Zusammenfassung:The utility model relates to a refraction formula and autocollimator definition and colour difference origin cause of formation demonstration appearance, including light source cover shell (10), simulation demonstration casing (20), entity demonstration casing (30) and light projector board (40), simulation demonstration casing (20) rectangle inboard is equipped with autocollimator principle presentation device (201) and refraction formula telescope principle presentation device (202), the inside two parts from top to bottom that divide into of entity demonstration casing (30), both ends are equipped with one objective (303) and eyepiece (304) respectively around the first half, both ends are equipped with one convex mirror (305) and concave mirror (306) respectively around the latter half. The utility model discloses simple structure, the light exposure in the convenient to use, light source cover shell go into upper and lower two parts of entity demonstration casing, through formation of image reflective an
