STATEMENT OF WORK

Title: Consulting and Design for Microfabricated, Electrical-Substitution Bolometers Date: April 9, 2026

I. BACKGROUND INFORMATION

The Sources and Detectors Group, in the Applied Physics Division, at NIST performs laser power and energy detector responsivity calibrations for the US and the rest of the world. The calibrations range from the single photon level to 100 kW, with wavelengths varying from 193 nm to 10.6 um. The group also performs research to extend measurement capabilities in both power and wavelength, and to develop Nist-on-a-Chip technology that takes precision measurement out of the lab and into the field. The Sources and Detectors group has previously collaborated with the Laboratory for Atmospheric and Space Physics (LASP) to develop microfabricated radiometers for space applications. These instruments show great promise for new applications. NIST is undertaking research to expand the applications of these detectors.

II. PURPOSE

Contractor shall provide bolometer design and operation expertise and expertise to implement modifications to the electronics designs used to operate electrical substitution microfabricated bolometers. NIST has previously collaborated to develop such bolometers, which use detectors fabricated by NIST and packaging and electronics designed by LASP. New applications for these detectors, such as vicarious calibration of Earth remote sensing satellites or operation at different optical power levels, are under development at NIST and will require modifications to the design of LASP’s PBR-R detector package.

PLACE OF PERFORMANCE

Work will be performed at in Boulder, CO.

PERIOD OF PERFORMANCE

August 1, 2026 – July 31, 2027
