Integrating Sphere

The National Research Council Canada (NRC) seeks to procure two identical integrating spheres with supporting components for traceable spectroradiometric measurements in the VISNIR to SWIR spectrum. The equipment must provide absolute uniformity spectral radiance output traceable to a national metrology standard (e.g., NRC or NIST). The system must allow easy variation of output to suit day/night/cloud/full sun conditions. This is a supply-only procurement with no specific qualifications mentioned beyond technical specifications.
