Integrating Sphere - Question and Answer #4

The contract seeks the procurement of two identical integrating spheres equipped with all necessary supporting components to enable traceable spectroradiometric measurements across the visible-near infrared to shortwave infrared spectrum. The systems must deliver an absolute uniform spectral radiance output that is directly traceable to national metrology standards such as those maintained by NRC in Canada or NIST in the United States, ensuring calibration integrity and measurement accuracy under diverse environmental conditions. The equipment must be designed to easily adjust output levels to accommodate a wide range of operational scenarios including daylight, nighttime, cloud-covered, and full-sun exposure, reflecting the sensors' intended use in real-world remote sensing applications. The solicitation is issued by the National Research Council of Canada under solicitation number 26-58044 Q&A #4, with responses due by July 23, 2026, and inquiries should be directed to the contracting authority Shawn Doyle. While the NAICS code indicates classification under other electronic component manufacturing, no details regarding pricing, delivery schedules, inspection criteria, or contract clauses are available due to repeated system errors preventing access to critical sections of the solicitation documentation. The place of performance is listed as Canada, and no information is provided on packaging, marking, evaluation factors, representations, or special requirements.
