Wall is used to coordinate with the lens barrel internal face of camera lens, in the middle part of first spacer ring on direction from the bottom to top successively at least formed with
First cavity, mounting seat and loophole；
First eyeglass, in the mounting seat；
Second eyeglass, in first cavity；
Second spacer ring, in first cavity, and above second eyeglass；
The area of section of first cavity is more than the area of section of the mounting seat, and the area of section of the mounting seat is big
In the area of section of the loophole, the area of section of the loophole is gradually reduced on direction from the bottom to top.
Further, lens assembly described above also includes the 3rd eyeglass located at first cavity, the 3rd eyeglass
Upper surface contacted with the lower surface of first eyeglass, the lower surface of the 3rd eyeglass contacts with second spacer ring.
Further, the first eyeglass described above is biconvex lens, and second eyeglass and the 3rd eyeglass are concave-convex lens,
With first lens sticker by setting, the convex surface of the 3rd eyeglass and the second eyeglass is relative to be set for the concave surface of 3rd eyeglass
Put.
Further, the second spacer ring described above is shaped as annular, and second eyeglass and the 3rd eyeglass are in edge shape
Into concave surface, concave surface of second spacer ring respectively with second eyeglass and the 3rd eyeglass contacts.
Further, lens assembly described above also include point a cushion rubber, described cushion rubber be located at the second spacer ring bottom and
The junction in the first cavity inner wall face.
Further, the first spacer ring described above also includes being formed at the second cavity above the loophole.
Further, described above cushion rubber is ultraviolet cured adhesive circle.
On the other hand the embodiment of the present invention provides a kind of fish eye lens, including for setting the lens barrel of eyeglass, in addition to
Lens assembly described in any of the above-described, the perisporium of the first spacer ring of the lens assembly and the internal face of lens barrel, which coordinate, to be installed.
The embodiment of the present invention is by providing the first spacer ring so that as the first eyeglass and the camera lens key position of the second eyeglass
Installation in advance can be completed in the first spacer ring, then the first spacer ring is installed in the lens barrel of camera lens again, in the first spacer ring
First eyeglass and the second eyeglass and other eyeglasses in lens barrel are relatively independent, reduce eyeglass and spacer ring assembles not positive situation,
Improve product yield；Secondly, the first eyeglass and the second eyeglass is replaced to bear other optical elements in lens barrel by the first spacer ring
Pressure, the first spacer ring where the first eyeglass, the second eyeglass and the second spacer ring is internally formed relatively independent space so that quick
The pressure that sense eyeglass is born is smaller, reduces the risk of rupture of sensitive eyeglass, can effectively save after cost；Meanwhile first chamber
The area of section of body is more than the area of section of mounting seat, and the area of section of mounting seat is more than the area of section of loophole, loophole
Area of section be gradually reduced on direction from the bottom to top, make lens assembly of the present utility model that there is optimal thang-kng amount,
Eyeglass corresponding to cooperation can realize optimal light refraction effect.
