Abstract
The invention relates to a first lens for a micro combined optical system. The first lens (G1) for the micro combined optical system is a biconvex lens, the diameter (R1) of the first lens is 5mm plus or minus 0.2mm, the edge thickness (TE1) is 1.57mm and the center thickness (TC1) is 2.6mm plus or minus 0.02mm. The first lens for the micro combined optical system has the advantages that the effects of miniaturization and high resolution are realized, the image distortion of a micro camera is effectively overcome, the color revivification degree is high, the images are clear and sharp and the first lens can be conveniently applied to various portable digital products.
Description
Technical field
The present invention relates to optical technical field, especially a kind of micro combined optical system the first eyeglass.
Background technology
The digital camera functionality of the digital equipment such as mobile phone, panel computer obtains and develops rapidly.Along with the raising of camera pixel, its shooting effect is also more and more close to traditional card camera even low side slr camera.
Summary of the invention
The object of the present invention is to provide a kind of micro combined optical system the first eyeglass.To meet micro-lens miniaturization, high resolving power, high performance requirement.
Technical scheme of the present invention is:
A kind of micro combined optical system the first eyeglass, described micro combined optical system is lenticular eyeglass with the first eyeglass G1, and its diameter R1 is 5 ± 0.02 millimeters, and edge thickness TE1 is 1.57 millimeters, and center thickness TC1 is 2.6 ± 0.02 millimeters.
Described micro combined optical system is 4.837646 millimeters by the radius-of-curvature of the thing side mirror face S1 of the first eyeglass G1, effective diameter ∮ 2.4, refractive index is 1.850250 ± 0.0005, and abbe number is 32.17 ± 0.5%, centering coefficient is 0.3894, and optics bias is 60 〃.
Described micro combined optical system is 9.53994 millimeters by the radius-of-curvature of the image side minute surface S2 of the first eyeglass G1, effective diameter ∮ 2.6, and refractive index is 1.850250 ± 0.0005, and abbe number is 32.17 ± 0.5%, and centering coefficient is 0.3894, and optics bias is 60 〃.
The invention has the beneficial effects as follows:
Micro combined optical system the first eyeglass of the present invention achieves miniaturization, high resolving power, and effectively overcome the image deformation of micro-lens, color rendition degree is high, and imaging clearly is sharp keen, can be applied to easily in all kinds of portable digital product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
