    Optical Mini Glass Bk7 Dome Lens K9 od3.98 inch Hemisphere Guide Top Camera Coating Dome Lens For Video Camera A single lens used to form an image will always show some chromatic aberration, that is variation of focal length with wavelength. Achromatic doublet lenses correct for this as they are constructed from two different glass types and designed to remove first order chromatic aberration. Generally spherical aberration is reduced at the same time. Achromatic doublets are

    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

    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
