The Department of Commerce, specifically the National Institute of Standards and Technology (NIST), intends to issue a Sole Source Award to Conoptics, Inc. for an Electro Optic Modulator (EOM) System, which is essential for characterizing semiconductor defects. This system will enhance a custom Time Domain Thermoreflectance (TDTR) instrument that utilizes dual laser pumps to evaluate the thermal properties of materials, requiring specific features such as precise voltage outputs, modulation bandwidth, and high transmission efficiency. NIST is currently soliciting information from potential vendors who can meet these specifications, with an emphasis on product performance, customization options, and included services like installation and training; however, this notice serves solely for market research and does not guarantee a solicitation or contract award. Interested parties may contact Elizabeth Timberlake at elizabeth.timberlake@nist.gov or Donald Collie at donald.collie@nist.gov for further information.
