Colored filter glasses: an intercomparison of glasses made by different manufacturers.
Specifications of about eight-hundred colored glasses made by thirteen manufacturers are examined and intercompared. The internal spectral transmittances of typical glasses are plotted in a series of forty-four diagrams. A log (internal density) vs wavelength representation is used. Curves with similar characteristics are grouped together in the same diagram. The internal spectral transmittances for a number of different thicknesses of each glass type can be read directly from the diagram. The curves are identified in a table, which lists the equivalent thicknesses of glasses yielding approximately the same transmittance. Such information facilitates the choice of filter components of reasonable thickness.
