The optical system only consists of three germanium lenses with a "negative-positive-positive" reversed telephoto telecentric structure in the image space.

采用“负-正-正”型式的反远距像方远心光路镜头结构，仅有三块非球面锗透镜构成。

Furthermore, the selection of the double telecentric optical system ensures the correction of the trapezoidal distortion introduced by the tilt object surface.

选择双远心光学结构，便于对倾斜物面所产生的梯形畸变进行矫正。
