Description
Technical field
The invention belongs to eyeglass manufacturing technology field is and in particular to the system of a kind of high index of refraction, high Abbe number resin lens
Make technique.
Background technology
According to the applicant understood, refractive index is the ratio of light speed in a vacuum and light speed within this material.Material
Refractive index higher, make incident illumination occur refraction ability stronger.Refractive index is higher, and the thickness of eyeglass is thinner, i.e. center of lens
Thickness is identical, identical number of degrees same material, and the low lens edge of the high specific refractivity of refractive index is thinner.Common eyes on market
Eyeglass is broadly divided into sheet glass, resin sheet, universe piece etc. according to material.Because anti-impact force is strong, non-friable, resin lens are more next
More favored by people.With the development in glasses market, the cognition continuous improvement to resin lens for the consumer, simultaneously also to product
The performance of product and function is put forward higher requirement so that the sales volume of low-refraction eyeglass progressively glides, high index of refraction simultaneously possesses
The eyeglass of premium properties is popular with consumers again.On domestic market independent development study high index of refraction eyeglass producer almost
No, high index of refraction product almost leans on import entirely, not only expensive, and its quality and performance can not meet wanting of consumer
Ask.Therefore, develop a kind of resin lens of high index of refraction, be very necessary.In general, the refractive index of material is higher,
Dispersion is more severe, and that is, Abbe number is lower.Abbe number is used to weigh the light degree of dispersion of medium, due to same transparent medium pair
There is the difference of refractive index in the light of different wave length, and what white light was made up of the white light of different wave length, therefore transparency material
When reflecting white light, this phenomenon of dispersion can occur.Abbe number is exactly the inverse proportion representing transparency material dispersive power
Index, the less dispersion phenomenon of numerical value is more severe, and the Abbe number of optical lens material is typically between 30 to 60.At present, on market
High folding product predominantly 1.670,1.740, its Abbe number generally between 32 to 33, and this product depend on into
Mouthful, such as Korea S and Japan, the unit price leading to product because of product import costly, simultaneously because the Abbe number of product is low, color
Dissipate severity, the selection of consumer can be affected.
