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

High Temp Round Optical Glass Double Achromatic Lens Cemented Lenses Specification Cemented lens: The cemented lens is also called an achromatic lens, which is formed by cementing two single lens elements. The performance of multi-color (white light) imaging is much higher than that of a single lens. The achromatic lens consists of two lenses of different materials glued together to correct the dispersion of the glass. Eliminating the problem of chromatic aberration,

High Resolution cctv lens Focusafe 5MP 12mm Low distortion M12 Board Lens for Scan Camera The S-mount lens connection is a standard connection for small mini lenses that can be installed directly on the circuit board of the sensor of industrial cameras with the help of a lens holder. Because of this, the lenses are often referred to as board lenses. Typically, a male M12 metric thread with a pitch of 0.5mm is used on the lens. The supported sensor formats range from the

Brief Introduction of Fresnel lens: Fresnel lens, succession of concentric rings, each consisting of an element of a simple lens, assembled in proper relationship on a flat surface to provide a short focal length. The Fresnel lens is used particularly in lighthouses and searchlights to concentrate the light into a relatively narrow beam. Fresnel lens Parameters: Fresnel lenses consist of a series of concentric grooves etched into plastic. Their thin, lightweight construction,
