Wavelength Meter Procurement

The purpose of this sources sought notice is to conduct market research and identify potential sources of commercial products/services that satisfy the Government’s anticipated needs.

BACKGROUND The National Institute of Standards and Technology (NIST), the Fundamental Thermodynamics group at the Sensor Science Division is conducting Standard Photonic Thermometer (SPoT) project. The main focus of the project is to develop the next-generation chip-scale photonic temperature metrology that can replace Standard Platinum Resistance Thermometers (SPRTs), reduce the temperature calibration chain and sensor ownership cost. The SPoT project, pursued by The Fundamental Thermodynamics group, is a multi-year/multi-million effort funded by both NIST-on-a-Chip (NOAC) and Air Force. The timely achieving project’s milestones is NIST-mission-critical task and is one of the priorities of the Physical Measurement Laboratory (PML). One of the essential milestones of Standard Photonic Thermometer is to develop both high-resolution photonic readout capabilities, as well as cost-efficient and deployable photonic readout systems. To achieve these essential for the project milestones, the Fundamental Thermodynamics group has a critical need for one (1) high-resolution and one (1) low-resolution wavelength meters. The high-resolution wavemeter should come with 4-channel optical switch and 4-channel PID controller. Both instruments must be from the same manufacture to ensure software compatibility. The instruments are essential for achieving the precision and stability necessary in next-generation temperature metrology NIST is seeking information from sources that may be capable of providing a solution that will achieve the

objectives described above, in addition to the following essential
