结合实际需要设计了一种精度高、便携性好，用于检测多光轴光学系统光轴间平行性的检测仪器。该仪器能够实现可见、红外与激光不同谱段任意两个光学成像系统间的光轴平行性检测。与同类其他仪器比较，该仪器的特点是光学系统结构均采用全反射设计，避免使用红外光学玻璃，在设计中减小和去除了影响仪器精度的一些因素，例如：去除了平面镜2个表面楔角α的影响。仪器的主体采用完全对称的结构和积木式的组装方式，保证了仪器经温度循环实验和振动试验后检测精度优于5″，满足使用要求。

A high‐precision ,good‐portability testing instrument was designed ,which could de‐tect optical axis'parallelism of multi‐axial system according to practical needs .The instrument was able to test the nonparallelism of system's optical axis among visible ,infrared and differ‐ent laser spectrum bands .Compared with similar instruments ,the instrument was character‐ized by utilizing total reflection structure design and did not use infrared optical glass .Mean‐w hile ,through optimization design ,the instrument avoided some disadvantageous factors that influenced precision ,such as the influence of plane mirror's wedge angle α.Main structure of the instrument used completely symmetric structure design and cordwood assembly way to en‐sure that the test precision superiored to 5″,after temperature cycle test and vibration test . T he instrument meets customer requirements .
