Metalens & Diffractive Lens Designer New
Go/no-go scoping for metalenses, kinoforms and N-level DOEs: exact non-paraxial zone radii and local period, sinc² quantization efficiency, first-cut TiO₂ / a-Si / GaN nanopillar diameters, chromatic Strehl bandwidth, lithography fab pass/fail and the Presutti–Monticone achromatic bound. Zone/pillar CSV for GDS layout.
AR Waveguide k-space Designer New
Lay out a diffractive exit-pupil-expander combiner directly in normalized k-space: grating periods and orientations under the Levola ΣK = 0 closure, the per-colour TIR annulus, max field of view vs substrate index, single- vs multi-plate RGB verdicts, TIR bounce spacing and pupil replication. HoloLens, Magic Leap 2, Meta Orion (SiC) and Snap Specs presets.
Microring Resonator & WDM Filter Designer New
Closed-form ring design from the Yariv–Bogaerts transfer functions: FSR, loaded / intrinsic / coupling Q, finesse, extinction, critical coupling, all-pass and add-drop spectra, thermal-tuning power and N-channel DWDM plans. Runs in reverse too — enter a measured FSR, FWHM and ER to back out a, κ² and the Q budget, with the under/overcoupled ambiguity shown as both branches.
Space Laser Comm Link Budget Designer New
Full optical link budget for LEO/GEO downlinks, inter-satellite links and terrestrial FSO: a dB waterfall from Gaussian TX gain through statistical pointing, free-space and elevation-scaled atmospheric loss to photons-per-bit sensitivity, with HV5/7 turbulence giving Fried r₀, Rytov variance, aperture averaging and a lognormal fade margin. Reproduces the flight-measured DLR OSIRISv1 budget.
Datacenter Optical Link Budget Analyzer New
IEEE 802.3-style optical power budgets for datacenter links from 100G to 1.6T: NRZ/PAM4 presets, OMA / ER and TDECQ allocations, G.652 λ₀-corner chromatic-dispersion penalties, MMF Gaussian-ISI reach, a per-lane margin waterfall with a binding-constraint reach solver, and a DSP / LPO / CPO pJ/bit panel. CSV export of the budget table.
Zemax File Analyzer
Drop in a sequential .zmx file: instant prescription table, EFL / BFL / f-number from a real paraxial trace, ray-traced 2D layout and design warnings. Nothing is uploaded — parsing runs in your browser.
Sequential Ray Tracer
Exact skew ray tracing through multi-surface conic systems. Lens layout, transverse ray-fan plots, RMS spot diagrams, EFL / BFL / f-number — a Zemax-style sanity checker in the browser.
Waveguide Mode Solver
Analytic TE/TM modes of the asymmetric slab: effective indices, single-mode window, confinement, cutoffs, live field profiles and n_eff-vs-thickness dispersion — with SOI and SiN presets.
Gaussian Beam Propagator
Complex-q / ABCD propagation of laser beams through multi-lens trains. Beam caustic plot, intermediate waists, Rayleigh ranges, far-field divergence, and M² handling.
Diffraction MTF Calculator
Physical-optics MTF from pupil autocorrelation: central obscuration, defocus, spherical aberration and astigmatism, with detector Nyquist overlay and through-focus analysis.
Zernike Wavefront & PSF
Synthesize wavefronts from Noll-indexed Zernike terms, get P–V, RMS and Strehl, and compute the real diffraction PSF by FFT — with wavefront and PSF maps side by side.
Machine Vision Imaging Calculator
Full imaging budget for camera + lens selection: FOV, magnification, depth of field, diffraction vs pixel-limited resolution, Nyquist, motion blur — with standard sensor presets.
Wedge, Window & Tilt Calculator
Exact wedge-prism deviation, tilted-window beam displacement, and the focus shift + astigmatism a window adds to a converging beam — the alignment engineer's pocket reference.
Grating Spectrometer Designer
First-order spectrometer layout from the grating equation: diffraction geometry, angular and linear dispersion, resolving power, pixel bandpass, free spectral range and detector coverage.
Fiber Coupling Calculator
Single-mode fiber physics: V-number, cutoff, Marcuse mode-field diameter, and Gaussian mode-overlap coupling efficiency with lateral, angular and axial misalignment sensitivity curves.
Aspheric Surface Analyzer
Even-asphere sag, slope and local curvature, best-fit-sphere computation, aspheric departure and slope-departure for metrology planning, plus exportable sag tables for manufacturing.
Achromatic Doublet Designer
Automated cemented-achromat synthesis: Abbe power split for your glass pair, then shape optimization by exact ray tracing to minimize spherical aberration. Radii, layout, LSA and chromatic focal shift.
