Focus lens structure containing group can disassemble

The utility model discloses a focus lens structure containing group can disassemble, its technical scheme's main points are including the picture frame, the second lens of be equipped with glass spheric glass, first lens in the picture frame in proper order, can disassemble the group, a plurality of air gap is sensitive, can disassemble the group including the spacer ring, the spacer ring internal fixation has the insensitive third lens of at least one air gap. The utility model discloses bad that the lens group produced has immediately been improved to disassemble back reuse to independent group to the performance defective products, improving the performance yield in the time of the reduction labour cost, solitary group structure makes the external diameter of glass lens reduce to lens cost reduction, and solitary group top surface can direct assemblage lens, has played the air gap's between two lenses effect. Improve the percent of pass when carrying out environmental test to the camera lens, prolonged lon
