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,

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

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

Optical Glass Lens Convex Cylindrical Lens Led Glass Lens Normally the substrates can be K9 glass or fused silica glass.And reflective coating on the concave surface.The plano surface is just fine grinding. This is the BBR reflective coating on the concave surface. Also we can make the metal coating such as Aluminium coating ,silver coating or gold coating on the concave surface. Specification Range of diameter Dia.0.7mm-Dia.400mm Range of curve radius R1.5-R etc Tolerance

High quality Square Fresnel Lens Cylindrical Optical Glass Convex Lens Plano-concave cylindrical lenses function similarly to plano-concave spherical lenses, but plano-concave cylindrical lenses only work on one axis. These cylindrical lenses are used in applications where the point source needs to be shaped in a one-dimensional direction. A typical application is to convert a collimated laser beam into a linear beam using a single cylindrical lens. A pair of cylindrical

Custom Size Glass Optical Half Long Plano-convex Cylindrical Lens For Laser Cylinder Lenses are similar to Plano-Convex lenses in profile, but include a portion of a cylinder instead of a sphere. These lenses focus light in one dimension and can transform a point of light into a line. Cylinder Lenses are available in circular and rectangular versions, along with multiple coating options. Cylinder lenses are ideal for line projection in machine vision applications or guidance

Customized optical glass telescope glued doublet fused silica achromatic cemented Lens Achromatic Lens is an achromatic consists of a positive low-index Crown Glass lens element cemented to a negative high-index Flint Glass lens element. 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

50 mm BK7 optical cemented high precision achromatic doublet fused silica laser protection plano-convex lenses 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

Optical telescope doublet achromatic lens double ball glass objective lens double sapphire welding cemented lens A cylindrical lens with convex surfaces and square volume can turn a transmitted plane wave into a cylincrical wave, or turn an original cylindrical wave into a plane wave or spherical wave, such a kind of lens can correct ocular astigmation. Cemented lens The cemented lens is also called an achromatic lens, which is formed by cementing two single lens elements.
