Preferred version of the present utility model, optics amplification imaging system lower end is provided with first lens over against cemented cubic prism, second lens, the 3rd lens, the 4th lens, the 5th lens, the 6th lens placed successively from top to bottom with optical axis with first lens.

Preferred version of the present utility model, optics amplification imaging system upper end is connected with the CCD monitor.

Preferred version of the present utility model, first right-angle prism and second right-angle prism are semi-transparent, 45 ° of prisms of half reflection.

Preferred version of the present utility model, the 7th lens are made up of packing ring convex lens at interval by two.

Preferred version of the present utility model, the 8th lens are three convex lens by the packing ring interval.

Preferred version of the present utility model is provided with between the 8th lens and the reflective mirror by the fixing delustring diaphragm of diaphragm trim ring.

Preferred version of the present utility model, square rod is fixed by trim ring.

Owing to adopt technique scheme, the high-resolution that the utility model provides checks that lens construction has following beneficial effect, and illuminator and optical amplification system are combined as a whole by mechanical part and one group of prism, has reached high resolving power on performance.This camera lens directly connects light source with optical fiber when using at every turn after the debugging of dispatching from the factory, do not need to debug light source.Little, the easy to use practicality of small product size.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.Though the utility model will be described in conjunction with preferred embodiment, should know, do not represent that the utility model is limited among the described embodiment.On the contrary, the utility model will be contained alternative, modified and the equivalent in the scope of the present utility model that can be included in attached claims qualification.

Referring to Fig. 2, the high-resolution of introducing checks that lens construction generally is used for detections such as optics AOI, semiconductor AOI, FPD AOI, PCB AOI, materials A OI and uses camera lens here, yet should know that the utility model also can be used for the camera lens of other structures.High-resolution described herein checks that lens construction comprises optics amplification imaging system 1, optics amplification imaging system 1 is become by the same optical axis lens combination of placing successively from bottom to top, is followed successively by first lens 9, second lens 10, the 3rd lens 11, the 4th lens 12, the 5th lens 13, the 6th lens 14.Be provided with the cemented cubic prism that forms with first right-
