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 series achromatic doublet cemented focusing lens telescope true sapphire ball lens 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

Optical glass BK7 50mm 60mm Protective dome lens for camera photography • Domes make it better - Domes help correct aberrations that occur when light travels thru water as opposed to air. Domes can deliver better results compared to flat ports, and also make it easier or possible some results that flat ports would not capture. • Size matters - Bigger domes are better than smaller domes, for a number of reasons. The tradeoffs are; heavier, bulkier, pricier than smaller domes.

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

Factory Direct Sales 2-250mm High Hardness Plano-Concave Lens for Optical Cylindrical lenses are designed to focus light into a straight line, rather than to a single point. As the name suggests, the lens surface has a cylindrical shape rather than the usual spherical which allows for one dimensional shaping of light along a line. Cylindrical lenses are typically either plano-concave or plano-convex, designed to expand and focus light respectively, and can be supplied in
