Live Ray Trace & Diffraction Field (2D Optics Bench)
Drag Occulter / Align Axis
Light Path: Photosphere → Occulter (C1) → Field Lens → Lyot Stop → Focal Detector
Occulter Aligned
Controls solar disc alignment and Fresnel edge diffraction.
Primary lens focal length determining coronal scale factor.
Internal light traps to diminish internal reflection stray light.
Controls photon noise integration and CME plasma stream SNR.
Narrow passband suppresses sky continuum noise.

Optical Alignment: Padua coronagraph occulting disc disk size (24.5mm) blocks direct sunlight. 4 baffle knife-edges eliminate edge diffraction rings, driving stray sunlight down to -58.4 dB. CME plasma jets in Fe XIV (530.3nm) achieve strong HIGH signal contrast.
Generates spectral calibration curve & spatial radial intensity profile dataset for astrophysics analysis.
