward the object and not the flat side
- The image formed is inverted as compared to the object, the image formed is called a real image
- The image formed is upright as compared to the object, the image formed is called a virtual image
- The virtual age can not be captured on screen
