Abstract
Disclosed is a third lens for a minitype combined optical system. The diameter (R3) of the third lens (G3) is 6+/-0.02 mm, the edge thickness (TE3) of the third lens (G3) is 0.68 mm, and the center thickness (TC3) of the third lens (G3) is 1.6+/-0.02 mm. By means of the third lens, miniaturization and high resolution are realized, imaging distortion of a minitype lens is effectively avoided, color rendition degree is high, and imaging can be achieved clearly. The minitype combined optical system 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 3rd 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 3rd 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 3rd eyeglass, described micro combined optical system is 6 ± 0.02 millimeters with the diameter R3 of the 3rd eyeglass G3, and edge thickness TE3 is 0.68 millimeter, and center thickness TC3 is 1.6 ± 0.02 millimeters.
Described micro combined optical system is 20.02322 millimeters by the radius-of-curvature of the thing side mirror face S5 of the 3rd eyeglass G3, effective diameter ∮ 5.0, refractive index is 1.801660 ± 0.0005, and abbe number is 44.27 ± 0.5%, centering coefficient is 0.1453, and optics bias is 60 〃.
Described micro combined optical system is 6.810744 millimeters by the radius-of-curvature of the image side minute surface S6 of the 3rd eyeglass G3, effective diameter ∮ 5.5, refractive index is 1.801660 ± 0.0005, and abbe number is 44.27 ± 0.5%, centering coefficient is 0.1453, and optics bias is 60 〃.
The invention has the beneficial effects as follows:
Micro combined optical system of the present invention 3rd eyeglass 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.
