Description

Anti infrared ray lens

Technical Field

The utility model relates to a lens technical field, more specifically say, it relates to an anti infrared ray lens.

Background

According to the wavelength of light, the light is divided into ultraviolet light, visible light and infrared light, and the light that people can usually feel visually is called visible light (380-. The ultraviolet ray is outside the purple light in the spectrum and is invisible light, and the wavelength of the infrared ray is larger than that of the visible light and is also invisible light outside 780 nm. In the past, people pay attention to protection against ultraviolet rays, but are careless against infrared rays, which are heat radiation and have strong penetrating power, can directly reach the eyeground of eyes and be absorbed by the retina to cause acute eye injury, and even induce cataract after long-term irradiation. People need to protect eyes under special working environments, such as electric welding operation, high-temperature melting furnaces, scientific experiments and the like, so as to prevent the occurrence of impaired vision, eye diseases and the like.

Most base materials of the existing common anti-infrared lenses on the market are PC polycarbonate series and the like, the color of the lenses is changed only by adding toner into the base materials or achieving the anti-infrared effect only through a film coating method, the material cost is high, the added toner can only absorb infrared light in a single waveband, and most of the anti-infrared rays in the prior art can only reach the waveband of 780nm ~ 1000nm or about 1000 nm.

In view of this, the designer of the present invention has a deep idea of the above-mentioned deficiency and inconvenience, and actively studies and improves the present invention.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an anti infrared ray lens, the structural layer is simple, not only has the general anti ultraviolet anti UV's protecting effect, but the multiband absorbs the infrared ray, guarantees visible light transmissivity simultaneously, and the lens base colour keeps unchangeable, and manufacturing cost is lower, fully protects eyes.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

an anti-infrared lens, comprising: the base material layer, the IR toner layer, the strengthening layer and the anti-IR layer, the IR toner layer is fixedly arranged on the front side and the back side of the base material layer, the strengthening layer is fixedly arranged on the surface, far away from the base material layer, of the IR toner layer, and the anti-IR layer is fixedly arranged on the surface, far away from the IR toner layer, of the strengthening layer.

The thickness of the strengthening layer is 3-8 μm.

The thickness of the substrate layer is 1.5-3 mm.

The thickness of the IR resistant layer is 3-8 μm.

The substrate layer is made of a PC material with the refractive index of 1.586 or a PA material with the refractive index of 1.52.

Adopt above-mentioned technical scheme, the utility model discloses an establish one deck IR toner layer in the middle of substrate layer and strengthening layer, set up the anti IR layer of one deck again on strengthening layer surface to anti infrared effect is better, can the multiband absorption infrared light, the infrared absorptivity of 780 ~ 2000nm wave band can reach more than 90%, visible light perspective can be for 15-85% within range, and lens film colour does not change, the field of vision is clear pleasing to the eye, fully protect eyes, and whole lens base colour keeps unchangeable, and production cost is lower, has very high market spreading value.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1, the present invention discloses an anti-infrared lens, comprising: the substrate layer 1 can be made of a PC (polycarbonate) material with a refractive index of 1.586 or a PA (nylon, polyamide fiber) material with a refractive index of 1.52, so that the substrate layer 1 is not limited to a PC polycarbonate series, the substrate layer 1 can also be made of a PA (nylon, polyamide fiber) material with a refractive index of 1.52, and has excellent optical performance, wherein the IR resistance layer 4 can more effectively filter infrared rays, 901% of infrared rays can be filtered by utilizing two different processes of the IR toner layer 2 and the IR resistance layer 4, and if only a simple IR toner layer or the IR resistance layer can only reach 45% -50%, even if the amount of IR toner and the amount of the reinforcing agent are increased more than 90%.

Therefore, the utility model discloses an establish one deck IR toner layer 2 in the middle of substrate layer 1 and strengthening layer 3, set up one deck anti IR layer 4 at strengthening layer 3 surface again, possess dual anti infrared ray function, thereby anti infrared ray's effect is better, can the multiband absorption infrared light, the infrared absorption rate of 780 ~ 2000nm wave band can reach more than 90%, visible light perspective can be for 15-85% within range, and lens film colour does not change, the field of vision is clear pleasing to the eye, fully protect eyes, and whole lens base colour keeps unchangeable, manufacturing cost is lower, very high market spreading value has, just the utility model discloses the common anti UV's of preventing ultraviolet protective effect.

Wherein, the thickness of the strengthening layer 3 can be 3-8 μm, the thickness of the substrate layer 1 can be 1.5-3mm, and the thickness of the IR-resistant layer 4 can be 3-8 μm.

Furthermore, the utility model discloses a following step preparation forms: before the substrate layer 1 is ejected, 7-9g/1Kg of IR toner is added into the raw materials, the raw materials are ejected after being dried, so that IR toner layers 2 are fixedly arranged on the front and back surfaces of the substrate layer, after the substrate layer 1 is ejected, reinforcing liquid is hardened, surface drying is carried out, a reinforcing layer 3 is fixedly arranged on the surface, away from the substrate layer 1, of the IR toner layer 2, then an anti-IR layer 4 is fixedly arranged on the surface, away from the IR toner layer, of the reinforcing layer 3 in a dip-coating mode and in a matched drying mode, wherein the anti-IR layer 4 is formed by adding 5-10g of IR toner in a range of 1 liter in a solvent of methanol of the reinforcing liquid and dissolving.
