Embodiment Construction
[0022] see figure 1 , the present invention provides a telecentric optical system with ultra-low distortion and large field of view, the optical system includes a first negative lens 1, a first positive lens 2, a second negative lens 3, a diaphragm 7, and a third negative lens 4. The second positive lens 5 and the third positive lens 6; the first negative lens 1, the first positive lens 2, the second negative lens 3, the diaphragm 7, the third negative lens 4, the second positive lens 5 and the third The positive lens 6 is sequentially arranged on the same optical path 10 .
[0023] In order to enable the optical system provided by the present invention to obtain high-precision imaging quality, the optical system also includes a bandpass filter 9, which can be placed before the first negative lens 1 or before the third positive lens 1. After the lens 6, it is on the same optical path 10 with the first negative lens 1, the first positive lens 2, the second negative lens 3, the...
