Abstract
Evaluate and compare the color reproducing ability of the new Hydro Products 400 watt dysprosium-thallium quartz iodide lamp, (D.T.I.) and the standard 750 watt E.G. & G. quartz iodide lamp which has been used on the D.S.R.V. ALVIN. Also, determine, whether the flat white parabolic reflector used by Hydro Products is an improvement over the silvered conical reflector which has been used on Alvin.
