Outline of Final Research Achievements |
This research aims at developing a grism with high throughput and heat cycle durability for improving efficiency of astronomical observations in long mid-infrared wavelengths. Anti-reflection is important for maximizing throughput, and heat cycle durability is also required for use in infrared astronomical instruments. Moth-eye structure is expected to meet these requirements, and its formation is employed for the anti-reflection technique. By optimizing fabrication processes, a double-sided moth-eye silicon grism is successfully obtained.
