What engineers should confirm before quoting.
- Confirm object size and sensor size together.
- Use telecentric optics when perspective error is unacceptable.
- Reserve enough working distance for fixture and lighting.

Common questions before selecting telecentric lenses.
How do I confirm whether telecentric lenses fit my project?
Start with the inspection goal, field of view, working distance, line speed and target tolerance. Then match telecentric lenses with lens, lighting, mounting and I/O requirements instead of choosing by part number alone.
What information should I send before requesting a machine vision quote?
Send part photos or drawings, target defect or measurement goal, field of view, working distance, line speed, accuracy target, lighting limits and any current camera, lens, light, barcode reader or competitor model.
Do I need a 2D or 3D machine vision system?
Use 2D when contrast, edges, labels or position are enough to judge the part. Use 3D when height, profile, gap, volume, weld shape or surface geometry decides pass or fail.
How should I choose machine vision lighting?
Start from the defect and material surface instead of the camera model. Backlight helps edge measurement, coaxial and dome lighting help reflective surfaces, and bar or ring lighting often works for general presence and defect checks.
Can Deyi Vision support projects that reference Keyence, Cognex or other brand routes?
Deyi Vision is not affiliated with those brands. As a factory-direct machine vision source, we can map the inspection goal, model reference and production route to a component-level camera, lens, light, reader or smart-camera selection.
