In order to design a large aperture primary mirror with the diameter of 1150 mm
the parameters impacting on gravity deformation of the mirror were analyzed and discussed in detail
including material selection
diameter-thickness ratio
the number of the support points
location selection and lightweight structure
etc. A novel space mirror structure system was put forward
and its back was opened and supported by six points on back. The dynamic and static and thermal characteristics were analyzed based on the finite element method. Analysis results showed the surface figure accuracy reached to RMS 14.5nm under the action of gravity load along the optical axis direction and the first-order natural frequency was 214Hz which met to the designed indexes requirements.

Structural design of large aperture mirror is one of the key technologies for space telescope development. To meet the requirements of high stiffness
strength and thermal dimensional stability
some factors such as support scheme
materials selection
lightweight design and flexible support design were taken into account. The three supports location of the mirror was determined according to the modal analytical solution. By adjusting the parameters of flexure hinge
influences of gravity
assembly stress and thermal stress on the mirror were reduced obviously. Finite element analysis (FEA) results indicate that the surface accuracy reach to rms10.2nm and 10.8nm under the gravity along optical axis direction and 5C uniform temperature rise respectively
the fundamental frequency of the mirror component is 268Hz. Dynamics test shows that the first order natural frequency is 256Hz
which shows an error less than 5% compared to FEA results. (2013) Trans Tech Publications

Tandem gratings of double-dispersion mount make it possible to design an imaging spectrometer for the weak light observation with high spatial resolution
high spectral resolution
and high optical transmission efficiency. The traditional tandem Wadsworth mounting is originally designed to match the coaxial telescope and large-scale imaging spectrometer. When it is used to connect the off-axis telescope such as off-axis parabolic mirror
it presents lower imaging quality than to connect the coaxial telescope. It may also introduce interference among the detector and the optical elements as it is applied to the short focal length and small-scale spectrometer in a close volume by satellite. An advanced tandem Wadsworth mounting has been investigated to deal with the situation. The Wadsworth astigmatism-corrected mounting condition for which is expressed as the distance between the second concave grating and the imaging plane is calculated. Then the optimum arrangement for the first plane grating and the second concave grating
which make the anterior Wadsworth condition fulfilling each wavelength
is analyzed by the geometric and first order differential calculation. These two arrangements comprise the advanced Wadsworth mounting condition. The spectral resolution has also been calculated by these conditions. An example designed by the optimum theory proves that the advanced tandem Wadsworth mounting performs excellently in spectral broadband. 2012 Optical Society of America.
