This design enables real-time, dynamic configuration of the field of view for targeted spectroscopy of magnetically active regions and full-disk observations. Optical efficiency was validated through simulations and laser testing. Destructive window removal allowed for detailed structural analysis, confirming the elimination of central vias present in previous models.","authors_text":"Christian Robles, Suvrath Mahadevan","cross_cats":["astro-ph.EP","astro-ph.SR"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.IM","submitted_at":"2026-01-30T17:02:36Z","title":"HEP digital micromirror devices for precision solar spectroscopy"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2601.23176","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:d439b34246221b196853432ab0fab5baf981ec57ccbbe34d9eecd12f53a34c36","target":"record","created_at":"2026-08-04T01:58:47Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"ca453a797b1082d8e837906a6f48b5194952d4211b02ce1c863c996437766904","cross_cats_sorted":["astro-ph.EP","astro-ph.SR"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.IM","submitted_at":"2026-01-30T17:02:36Z","title_canon_sha256":"e405beb5953e37073b642e237db8a7ad146fcea635fe1c0c4665b6205ff8c0d6"},"schema_version":"1.0","source":{"id":"2601.23176","kind":"arxiv","version":1}},"canonical_sha256":"c7a1e2fa2852687b4a63faf12316b97c4b560f89fb132fa89b428e9d3cd106d2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c7a1e2fa2852687b4a63faf12316b97c4b560f89fb132fa89b428e9d3cd106d2","first_computed_at":"2026-08-04T01:58:47.695617Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-08-04T01:58:47.695617Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"2a0zPsjk3hALuDdECHGUvscdXyC97Py1aZnthNE4K1y/xbYUNEcniMBKrbXJJHT8uNYk6FcLjhbuy7cD/dlBBw==","signature_status":"signed_v1","signed_at":"2026-08-04T01:58:47.697074Z","signed_message":"canonical_sha256_bytes"},"source_id":"2601.23176","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d439b34246221b196853432ab0fab5baf981ec57ccbbe34d9eecd12f53a34c36","sha256:84b68dac9205b23462ec9adf354b35a2e286334104c502a91c4aa707dcb4b6b0"],"state_sha256":"9c2915d8c3a6790d9e966f9dc6eea025c6b2a6850852f3b63b3c995e872f1ce9"}
