I wanted an app that didn’t just tell me what orders were present and what angles they were at, I wanted to be able to more easily visualise them. I needed to be able to easily select the grating properties as well as the wavelength of light used, since for my application I was using several light sources all of different wavelengths.
Diffraction Grating Order Calculator. It’s on a separate page so that there’s more space available than in my main website’s layout.
The Raphael parts were fairly straight forward. The hardest bit was getting the HTML to play nice with all browsers. Time to start my next app now, I’m hooked! Email with any suggestions for others, be they educational, time saving or commercial, I’d be interested to hear.
