发明名称 LIQUID LENS WITH VARIABLE FOCAL LENGTH BY USING TRANSPARENT ELECTO-MAGNET GLASS
摘要 PURPOSE: A focus-variable fluidic lens using a transparent electromagnet glass is provided to enable electrical adjustment by a concave lens and a convex lens which can vary the light emitted from a subject. CONSTITUTION: A transparent elastic film(105) comprises a first transparent electromagnet glass(100), a second transparent electromagnet glass(101), and a transparent fluidic refraction liquid(103). The transparent fluidic refraction liquid is formed between the first transparent electromagnet glass and the second transparent electromagnet glass. A ring-shaped permanent magnet(106) is combined with the elastic film. The permanent magnet moves by the magnetic force generated between the first transparent electromagnet glass and the second transparent electromagnet glass. The shape of the elastic film is changed according to the movement of the permanent magnet.
