The Department of Commerce, specifically the National Institute of Standards and Technology (NIST), is seeking to acquire a THz Quantum Cascade Laser (QCL) Module to enhance its measurement capabilities in research involving carbon nanotube coatings. The QCL Module must meet specific technical specifications, including an output frequency of approximately 4.8 THz and a continuous wave power of at least 2 mW, and it should be compatible with an existing system. This procurement is crucial for advancing scientific research and calibration activities at NIST, ensuring high standards in measurement science and technology. Interested vendors should contact Angela Hitt at angela.hitt@nist.gov or call 303-497-7305, with delivery required within 14 weeks after order acknowledgment and payment contingent upon successful completion of performance tests.
