Description

Water lens

[Technical Field]

Field of the Invention This invention relates to the field of lenses, and more particularly to the use of liquids such as water as lenses for amplifying, focusing, and imaging the subject.

【technical background】

As a device with functions of amplification, focusing, imaging, etc., the lens has a wide range of applications in daily life, industrial production, aerospace, defense and military.

At present, the development of lenses has mainly gone through two stages. In the early days, ordinary lenses were used. The general lens has high transmittance and high image quality. However, ordinary lenses have high cost, thick thickness and inconvenient use. Therefore, the French physicist Augustin Jane Fresnel invented a threaded lens, also known as a Fresnel lens, which has a smaller amount of material and a smaller weight and volume than a conventional lens. Compared with the earlier lenses, the Fresnel lens is thinner and can build a lens with a larger aperture, which is characterized by a short focal length. However, since the use of a Fresnel lens to project light reduces the imaging quality, it is generally used for imaging. Where quality requirements are less critical or where general lenses are not available.

Whether it is the first generation of ordinary lenses or the second generation of Fresnel lenses, the lens body needs to be made of the entire solid material to achieve the effect of magnification, focusing or imaging, so that the cost of raw materials is very high. Moreover, in the middle of the lens processing, the intermediate parts are easily contracted and deformed, causing unevenness between the parts. In the production process, very precise equipment and instruments are required for processing and testing, and the manufacturing cost is also very high. Moreover, the transportation, carrying and use of conventional lenses that are bulky and heavy are inconvenient.

[Summary of the Invention] The object of the present invention is to solve the problems existing in the prior art, and to provide a water lens, which not only can greatly reduce raw materials and production costs, simplify the production process, but also is convenient for transportation, carrying and use.

In order to achieve the above object, the present invention proposes a water lens comprising a transparent casing, wherein the casing is provided with a liquid injection chamber, and the casing is provided with a liquid injection port, and the liquid injection chamber can inject a liquid.

Preferably, the liquid injection port and the liquid discharge port are provided with an openable and closable sealing cover, and the structure is more reasonable and convenient to use.

Preferably, the liquid inlet is provided with an openable and closable sealing cover, which is more convenient to use.

Preferably, the casing comprises two parts, an upper casing and a lower casing, and the upper casing and the lower casing are welded or bonded to each other, and the structure is simple and the cost is low.

Preferably, the housing is an integrally formed structure, and the overall sealing performance is better.

Preferably, the casing is made of a hard plastic material or glass, such as a PC material or a PMMA material or glass, and a hard material is used to ensure sufficient strength.

Preferably, the housing is made of a soft plastic material, such as a PE material or a PP material, and is made of a soft material, which is convenient to carry and use.

Preferably, the liquid added into the liquid injection chamber of the casing is water, and water is used as a main body for amplification, focusing, and imaging, and the cost is very low, and the resources are abundant.

Preferably, the liquid added to the liquid injection chamber of the casing further comprises at least one of an antifreeze, a penetration enhancer, and a stabilizer. Antifreeze prevents the use of icing in the case of very low temperatures, the penetration enhancer increases the light transmission, and the stabilizer improves stability.

Preferably, the liquid added in the liquid injection chamber of the casing further comprises a solvent capable of absorbing infrared light, and the solution is mainly used in the field of solar energy, because the infrared light in the sunlight has a heating effect on the object, which easily causes the surface of the object to heat up. And the main use of solar energy is visible light, therefore, the absorption of red The external light solvent can directly absorb the infrared light in the lens, which reduces the heating radiation to the solar cell, avoids the high temperature and affects the performance, and is simpler than the conventional structure of using a composite lens to absorb infrared light. A lot, and the cost is reduced, and the effect is good.

Advantageous Effects of the Invention: The present invention processes a casing, and after injecting a liquid such as water into the casing, uses water as a main body for amplification, focusing, and imaging, which is a brand new lens structure, completely different from ordinary lenses and phenanthrene. The raw material and processing cost of the Ner lens is only about 10%~20% of the traditional two types of lenses, and the water transmittance can reach 99%, which is higher than the traditional two types of lenses, and the use is very long. After the time water is polluted, it can be re-injected with new pure water and then continue to be used, and the service life is greatly extended. The invention of the lens will be revolutionary to the development of the lens industry, its very low cost and good performance make up for the shortcomings of the traditional two types of lenses, at the same time, the production requirements of the invention are very low, the process is simple, and the water The lens is easy to transport, carry and use.
