Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
As shown in Figure 1, be the eyeglass 100 that embodiment of the present invention provides, it comprises a substrate 10, an IR-cut film 20 and a waterproof membrane 30.
Described substrate 10 adopts sapphire material to make.Described sapphire belongs to corundum family mineral, and trigonal system, has hexagonal structure.Described sapphire main chemical compositions is alundum (Al2O3) (Al
2o
3), its refractive index is 1.760-1.757, this sapphire crystallization direction is a axle (11
0), c-axis (0001), m axle (10
0).The transmissivity of the Infrared that described sapphire is 825-1300nm to wavelength is greater than 85%.
Described substrate 10 has positive light coke or negative power, it comprise a thing side surface 11 and with described thing side surface 11 opposing picture side surface 12.Described thing side surface 11 and be not 0 as the curvature at least one surface in side surface 12.The light that is projected to described substrate 10 projects away through the convergence of this substrate 10 or after dispersing.
In present embodiment, described substrate 10 adopts model machine-shaping, and it comprises the following steps: melting under the high temperature of 900-1300 ℃ after sapphire is pulverized; The sapphire particle of moulding round bead shape; Adopt the mode of model processing to process sapphire particle; Shaped sapphire substrate 10.
Described IR-cut film 20 is to plate by the mode of ion gun evaporation any surface being located in described thing side surface 11 and described picture side surface 12, and it is for the Infrared part of filtering light.In present embodiment, described IR-cut film 20 platings are located at described picture side surface 12.Described IR-cut film 20 comprise from this as side surface 12 to replacing the 1st to the 54th stacking rete away from this as side surface 12 directions, wherein the material of odd number rete is titania, the material of even number rete is silicon dioxide.
In this real mode, because the 10 pairs of Infrared of described substrate that adopt sapphire to make have certain assimilation effect.Described IR-cut film 20 designs according to the assimilation effect of 10 pairs of Infrared of described substrate, to guarantee the effective filtering to the Infrared in particular range.
Described waterproof membrane 30 is to be plated and be located at another surface relative with the surface at described IR-cut film 20 places on described substrate 10 by the mode of vacuum evaporation, and it has the performance of oil rub resistance and water resistant.In present embodiment, described waterproof membrane 30 platings are located at described thing side surface 11.The main material of described waterproof membrane 30 is silicon dioxide.
In addition, in order to improve the transmission effects of 100 pairs of luminous raies of described eyeglass, between described thing side surface 11 and described waterproof membrane 30, be provided with one deck anti-reflective film 40.Described anti-reflective film 40, for reducing the reflectivity of 100 pairs of luminous raies of described eyeglass, improves transmissivity.
The hardness of the described eyeglass 100 that present embodiment provides reaches 1500-200Kg/mm
2, yield strength reaches 300-400MPa, compressive strength and reaches 2GPa, temperature range for-40-2000 ℃, and have the character such as anti-high voltage, anti-high frequency and chemical resistance.The reflectivity of 100 pairs of Infrared of described eyeglass reaches more than 99%, to the transmissivity of luminous ray, is 90%-99.5%.
