Palomar 200" Telescope Reflectivity Information

February 2012 Top-end Refurbishment

  • Measured reflectivity of new F/15.7 M2 coating = 91% at 500 nm wavelength
    • This is measured with a hemispherical reflectometer and is not exactly the astronomical reflectivity as it does not measure the scatter component correctly
    • Reference: Dan McKenna for more information
