Luneberg lens is a spherical lens which its permittivity varies with normalized radial coordinates. It is fabricated by using different homogeneous dielectric centrically layered media. The lens can focus a parallel beam of rays from any direction exactly at a point on the surface. If it is made by adding a reflecting surface "metallic cap", it is called Luneberg lens reflector. It can reflect incident wave into plane wave in incoming direction. It is usually applied in antenna, radar reflector,satellite-based, and mobile-communucation.

龙伯球透镜为一种介电系数与半径成一固定比例的球形透镜，大部分是由数层不同介电系数介电质组合而成，而其主要特性能够把入射波聚焦到球表面一点，假使在透镜表面处镀上一圆锥角金属层即为龙伯球透镜反射器，能把入射波依平面波的型态反射回原入射端，通常用於天线、雷达、卫星通讯、军事等方面。

According to range of the focal distance, dropping UV glue which is crystalline and unexpensive into lens cavity with UV rays, and then forms as soon as solidifies the convex lens. Combining UV curing glue convex lens and variable focus lens, the focal distance range achieves the 8.3~24.5 mm low focal distance effect.
