OPTICAL DEMO
Simulate your camera and check the optical setup before mounting anything
Adjust sensor, focal length, working distance and lighting and check the field of view and resolution of your machine vision system.
Validate before you build. Decide before you buy.
Simulate cameras, optics and lighting before manufacturing mounts, buying hardware or running physical tests on the plant floor.
Traditional approach
- Temporary setups and blind physical tests
- Mounts at the wrong distance, unexpected shadows and glare
- Glare and lack of contrast discovered on the plant floor
- 2D drawings and dry tables
vs
3D simulator + Rely
- Optical validation in minutes from your browser
- WD, FOV and resolution calculated before manufacturing
- Test lights and angles in 3D before buying spotlights
- Visual demo + clear path to inspection with Rely
CAPABILITIES
Everything you can validate with a 3D machine vision simulator
Check field of view, working distance, resolution, lighting and part position before taking your system into production.
Live resolution and PPM
Calculate pixels per millimetre and validate whether you can resolve 0.1 mm defects with a clear threshold (≥ 10 px/mm).
Realistic camera view
See what the sensor will see on the part while you adjust optics and distance.
Industrial lighting
In the full simulator, position lights (ring, bar, panel…) and anticipate glare before buying spotlights.
CAD parts in the scene
Load 3D models (GLB/GLTF; STEP via conversion) or use real-scale sample geometries.
Bridge to Rely
Once the optics are right, the next step is to deploy AI inspection on the Rely platform.
From optical simulator to real-time quality control
Sightline validates camera, lens and lights. Rely inspects in production with AI: defects, assembly, welding and deviations at line speed.
how it works
Design and validate your vision system before building it. Rely takes that vision into production to automate quality control with AI.
Check whether your vision setup resolves the defect you care about before requesting a quote or manufacturing mounts.
WHO IT'S FOR
Designed for those who can't afford mistakes during commissioning
Three profiles, one goal: certainty before buying or building.
Vision integrators
Close more projects with zero-cost visual PoCs. Prove feasibility before buying hardware and connect with Rely.
Mechanical and CAD engineers
Get the WD and mounting dimensions before modelling the cell in SolidWorks, Inventor or AutoCAD.
OEMs and quality (QA)
Validate whether an existing line can inspect a new part format without redesigning the whole structure.
One System · Total Control
Everything that Rely can control in this process.
Rely inspects 100% of every product in real time, ensuring that no contaminants make it past quality control.
Unpredictable contaminants.
Originating from pallets, crates, or transport equipment.
Generated during handling or cleaning processes.
Frequently asked questions
Yes. You can use it from your browser without downloading software or paying for a licence. It lets you validate FOV, working distance and resolution before moving to the RelyQA platform.
Manufacturer calculators are usually 2D tables or tools locked to their own brand. Sightline is a web-based 3D environment where you upload your part, adjust optics and lighting and prepare the jump to RelyQA in a vendor-agnostic way.
We relate sensor size, focal length and available space. In the demo and in the simulator you can see the viewing cone and the metrics (FOV, PPM) while you move the part or change parameters.
In the full simulator you can position industrial lights and check the result in the camera view. The micro-demo on this page focuses on optics (sensor, focal length, WD and PPM).
You get the required working distance and resolution before manufacturing mounts. Less mechanical rework and stronger proposals for the customer.
No. Sightline is the 3D optical design simulator. RelyQA is the vision and AI inspection platform for production. They complement each other: you design in Sightline and deploy in RelyQA.
