This study introduces a vendor table method to estimate telescope sensitivity (PSSN) using single segment data. This approach offers a worst-case scenario for segment polishing specifications, ensuring flexibility for vendors.

Area of Science:

  • Optical Engineering
  • Astronomy Instrumentation

Background:

  • Segmented telescopes require precise surface specifications for optimal performance.
  • Estimating overall telescope sensitivity from individual segment data is challenging.

Purpose of the Study:

  • To develop a statistical method for estimating normalized point-source sensitivity (PSSN) of segmented telescopes.
  • To provide a flexible and practical specification for mirror vendors.

Main Methods:

  • A statistical approach assuming uniform power spectral density (PSD) across all segments.
  • Development and testing of a 'vendor table' for PSSN estimation.
  • Validation using mirror samples for the Thirty Meter Telescope (TMT).

Main Results:

  • The vendor table method provides a worst-case PSSN scenario for statistical random realizations.
  • The method proves practical utility in testing with diverse mirror samples.
  • The TMT plans to adopt this vendor table for M1 segment polishing requirements.

    • Conclusions:

    • The vendor table offers a direct link between segment polishing specifications and science metrics like PSSN.
    • This method provides mirror vendors with flexibility in meeting a single PSSN value.
    • The approach is deemed valuable for individual segment specification in large segmented telescopes.
