Dual Wavelength Coated Ultra High Reflectivity Mirrors   2

Background
The Quantum Measurement Division (QMD) at the National Institute of Standards and Technology (NIST) is responsible for maintaining and modernizing primary standards linked to the International System of Units (SI).

The division conducts research to develop advanced measurement technologies and offers calibration services that enhance U.S. industrial productivity and ensure equity in trade. The QMD requires dual-wavelength high-reflectivity mirrors for integration into primary acoustic measurement systems, supporting its mission to deliver accuracy and traceability in acoustic measurements.

Work Details
The contract involves providing twelve (12) dual-band high-reflectivity mirrors with the following 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):** 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

All items must be new; used or remanufactured equipment will not be considered for award. The mirrors must be shipped in original manufacturer’s packaging with all original documentation and software.

Period of Performance
The period of performance is twelve (12) weeks after receipt of order.

Place of Performance
National Institute of Standards and Technology, Shipping and Receiving (Div 684.07), 100 Bureau Drive, Building 301, Gaithersburg, MD 20899.
