Rhea Series

Model : Rhea Series

Description :

Admesy’s Rhea is the new flexible platform in configurable spectral measurement demands within the range between 200 and 1100nm. Various choices in slit size, gratings and sensors allow you to build the perfect spectral measurement solution for your specific high-end measurement application or OEM integration. The Rhea series is available in a variety of optical systems: 5, 10 or 20mm collimating lenses, cosine corrector and fibre connectors. This flexibility makes the Rhea the ultimate high-end spectroradiometer for OEM integration, display, lighting and appearance measurements in both laboratory and production settings.
