- Description
- The purpose of this modification is to post questions and answers. Question: Please let me know if you can accept metal and if so, what type of temperature this part might see Answer: The mirrors are for a sounding rocket flight to observe soft X-ray/EUV wavelengths around 10 nm and will experience full sunlight for about 7 minutes. The Inrad website quotes "sub-20 Å surface roughness". Our requirement is 3 Å RMS surface roughness on spatial scale below 1000 nm. If their process can achieve that, we might consider metal, but would need to evaluate a number of other factors such as the deposition of a multilayer coating (to be supplied by another vendor) on the front surface. Question: Why is the reflective coating on the rear plano surface, rather than the front concave surface? Answer: For alignment purposes - the front surface is to be coated by another vendor with a multilayer to reflect EUV wavelengths around 10 nm. Question: What is your preferred material (fused silica, ULE or Zerodur)? Answer: Whatever material/process combination can achieve 0.3 nm RMS surface roughness on spatial scales below 1000 nm (as well as the other specifications). Question: What is the application? Answer: A telescope mirror for an EUV imaging spectrograph (EUNIS) to fly on a sounding rocket. It will be in full sunlight for about 7 minutes.
