Abstract:

A submersible light transmissometer-nephelometer was designed and constructed for the purpose of measuring the beam attenuation and relative volume scattering coefficients at two fixed angles and at depths to 1000 meters. Flexibility, a major design criterion, makes it possible for the unit to be operated in a number of configurations. Addition of an internal battery supply, a filter wheel, light stops, a photomultiplier tube and amplifiers is possible. The NPS light transmissometer-nephelometer is not a single purpose instrument but has the capability to be utilized as a submersible optical bench, useful in the development of underwater optical instrumentation.
