Product Introduction This integrating sphere can be used with other optical accessories to measure the absorption of water bodies, such as river water, seawater, groundwater, etc. One end of the integrating sphere is connected to the light source, and the other end is connected to the detector. The original water sample is placed inside the cavity. When the cavity is filled with water sample, the incident light is absorbed by the water sample inside the cavity and transmitted to the exit detection port, which can avoid the light scattering interference of particles in the water. The integrating sphere is made of high-quality PTFE material, with a reflectivity of up to 99%. The light source is transformed into uniform light output through countless integrals inside the cavity. The light field inside the sphere cavity is evenly distributed, and the sensitivity is improved through a considerable optical path (up to several meters).
