Underwater Spectroradiometer Accessories

Underwater spectroradiometer accessories from SVC make it possible to capture accurate, repeatable spectral data below the surface. Rugged diver-operated housings deliver precise measurements in marine and freshwater environments, supporting studies in water quality, habitat monitoring, and environmental change detection.

From Fiber Optics to Rugged Enclosures
Early underwater measurements used fiber light guides to transmit reflected energy to instruments above the surface. These fibers were expensive, fragile, and often failed. Coordination between the diver and surface operator also made accurate targeting nearly impossible. These challenges drove the development of durable underwater enclosures.

A History of Aquatic Research
Working alongside marine scientists and limnologists, Spectra Vista has expanded the ability to measure the spectral reflectance of natural and manmade materials below the waterline.

Proven Instruments

• GER 1500: Long regarded as the workhorse for underwater applications, effective in the VNIR spectral region where sunlight penetrates beneath the surface.

• SVC HR-512i: Outfitted with an external enclosure, it continues this legacy of reliable underwater performance.

The Latest Generation
Building on decades of experience, Spectra Vista now offers the newest underwater enclosure for its i-Series spectroradiometers. Designed for reliability and ease of use, it gives today’s researchers the tools they need to collect high-quality aquatic data with confidence.
