3DOptix optical design and simulations

By 3DOptix

3DOptix brings cloud-based optical design and simulation into Claude. Describe the system you want and Claude builds it, runs a GPU ray trace, and reads the results back to you. WHAT YOU CAN DO • Build setups from scratch or from starter templates, in millimetres or inches. • Place and align optics, light sources and detectors by absolute pose, and reposition them without recomputing coordinates by hand. • Search the catalog of real, orderable components — lenses, mirrors, prisms, gratings, beam splitters, apertures, windows and filters — from manufacturers including Thorlabs and Edmund Optics, filtered by focal length, diameter, material, coating and substrate. • Add optomechanics: mounts, cages, posts and rails. • Run GPU ray-trace simulations and get a ray table back. • Analyse the result across the full wave-optics range: incoherent and coherent irradiance, coherent phase, Huygens and Fresnel diffraction propagation, PSF and MTF, polarised variants of each, and spectral collection — at a resolution you choose, then render the analysis as an image. • Optimise a layout against a figure of merit with explicit free variables and constraints. • Import existing designs — Zemax sequential files, and STEP/CAD geometry for custom parts. • Compute optical parameters directly: effective focal length, surface radii, centre thickness, refractive index at a wavelength, and material lookup by index. HOW IT CONNECTS Sign in with your 3DOptix account through OAuth. There is no API key to paste and nothing to configure by hand — Claude prompts you to authorise the connection on first use, and guides you through it if anything goes wrong. WHO IT IS FOR Optical, photonics and laser engineers who already work in 3DOptix, and anyone prototyping an optical layout who would rather describe it than click it together. REQUIREMENTS A 3DOptix account at 3doptix.com. New accounts get a fully functional trial; continued use needs a subscription. Simulations and analyses consume accou

3Min API

By Maverick Works

3Min API turns a plain-language description into a working REST API endpoint — no backend code, no server to run. Describe what you want to collect (inquiries, orders, signups) and an endpoint goes live. Define a JSON schema if you want field validation, or skip it to accept any payload. Every endpoint comes with full CRUD operations, webhook delivery to your own server, separate sandbox and production environments, searchable call logs, and usage statistics. With this connector you can: • Create, update, and deploy endpoints — one sentence is enough, and each new endpoint is automatically verified with a test call • Send real requests to your own endpoint (create, read, update, delete) to confirm it works before going live • Search everything you have received by keyword across the entire payload, or look up a single record • Track monthly and daily usage with success rates and response times • Issue scoped access keys for partners and control exactly which operations each one may perform • Export archived records in bulk • Generate ready-to-paste snippets that render an endpoint on a WordPress page Every action is scoped to your own account; other users' resources are never reachable. Sign-in uses OAuth, so no API keys are exchanged in conversation, and responses mask sensitive values such as access keys and collaborator email addresses — full values remain available only on the web dashboard. Deleting an endpoint, changing plans, and billing are handled on the web dashboard, not through this connector.

9pm

By ROOM 3D Communications S.A.

9pm is a deployment platform built for the agent era: apps go from a conversation to a live URL in seconds, with no CI pipeline or cloud console in between. This connector lets Claude manage and deploy your 9pm apps directly: - Create apps and list the ones you already have - Deploy static sites, uploading only the files that changed - Deploy container apps by pushing an image build - Track deployment status and fetch the public URL of any app A typical flow: ask Claude to build something, then say "deploy it". Claude creates the app, uploads the build, waits for the deployment to finish, and hands back a live 9pm.ai link you can open or share. Requires a 9pm account (sign up at https://9pm.ai). The connector authenticates with OAuth and only ever sees your own apps.
