Title: GAS LENS
Abstract:
A gas lens comprising a sealable cavity (110) and optical gas (120). The cavity (110) has a transparent cavity wall (111, 112) for the incidence and emission of light (LL); the optical gas (120) is filled into the cavity (110); and the refractive index of the optical gas (120) is larger than the refraction index of air under the same physical conditions. The gas lens can realise continuous changes in the refraction index and reduce the weight of the lens.
