摘要：
We present two designs of a filter mounting structure for the Near-Infrared Imaging Photometer (NIP) planned for the Euclid dark energy space mission. The three large near-infrared filters - with a 127 mm diameter, 12 mm thickness and a 330 g mass per element - are challenging to mount. We present the design considerations, finite element analysis and results from the first prototyping campaign of these structures. The rationale behind the down-selection between the two designs is detailed and we conclude with recommendations on future developments of mounts of this type. The results presented here are based on work performed during the Euclid Assessment Study.
