Interactive Model (Webapp)¶
A live, physics-based model of the grism spectrograph running entirely in your browser: field position and wavelength in, detector centroid out. Drag the sliders to see how each physical parameter — tilt, groove density, prism angle, focal lengths — reshapes the light path and the resulting spectral trace.
It's a self-contained reimplementation of the same optics
dispcraft.optics and dispcraft.calibration describe (no server, no data
file dependency) — built for outreach and for building intuition before
diving into the notebooks or the API.
