bk7 aspherical optical lens

Customized Diameter BK-7 Optical Glass Lens And Prism For Instruments Device Tools the equilateral triangular prism can appear seven color light like rainbow when you rotates the prism under the sunshine. Light goes into one of sides from the prism,then goes out from another side. the light that has gone out will be deflection refract toward the third side,deflection refraction angle , the refraction index of the prism and top angle is concered with the angle of incidence

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
