Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
It as depicted in figs. 1 and 2, is respectively a kind of structural representation of electron telescope object lens provided by the utility model
Figure and schematic cross-section.The electron telescope includes the first lens group 1 set gradually along optical path, intermediate lens 2, with object lens
Two lens groups 3 and sensor 4, the utility model is by using above-mentioned arrangement form, so that the enlargement ratio of object lens greatly improves,
8 times can be up to, it is big to solve existing electron telescope color difference, and viewing medium and long distance scenery is unintelligible and enlargement ratio is inadequate
The problem of.
Specifically, the first lens group 1 includes the first lenticular lens 11, the first single side concavees lens 12 and the first single side convex lens
Mirror 13, the first lenticular lens 11 and the first single side concavees lens 12 are glued；Intermediate lens 2 includes intermediate single side convex lens 21 in
Between single side concavees lens 22, intermediate single side convex lens 21 and the first single side convex lens 13 are opposite；Second lens group 3 includes second two-sided
Convex lens 31, the second single side concavees lens 32 and the second single side convex lens 33, the second lenticular lens 31 and the second single side concavees lens
32 is glued, and the second lenticular lens 31 is opposite with intermediate single side concavees lens 22, and the second single side convex lens 33 is opposite with sensor 4.
Object lens provided by the utility model are reduced to five by conventional seven, add as 8 times by that can amplify 3~5 multiplications originally, so that its
Have the characteristics that color difference is small, dispersion is few, distortion is small and imaging clearly, the CCD demand of big resolution ratio can be met.Using above-mentioned glue
The connection type closed and (should first carry out plated film before glued), it is red to may make that the first lens group 1 and the second lens group 3 can meet simultaneously
Outside, the demand of night vision and visible light on daytime.
Specifically, the diameter of the first lens group 1 and intermediate lens 2 is all larger than the diameter of the second lens group 3, this is because light
By the first lens group 1 and intermediate lens 2 optically focused can occur for line, and the spread scope of light becomes smaller, it is therefore desirable to the second lens group 3
Diameter it is matched.
Specifically, which further includes main support 5, and the first lens group 1, intermediate lens 2 and second are thoroughly
Microscope group 3 is set to inside main support 5, and the outside of main support 5 is equipped with silica gel sheath 51, for protecting main support 5.
Specifically, the first washer 52 is equipped between the first lens group 1 and intermediate lens 2, so as to ensure the first lens
Group 1 has certain interval with intermediate lens 2, while can also limit to intermediate lens 2.
Specifically, the first pressing ring 61 is equipped on the outside of the first lens group 1, the first pressing ring 61 is threadedly coupled with main support 5, preferably
The inside of main support 5 is threadedly connected to for the first pressing ring 61, so that the first lens group 1 is limited and be fixed.
Specifically, second packing ring 53 is equipped between the first lens group 1 and the first pressing ring 61, it can be ensured that the first lens group 1
It is flexible fixed by second packing ring 53, it avoids the occurrence of hard contact and the first lens group 1 is damaged.
