Abstract:Tostudy the effects of thetemperature variation on the optical system,and discuss the method of athermalisation,the effects were analyzed byusing the coefficient of thermal expansion and with themethod of raytracing. The thermal effects is distinct, however thermalisationisfeasible. The thermal effects can not be ignored and the analysis ofthe effects can becompleted with the method presented. (WR&Vt4R
