Laser Cutting Creative Design Drawing | Sunglasses1

  Sunglasses can block uncomfortable strong light and protect the eyes from itultravioletThe harm caused. All of this is attributed to metal powder filtering devices, which can filter light when it enters"choice"Colored glasses can selectively absorb some of the wavelengths that make up sunlight because they use very fine metal powder(Iron, copper, nickel, etc)In fact, when light shines on the lens, based on the so-called"destructive interference"During the process, the light was reduced. That is to say, when certain wavelengths of light(This refers to ultraviolet radiationa, UV raysbSometimes there is also infrared radiation)When passing through the lens, they will cancel each other out on the inside of the lens, facing the direction of the eye. The mutual overlap of light waves is not an accidental phenomenon:The combination of the peak of a wave and the trough of a nearby wave results in mutual cancellation. The destructive interference phenomenon depends on the refractive index of the lens(The degree to which light deviates when passing through different substances in the air)It also depends on the thickness of the lens. Generally speaking, the thickness of the lens does not change much, while the thickness of the lensRefractive indexIt varies depending on the differences in chemical composition. Moreover, sunglasses should not come into direct contact with the sun. Quickly use a laser cutting machine to make a pair of sunglasses.

Kind reminder: The design drawings must be modified according to the actual type and size of materials used before use.
