Photonics Calculators

Starting on step 3 is where the tools can be chained together to perform a scenario analysis. This is primarily done by copying the output values of one tool into the clipboard for input values in the next tool. An automated overall tool to do this seamlessly is in development and will be posted in the GitHub. All sliders can be over-ridden by the text at the right end of the slider.
