  Title: Dual Wavelength Coated Ultra High Reflectivity Mirrors
  BACKGROUND
  The Quantum Measurement Division (QMD) at the National Institute of Standards and Technology (NIST) provides the fundamental basis for the measurement of mass, force, and vibration in the United States by maintaining and modernizing primary standards linked to the International System of Units (SI). The Division performs leading-edge research to develop advanced measurement technologies and provides calibration services that support U.S. industrial productivity and ensure equity in trade. The QMD has a requirement for dual-wavelength high-reflectivity mirrors. These mirrors will be integrated into primary acoustic measurement systems, in support of the Division-s mission to deliver accuracy and traceability of acoustic measurements.
  In order to meet the mission indicated above, the Mass and Force Group requires a set of (12) high reflectivity mirrors, operating at the wavelengths 1560 nm and 390 nm.
  The minimum requirements are as follows:
  Line Item 0001:
  Description: Dual-band high-reflectivity mirrors

  Technical Specifications:
  Angle of incidence: 0 degrees
  Reflectivity at 1560 nm: 99.97 % +/- 0.005 %
  Reflectivity at 390 nm: 99.97 % +/- 0.005 %
  Optical losses (scattering, absorption) of beam incident on front surface: 0.015 % or lower
  Backside AR coating: 390 nm + 1560 nm
  Substrate diameter: 7.75 mm
  Substrate thickness: 4mm - 6mm
  Frontside ROC: 1 m
  Backside ROC: Plano, optical polish
