Development of Aluminum Mirrors for Metal Optics Applications

Research and development of aluminum mirrors for metal optics applications conducted by Masaki Mori at ICRR, Univ. Tokyo, in collaboration with Akiko Kawachi (Tokai), Midori Yuasa, and Michiko Ohishi. Presented at CTA meeting in Berlin, May 4-5, 2006. The study includes mirror materials, reflectivity measurements, weathering tests, and the need for anti-dew mechanisms. The summary outlines the progress in mirror development and considerations for real-world applications.

  4. Sample aluminium mirror Without coating With SiO coating With Al+SiO coating Just machine-ground (no polishing) !

  5. Reflectivity Cf. Literature

  6. Surface measurement

  7. 3D measurement

  8. Focus Image size in X-axis Image size in Y-axis

  9. Image Integrated CCD counts 89% within 0.1 degree

  10. Weathering Reflectivity of a sample mirror before and after exposure in Woomera

  11. Summary • We are developing aluminium mirrors by simple manufacturing process. • Samples show modest quality (89% light within 0.1 degree). • Weathering tests are going on. • Anti-dew mechanisms should be developed. • In real use we may form a segment from multiple mirrors to save the number of tuning mechanism.
