43mm Optical lenses protective dome ball and half ball lenses glass cover used for underwater photography Concave lenses, are a simple lens with one spherical face and one flat plano face. Because the spherical face is concave the lens has a negative focal length, allowing the part to increase the divergence of convergent light. Concave lenses can be used to balance out the spherical aberrations caused by other lenses. This makes concave lenses very useful for controlling

Dome Infrared Fresnel Lens Led Module 80mm Aacrylic pc Big Underwater Camera Lens For PIR Motion Module Fresnel lenses consist of a flat surface with interspaced, concentric steps whereby each step corresponds to the surface of a conventional lens. Each step thereby acts as a refractive surface, much like a prism. This gives the Fresnel lens a common focal length equivalent to a traditional lens, but with a fraction of the thickness. Additionally, because the lens is so thin

Wholesale Optical glass plano convex lens/flat convex glass lens Condenser lenses are used for concentrating light into a beam. Condenser lenses are typically used in enlargers, projectors and illumination lighting systems. This range of large condenser lenses have been optically polished and of high quality at very reasonable prices. Our stock range of high quality planoconvex condenser lenses are available direct from this page with focal lengths between 250mm to 500mm and
