Typically the lens axis passes through the physical centre of the lens, because of the way they are manufactured. Ideal for high performance and high power beam expansion and aberration-balancing tasks in the visible and near-infrared, these N-BK7 plano-concave lenses reduce aberrations when used at near-infinite conjugate ratio. Choose products to compare anywhere you see 'Add to Compare' or 'Compare' options displayed. PCV Lenses are ideal for use in a range of applications or industries. Plano-concave lenses diverge a collimated beam from a virtual focus and are commonly used in Galilean-type beam expanders. Plano-Concave Lens These lenses have one flat surface and one concave surface. 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. Most lenses are spherical lenses: their two surfaces are parts of the surfaces of spheres. VIS 0° Coated Plano-Convex (PCX) Lenses. Given their negative focal length and negative spherical aberration, plano-concave lenses can be used to balance out aberrations of other lenses in the system.

Lenses may be cut or ground after manufacturing to give them a different shape or size. You can change this selection at any time, but products in your cart, saved lists, or quote may be removed if they are unavailable in the new shipping country/region. The lens axis may then not pass through the physical centre of the lens. The UV Fused Silica substrate is ideal for Ultraviolet (UV) imaging or laser applications. Edmund Optics’ anti-reflection coatings include UV-AR, MgF2, VIS 0°, VIS-NIR, NIR I, or NIR II. 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. They are offered in a wide range of focal lengths and diameters, with a large selection of optional high energy AR coatings. Edmund Optics offers the world’s largest inventory of off-the-shelf optical components, including a wide variety of Plano Concave Lenses. Login to view your complete order history. Address Book, The plano-concave lenses are used to expand light beams or to increase focal lengths in optical systems. A beam incident on a concave surface will be focused to a point outside the instrument. UV Fused Silica substrate options are available, offering additional performance in the Ultraviolet (UV) spectrum. Edmund Optics’ anti-reflection coatings include UV-AR, MgF 2, VIS 0°, VIS-NIR, NIR I, or NIR II. N-BK7 lenses are a great choice for most general purpose visible and NIR applications, featuring high homogeneity and low bubble and inclusion content. Tax Certificates. 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 have a negative focal length and are used to diverge incoming light, or to increase focal length in an existing optical system. Because the spherical aberration of the Plano-Concave lenses is negative, they can be used to balance aberrations created by other lenses. PCV Lenses should be oriented with the plano, or flat, surface towards the desired focal plane. You may also fill out the below form and we will contact you: Thank you for allowing us to help you.
