In-Situ Spectrophotometer / Absorption Meter
a-Sphere is simply the best way to measure the optical absorption of any liquid, in the ocean or in the lab. a-Sphere redefines the state of the art, with more than 10 times greater spectral resolution than the nearest "high-resolution" alternative—and more spectral range—all without moving parts. Its innovative integrating sphere design provides high sensitivity with no scattering error, yet is impervious to contamination and easy to maintain.
