The general philosophy for instrument procurement is to develop within OSIRIS institutions the system and subsystem specifications, the instrument error budgets, and the subsystems design up to Preliminary Design level. The subsystems Detailed Design and Fabrication, including tests, is contracted to external companies by the Instituto de Astrofísica de Canarias (IAC). This procedure allows optimization of the available engineering resources within the IAC and the Instituto de Astronomía of the Universidad Nacional Autónoma de México (IA-UNAM), heavily involved in other ground-based and satellite-borne astronomical instruments, while decreasing the overall project duration.
There are several exceptions of this guideline:
-
The fabrication of part of the camera lenses by the IA-UNAM.
The masks and mask casette, which are fully designed and manufactured at the IAC.
The instrument structure, which will be developed to Detailed Design level by the IAC to avoid interface definition by the rest of teh sub-systems to be attached to the structure.
The detector control (IAC).
The instrument control (IAC).
The instrument assembly, integration, and verification (AIV) and Commisssioning (IAC and IA-UNAM).
Below is a guideline to our main contractors.
