Abstract
The invention relates to a first lens for a miniature combined light optical instrument containing five lenses. The first lens is characterized in that the first lens (G1) adopts a single convex lens, the diameter (R1) of the first lens (G1) is 5.1+/-0.015mm, the thickness of the edge (TE1) is 0.38mm, and the thickness of the center (TC1) is 0.80+/-0.02mm. The first lens for the miniature combined light optical instrument containing the five lenses has the advantages that the miniature effect is realized, the resolution is high, the defect of imaging distortion of the miniature lens is effectively overcome, the color recovery degree is high, the imaging is 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 comprising 5 pieces of eyeglasses.
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 comprising 5 pieces of eyeglasses.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 comprising 5 pieces of eyeglasses, it is characterized in that described first eyeglass G1 is single convex eyeglass, the diameter R1 of described first eyeglass G1 is 5.1 ± 0.015 millimeters, and edge thickness TE1 is 0.38 millimeter, and center thickness TC1 is 0.80 ± 0.02 millimeter.
The radius-of-curvature of the thing side mirror face S1 of described first eyeglass G1 is 13.7037 millimeters, and the image side minute surface S2 of the first eyeglass G1 is plane, and the refractive index of the first eyeglass G1 is 1.801658 ± 0.0005, and abbe number is 44.26 ± 0.5%, and optics bias is 60 〃.
The invention has the beneficial effects as follows:
The micro combined optical system comprising 5 pieces of eyeglasses of the present invention achieves miniaturization, high resolving power with the first eyeglass, 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.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As Fig. 1, comprise micro combined optical system first eyeglass for 5 pieces of eyeglasses, described first eyeglass G1 is single convex eyeglass, and the diameter R1 of described first eyeglass G1 is 5.1 ± 0.015 millimeters, edge thickness TE1 is 0.38 millimeter, and center thickness TC1 is 0.80 ± 0.02 millimeter.
The radius-of-curvature of the thing side mirror face S1 of described first eyeglass G1 is 13.7037 millimeters, and the image side minute surface S2 of the first eyeglass G1 is plane, and the refractive index of the first eyeglass G1 is 1.801658 ± 0.0005, and abbe number is 44.26 ± 0.5%, and optics bias is 60 〃.
Embodiment recited above is only be described the preferred embodiment of the present invention; not the spirit and scope of the present invention are limited; do not departing under design concept prerequisite of the present invention; the various modification that in this area, common engineering technical personnel make technical scheme of the present invention and improvement; all should fall into protection scope of the present invention, the technology contents of request protection of the present invention is all recorded in detail in the claims.
