Explore optical design, from connected components to 3D assemblies. Study rays, fibers, spectra, and wave fields with clearly defined inputs and model limits.
Let light shape your ideas.
Cosmic Titan is a Mac workspace for optical learning, teaching and research exploration. Combine lenses, mirrors, fibers, beam splitters, filters and detectors to investigate how design choices affect optical results.
Build optical systems
• Organize paths with draggable nodes and optical port connections.
• Adjust component positions and orientations in a 3D assembly view, with alignment, locking and replacement tools.
• Save projects, custom components and reusable subassemblies.
Explore propagation
• Investigate spherical and aspherical prescriptions, Snell ray tracing, and model-specific spot, wavefront and diffraction analyses.
• Use virtual observation planes to inspect geometric ray cross sections and power within an assembly.
• Compare settings with cross-dispersed spectrometer, Lyot coronagraph, detector-readout and parameter-scan tools.
• Explore ABCD networks, non-sequential ghosts and 2D angular-spectrum propagation within supported models.
Study fibers and photonics
• Explore scalar fiber modes, two-mode long-period fiber grating coupling and scalar BPM in preset taper structures.
• Calculate ideal AWG port spectra and export TE/TM block complex scattering matrices.
• Explore hexagonal IFU geometry, or import external calibration data for joint spectral extraction and cube reconstruction.
Keep the assumptions visible
• Consult model scope and assumptions, with energy accounting and numerical checks in supported modules.
• Export supported results as CSV, JSON or FITS for further analysis.
• Run core calculations locally, without creating an account.
The app includes geometric, scalar and idealized research models. Solver coverage varies by module, and some experiments operate independently of the assembly path. It does not provide comprehensive full-vector electromagnetics, complete non-sequential stray-light analysis or manufacturing-grade instrument validation. Interpret results using each module's documentation and independent validation.
Requires macOS 14 or later. Available in Simplified Chinese and English. Custom names and imported material retain their original language.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
1. Evaluate received-power uniformity, coefficient of variation, weakest cells, and cell deviations.
2. Inspect a cell crosstalk matrix with exclusive nearest-receiver assignment and full CSV export.
3. Scan 11 receiver radii to compare own-cell capture, crosstalk, and unassigned power.
4. Explore a 7×7 receiver-alignment map against a capture threshold.
5. Rank candidates by capture or uniformity and compare nondominated trade-offs within the finite scan.
6. Compare nine incidence angles within the thin-phase model.
7. Evaluate 12 manufacturing-variation samples with position, dual-axis focal-length errors, and repeatable seeds.
8. Budget detector-channel SNR using responsivity, dark current, bandwidth, and input current noise.
9. Compare exposure-averaged scrambling contrast across five initial-phase seeds.
10. Compare individual cells against a baseline, matching identities and identifying added or removed cells.
Also includes freeform microlens shapes, aperture/focus/layout editing, array assembly and optical-path insertion, per-cell spots, finer-sampling comparisons, alignment sensitivity, and the fiber-scrambling lab.
Retains the desktop workspace and navigation, with expanded collapsible analysis and bilingual guidance. Refined keyboard deletion and undo. The launch screen waits for Enter Workspace instead of an automatic countdown.
