Abstract
The design of a new kind of reflective field lens was introduced. Taking the utilization conditions, the principle design and the structure into account, the objective lens and the image lens were designed to consist of two spherical reflective image lenses with same sphere center and same curvature radius (R1=R3=-5000 mm), and the calculated depth of the micro-concavity was about 0.002mm. This field lens has a particular effect-broadening band in addition to he normal action of transmissive field lens in the optical system.
