ABSTRACT:
A standard substance for optical calibration is produced by mixing a proportion of a scattering substance with a first silicone liquid. The optical properties of the first liquid are measured and a further amount of the first liquid is added to the original mixture to provide a desired optical property. Then, the mixture is further mixed with a second silicone liquid which initiates a curing process. The final mixture is poured into a transparent vessel for curing. The transparent vessel, with the cured final mixture inside, is useful as a standard substance for calibration of an optical equipment. A technique for calculating the proportions of the mixtures is disclosed.
