Proportional Spectral Power Distribution (SPD)

This web-page is designed to display the proportional SPD values derived from normalised full SPD curves relative to a theoretical uniform light source. For more information relating to the graphing library used in this page see the moobargraph website. For more information about the project in general contact Joseph Padfield.

Displaying relative proportional SPDs for selected light sources:
