Space coat

摘要

As the use of space-based instruments such as telescopes, satellites and probes increases, a number of companies and research organisations are busy developing innovative coatings for onboard optical components. So, what are some of the most recent advances in the development and application of optical coatings for space- based devices? And, could advances made in the space sector eventually trickle down to other optical coating markets? Unlike the materials used on Earth, optical coatings for space-based applications need to be extremely stable and durable - largely because maintenance and exchange as a result of wear and tear is not easily possible. These requirements mean that space-based optics must be of the highest quality, and often be tailor- made for specific applications. According to Helmut Kessler, managing director at Manx Precision Optics (MPO), this relentless focus on quality often results in space- related products that are at the forefront of the currently feasible specifications.
