X-ray telescopes help provide a view of the universe that cannot be seen in optical wavelengths. These telescopes provide observations of high energy processes that emit x-rays, processes that are not visible in optical light. Astrophysicists will benefit from new telescopes that can allow insight into the early universe which will create a better understanding of how the universe became what we see today, in terms of its composition and overall structure. However, optics such as those of the Chandra X-ray Observatory are no longer feasible due to practical limitations. Selective deposition via DC magnetron sputtering can provide an alternative to the traditional grinding and polishing technique that was used to create Chandra’s x-ray optics. This method can also correct the figure of a thermally formed optic such as those currently being developed for the Constellation-X mission. Advantages to this technique include the ability to fabricate a larger and lighter optic which is more cost efficient.
