度に使用できるレンズ。A lens (ionic crystal material, light transmission range 0.11 to 70μ) built into the vacuum layer is a material with good transmittance for light (ultraviolet rays, visible light, infrared rays), and an ionic crystal material is used in the lens, for example, Uses quartz glass (light transmission range 0.155 to 4.5 μ) to prevent heat conduction, prevent changes in density, refractive index, focal length, focal point, etc. due to temperature changes, and is built in a vacuum layer. A lens that can be used at low and high temperatures by keeping the temperature of the lens at a constant temperature, making the density constant, constantly stable refractive index, always stable focal length, and always stable focus.
