OptiCoat Designer
The first web-based thin-film optical coating designer. Design, simulate, and optimize multi-layer coatings with real-time calculations — all from your browser. No installation required.
The Problem
Optical coating design software has been trapped on Windows desktops with perpetual licenses costing $1,800–$8,000. Teams are stuck with outdated interfaces, single-machine installs, and no collaboration.
The Solution
OptiCoat Designer brings professional optical coating design to the cloud. Access your designs from anywhere, collaborate with your team, and pay only for what you need — starting free.
Powerful Features
Everything you need to design, simulate, and optimize thin-film optical coatings.
Transfer Matrix Simulation
Real-time reflectivity, transmission, and absorption calculations using rigorous transfer matrix methods with Sellmeier and Cauchy dispersion models.
Color Science
CIE 1931 color matching with D65, D50, A, F2, and F11 illuminants. Visualize coating colors across angles from 0° to 60°.
Design Optimizer
3-stage optimization with random search and refinement. Set reflectivity targets, reverse engineer from CSV data, or target specific colors.
Recipe Tracking
Track coating runs across multiple machines. Compare results, analyze trends, and monitor tolerance bands with design overlays.
Yield Analysis
Monte Carlo simulation for yield prediction. Analyze layer sensitivity, IAD adjustments, and color variance across substrates.
Advanced Visualization
Admittance loci, E-field distribution, and phase shift diagrams. Support for s-polarization, p-polarization, and unpolarized light.
10+ Material Database
Pre-loaded dispersion data for SiO₂, TiO₂, Al₂O₃, ZrO₂, Ta₂O₅, Nb₂O₅, HfO₂, MgF₂, Y₂O₃, and SiO — plus custom materials.
Cloud-Based
No installation. Access from any browser, any device. Save designs to the cloud and pick up where you left off.
Simple, Transparent Pricing
Start free. Upgrade as your needs grow. No hidden fees.
