About this opportunity
The US Geological Survey is conducting market research to identify qualified suppliers of a Silicon Audio Low-Noise Optical Seismic Sensor (Model 203-60) and requests product data sheets by June 16, 2026 at 1500 PST. This sources sought announcement is not a binding procurement and carries no commitment to award.
The sensor is a scientific-grade borehole instrument integrating optical technology for geophysical applications. Key specifications include a passband of 0.005–1500 Hz, ultra-low noise ranging from 0.5 ng/Hz at 10 Hz to 10 ng/Hz at 0.01 Hz, dynamic range of 172 dB at 1 Hz, sensitivity of 60 V/g, and clip level of 0.5 g peak. The sensor delivers shock tolerance exceeding 1500 g, tilt tolerance of 15 degrees (up to 180 degrees available), operates across –35°C to +75°C, and consumes 150 mW for the 3-axis configuration. The borehole package measures 2.0 inches diameter by 14.5 inches length, weighs 1 kg, and requires 6–25 V DC supply voltage with distortion less than 0.03% at 12 Hz. No mass lock is required for transport.
Responses must be submitted via email to yangzhi_deng@ios.doi.gov as product data sheets detailing compliance with attached technical specifications. Hardcopy and web-portal submissions will not be accepted. The applicable NAICS code is 334513 (size standard 750) and PSC code is 6655. All responsible sources may respond; no set-aside applies.
