Relay lens with small Chart, wide test simulation distance and long working distance

The invention discloses a relay lens with a small Chart width test simulation distance and a long working distance, and the relay lens comprises lenses which are sequentially arranged from a tested module to a Chart plate along an optical axis, the lens 1, the lens 2, the lens 4, the lens 6 and the lens 7 are concave-convex lenses, the lens 3 is a convex-concave lens, the lens 5 is a plano-concave lens, and the lens 5 is a plano-concave lens. The lens I is a positive focal lens, the concave surface of the lens I faces the detected module, and the convex surface of the lens I faces the Chart plate; the lens II is a positive focal lens, the convex surface of the lens II faces the detected module, and the concave surface of the lens II faces the Chart plate; the convex surface of the lens III faces the detected module, and the concave surface of the lens III faces the Chart plate; the fourth lens is a positive focal lens, the concave surface of the fourth lens faces the detected module, and the convex surface of
