Getting started
Install
How to install and use the three front ends: the desktop installer, the web version in your browser, and one-click MCP setup for your AI client.
Beta Guide
For testers: how to run the portable build, what to look at first, what is not done yet, and how to report problems.
Release Notes
What changed in each release: sign-in and trial, tier-gated features, new features, and numerical fixes that can change existing results.
Quickstart
Four ways in (desktop, command line, AI, Python): build a Cooke triplet, read the prescription and spot diagram, change one number.
Capabilities and Scope
What works today and what does not yet: surface types, materials, multi-configuration, analyses, optimization, tolerancing and interoperability.
Known Issues
Problems we already know about in the beta: what they affect, how to work around them, and where we are on each.
User guide
GUI Guide
The desktop app: 3D canvas, tables and text, command palette, change timeline, AI collaboration.
.lens Guide
Write a lens from scratch: system, surfaces, glass, solves, variables, multi-configuration.
Plotting Guide
Publication-quality figures: figure frame and evidence id, data tables, view options, export formats.
Report Material Pack
Export the figures, tables and numbers a report needs in one go, each with its evidence id; stale ones are flagged when the design changes.
Orchestration: Actions and Reports
Actions and reports: write a change such as swapping a glass as an action, and get a before/after comparison of optics, thermal effects, weight and materials with one command.
Merit Function and Optimization
Merit functions, the default merit function, local and global optimization, acceptance specs and verify.
Using LensBench from Python
Open a lens in Python / Jupyter, tune operands, pull analysis data, make figures.
AI-Native
Connect Claude, Cursor and other AI clients: setup, tools, safety boundaries, long-running jobs.
