“…The maximum MPS (MPS max ) is found to be on the ISM positions with a calculated value of 3.48 MPa (Fig. 6b) which is significantly lower than 10.35 MPa, the micro-yield strength of ZERO-DUR ® with moderate surface treatment conditions (Yoder 2005;SCHOTT AG 2009).…”

The paper aims at obtaining the optimum lightweight configuration for a primary mirror (M1) with honeycomb patterns for a space satellite. The finite element analysis and Zernike polynomial fitting based on the Taguchi Method are applied to the whole optimization process. Geometrical control factors and levels were selected to minimize the ratio of various mass reduction ratios (MRRs) to the product of the corresponding maximum mirror structural deflection and optical surface peak-tovalley wavefront aberrations under launch accelerations. The optimum lightweight M1 with a MRR of 0.5 and a mass of 9.72 kg is attained and a mirror blank based on this design was manufactured. The performance of the optimum lightweight mirror is simulated and the simulation results satisfy the requirements of space specifications.

“…The thermal expansion coefficient of fused silica is nearly zero (0.5×10 -6 /℃) compared to that of ordinary optical glass such as BK7 (7.1×10 -6 /℃) [5,6]. In that sense, this design approach can also be termed zero-expansion athermalization.…”

A compact imaging spectrometer (COMIS) is currently under development for use in the STSAT3 microsatellite. COMIS images the Earth's surface and atmosphere with ground sampling distances of ~30 m in the 18~62 spectral bands (4.0~1.05 μm) for the nadir looking at an altitude of 700 km. COMIS has an imaging telescope and an imaging spectrometer box into which three electronics PCBs are embedded. These are designed into a single assembly with dimensions of 35(L) × 20(W) × 12(H) cm 3 and a mass of 4.3 kg. Optomechanical design efforts are focused on manufacturing ease, alignment, assembly, testing and improved robustness in space environments. Finite element analysis demonstrates that COMIS will survive in launch and space environments and perform the system modulation transfer function (MTF) in excess of 0.29 at the Nyquist frequency of the CCD detector (38.5 lines-per-mm).

“…This tutorial assumes that the reader is familiar with basic GD&T/GPS practices, so we can focus on the unique practices associated with describing optical components. As a mechanical part, an optical component can be described to some extent under the standards listed above [2]. However, the unique aspects of optical components require additional standards to accurately describe the part to be made.…”

This tutorial provides a brief introduction to the ISO 10110 optical drawing standard. The indications included on an ISO 10110 optical drawing are defined, and an example drawing is provided to illustrate how the information is commonly presented. To aid the designer who may not be familiar with the capabilities of optical shops, a set of specification values are provided, which illustrate easy, typical, and difficult values to achieve in fabrication. The same type of information is presented for lens dimensions. Finally, a set of design best practices are presented to aid in reducing fabrication difficulty and cost.
