Description

**THIS IS A COMBINED SOURCES SOUGHT NOTICE AND NOTICE OF INTENT TO SOLE SOURCE.

BACKGROUND

The Fundamental Thermodynamics group at the Sensor Science Division is conducting the Photonic ac-dc Thermal Transfer Standard (PTTS) project. The main focus of the project is to develop the next-generation chip-scale photonic ac-dc difference metrology that can replace legacy thin-film multijunction thermal converters (MJTCs), reduce the ac-dc difference calibration chain, and lower sensor ownership costs.

The PTTS project, pursued by the Fundamental Thermodynamics group, is part of the NIST-on-a-Chip (NOAC) program. Achieving the project’s milestones in a timely manner is a NIST-mission-critical task and a priority of the Physical Measurement Laboratory (PML).

One of the essential milestones of the Photonic ac-dc Thermal Transfer Standard (PTTS) is to develop a high‑precision, deployable photonic readout system. This capability is critical for the PTTS project, providing the accuracy and stability needed to advance photonics-based ac-dc difference metrology toward practical implementation. To achieve these milestones, the Fundamental Thermodynamics group has a critical need for one (1) high-speed lock-in/servo system. This instrument is essential for enabling scalable and practical solutions for next-generation ac-dc difference metrology. Delaying or not approving this procurement would hinder progress on key deliverables of the NOAC PTTS project. Timely acquisition is vital to meet technical objectives and keep the project on track to deliver advances in ac-dc difference metrology.

NIST is seeking information from sources capable of providing a high-speed lock-in/servo system to support the NOAC Photonic ac-dc Thermal Transfer Standard (PTTS) project.

If no alternative sources are identified, the Government intends to issue a Sole Source Award to Liquid Instruments Inc. (UEI: MS6AHD4EF8D7) under the authority of FAR 12.102(b). The North American Industry Classification System (NAICS) code for this acquisition is 334516.

The high-speed lock-in/servo system must meet the following minimum specifications:
