In this paper, the concept of compensa Hon to null tests using compensators in astronomical optics is advanced. As for Fig. 1, formula (1) and formula (2), if the parameters of the compensator A have been so selected as to yield b1-a1, only, we define it as the first order compensator. If to yield b1=a1 and b2=a2 simultaneously, we define it as the second order compensation, etc.And we suggest three following principle points about the design of null test systems: 1.

In this paper, the concept of compensa Hon to null tests using compensators in astronomical optics is advanced. As for Fig. 1, formula (1) and formula (2), if the parameters of the compensator A have been so selected as to yield b1-a1, only, we define it as the first order compensator. If to yield b1=a1 and b2=a2 simultaneously, we define it as the second order compensation, etc.And we suggest three following principle points about the design of null test systems: 1. Because the selected focal ratio of the primary of modern reflecting telescope diminishes steadily, and more and mose higher order aspheric systems of excellent image quality have been designed, we should lay emphases on the second order, or higher order compensators in later design and research work. 2. The compensators should consist of small size optical elements. 3. Fig. 3, Fig, 4 and Fig. 5 are the principle configurations for testing concave surfaces, convex surfaces and aspheric plates. In any above arrangement, B is a spherical mirror to converge the beam and A is a small size optical system providing the compensation of the requested order.It is put forward in this paper, that the applicable range of a compensator can be enlarged, by shifting optical elements and changing object distance. Let's take the Of-fner compensator of Chinese 2.16-meter primary as an example. Its structure data are given in Table 1. When the refractive index changes from 1.5163 to 1.5313, it is only needed to change S1 to -580.85785, d2 to 505.45925 and d4 to 12998.533. When e2 of the primary changes from 1.0951347 to 1, it is only needed to change S1 to-678.56510, d2 to 504.25088 and d4 to 12961.746. When the radius of curvature changes from -12960 to -13960, it is only needed to change & to -607.29751, d2 to 522.64348 and d4 to 13990.144. In above cases, almost the same good effects of compensation are obtained. Even if the refractive index and the parameters of a primary change far more, very good results can be still obtained by changing S1, d2 and d4 correspondingly. On the other hand, if the changes of refractive index and the parameters of primary are small, it is already good enough by changing S1, and d4 only.In addition, it is also mentioned that the better method is to compromise by defining a reasonable merit function for optimization during the later stage of the design process of null tests using compensators. The special programme we developed for null tests is also introduced briefly. All results in this paper are obtained by the programme.

本文对天文光学中的补偿检验法提出了补偿级的概念,提出了我们对设计补偿检验系统的原则性意见,提出了应用移动光学元件和改变物距的方法扩大补偿器应用范围的想法,并以一个Offner补偿器为例作了实际计算,只要改变点光源到透镜的距离和两透镜的间隔,可使同一个补偿器适用于比可见光更大的波段中的任一波长,e~2和r值在相当大范围中的各种被检验镜。文中也简要叙述了我们编的补偿检验系统优化程序。

In this paper,compensating test systems for high-order aspherical plates are proposed.The fifth order spherical aberration is applied to solving the initial structure of the compensator.The initial structure of the compensator agrees with the optimal result very well.There are two compensating test systems for the 1 5 m correcting plate of an achromatic Schmidt telescope with a field of view of 2 W =6°.All compensating test systems reach high accuracy,the residual...

In this paper,compensating test systems for high-order aspherical plates are proposed.The fifth order spherical aberration is applied to solving the initial structure of the compensator.The initial structure of the compensator agrees with the optimal result very well.There are two compensating test systems for the 1 5 m correcting plate of an achromatic Schmidt telescope with a field of view of 2 W =6°.All compensating test systems reach high accuracy,the residual of each tested surface is less than λ/100(λ=0 5893 μm).Finally,we discuss the test system errors in detail when the system is misaligned, and put forward an effective method of reducing the test system errors. This method is also applicable to other compensating test systems.

本文提出了检验高次非球面板的基本系统,并把五级球差应用于求补偿器的初始解,用网格法得到的初始解与优化结果符合.文章以口径为15m,视场为6°的施密特望远镜的消色差改正板为例,设计了两个补偿检验系统.被检面的面形残差均小于λ/100.还以消色差施密特改正板一为例,对补偿系统在失调状态下的误差作了详细分析,同时结合实际加工情况,得出了较为宽松的公差要求.

In this paper an approaching method is adopted in marking the Offner compensatory for testing a φ800mm parabolic mirror.According to the actual situation, we fix the parameters, which had already been accurately measured and then optimize the whole system by adjusting the residual parameters to meet practical precision. Thus critical requirement in manufacturing can be alleviated and the processing time can be saved as well.

采用设计、检验、加工交替进行逐步迫近的方案,研制了一套offner补偿检验系统,确保了φ800mm拋物面主镜的检测精度。
