Combined Sources Sought Notice and Notice of Intent to Award a Sole Source Contract for Ultralow Loss Mid-IR Optics with Hybrid Crystalline Coatings

Notice ID: NIST-SS26-CHIPS-158

Contract Opportunity Type: Sources Sought

Response Date: 7/23/26

Product Service Code (PSC): 6640

BACKGROUND

The National Institute of Standards and Technology (NIST) is conducting market research to identify alternative sources that (a) are capable of meeting NIST’s minimum requirements for the following commercial products and commercial services and (b) would be interested in competing for that requirement: The CHIPS Metrology Program includes research in Grand Challenge 1, Metrology for Materials Purity, Properties and Provenance. To address this Grand Challenge, the project Optical Impurity Analysis of Semiconductor Gases for Enhanced Quality Systems seeks to purchase Ultralow Loss Mid-IR Optics with Hybrid Crystalline Coatings to perform ultrasensitive cavity ring-down and cavity-enhanced spectroscopy on low-temperature (180 K to 220 K) gas-phase samples. The project is led by the Chemical Science Division of the NIST Material Measurement Laboratory, the nation’s premier metrology laboratory for measurement science, standards, technology, and data in the area of chemical sciences

To improve sensitivity in laser absorption spectroscopy, optical cavities are used to enhance the interaction pathlength between a laser source and a gas-phase sample. Here we aim to detect trace impurities in gas-phase samples relevant to the semiconductor industry. Therefore, we require high reflectivity mirrors with low absorption and scattering loss that efficiently transmit and store laser light. The overall goal is the trace detection of small molecules like carbon dioxide (CO2) and carbon monoxide (CO) in bulk zero gases like CO2, nitrogen (N2) and argon (Ar) at the parts-per-trillion level (1 part in 1012). To achieve this goal, we seek Ultralow Loss Mid-IR Optics with Hybrid Crystalline Coatings for Low Temperature for use at a center wavelength near 4500 nm and a temperature near 200 K

NIST has not yet determined its acquisition strategy for this requirement and encourages interested sources to respond to this Notice.

If NIST’s market research indicates there are alternative sources that are capable and interested in competing to fill this requirement, separate and apart from [ThorLabs INC VCJKYBSL8DL8] then NIST will consider conducting a competitive acquisition in accordance with law and regulation. To be clear, NIST’s identification of [Thorlabs INC] in this Notice does not constitute a binding commitment or obligation for it to conduct a sole source procurement with [Teledyne Princeton Instruments] for this requirement.
