When to review machine vision lenses.
The Machine Vision Lenses route fits precision measurement, part edge inspection, gauge-style measurement projects. Confirm object size and sensor size together.
Product route
Machine Vision Lenses
FA lenses, C-mount lenses, line-scan lenses, large-format lenses, low-distortion lenses, telecentric lenses and custom optics for inspection cells.
The project needs stable FOV, edge clarity, low distortion or repeatable measurementCalculate sensor size, object size, WD, focal length, pixel size and tolerance firstStandard lens for general inspection
Confirm these before model selection.
FA / line scan, Telecentric optics, Custom lens route are only the starting point. Also confirm field of view, working distance, line speed, interface, trigger timing and mounting limits.
Send evidence before asking for a part number.
Share sample images, good and bad parts, current reference model, target defect, tolerance, production speed and available fixture space.
Use these limits before locking a model.
- Do not lock a model before sample images, line speed and target tolerance are available.
- Do not treat the component as a standalone purchase when lighting, optics, fixture or trigger constraints are still unknown.
- Do not assume a reference brand or catalog model proves production-line acceptance.
Send route evidence before asking for a final part number.
- Part photos or short line video
- Good and bad sample examples
- Target feature size or tolerance
- Field of view and working distance
- Line speed, trigger and interface needs
When this route is a good fit
Machine vision lens choice starts from sensor size, FOV, working distance and distortion; Deyi reviews C-mount, line-scan, low-distortion and telecentric routes.
Use this route when the project matches these constraints.
- Use when
- The project needs stable FOV, edge clarity, low distortion or repeatable measurement.
- Core numbers
- Calculate sensor size, object size, WD, focal length, pixel size and tolerance first.
- Route split
- Standard lens for general inspection; telecentric or low-distortion route for measurement.
Do not quote this route before these checks are clear.
- Do not select focal length without object size and sensor size.
- Do not use regular lenses for tight measurement if perspective error changes the result.
- Do not ignore lighting geometry because lens choice can block usable light angles.

How buyers should compare this route
Build the product route around the inspection target, not the catalog model.
Use machine vision lenses when the inspection evidence matches the route.
Machine Vision Lenses should be evaluated when the project is tied to precision measurement, part edge inspection, gauge-style measurement. A useful review starts from the part behavior, target feature, motion condition and current failure mode, then maps those limits to the right component family instead of forcing one catalog model.
- Precision measurement
- Part edge inspection
- Gauge-style measurement
Compare constraints, not only specifications.
Use machine vision lenses selection as a system decision: lens, lighting, fixture, trigger, interface and software all affect repeatability. The safest shortlist is created only after sample images, line speed and output constraints are reviewed together.
- Confirm object size and sensor size together.
- Use telecentric optics when perspective error is unacceptable.
- Reserve enough working distance for fixture and lighting.
What engineering should confirm first
Four checks before locking the machine vision lenses route.
This workflow keeps the RFQ focused on the real inspection constraint and reduces the risk of buying a component that works on paper but fails under production lighting, motion or fixture variation.
- Define the inspection target State the defect, code, edge, height, presence check or measurement result that must be accepted or rejected.
- Lock optical and mechanical constraints Confirm field of view, working distance, mounting space, part motion, fixture stability and available light geometry.
- Match the component route Review machine vision lenses with related lenses, lighting, controllers, I/O and software rather than selecting one part number in isolation.
- Validate with samples Use good parts, bad parts and edge-case samples to confirm contrast, repeatability, read rate or measurement stability before purchase.

Common use cases
Common reasons product selection goes wrong.
- Choosing by resolution, catalog size or brand reference before defining the inspection target.
- Ignoring lighting, lens, fixture or trigger limits that decide whether the component can repeat on the production line.
- Requesting a quote without good/bad sample images, line speed, target tolerance or the current failure mode.

Request engineering RFQProduct FAQ
Common questions before selecting machine vision lenses.
How do I confirm whether machine vision lenses fit my project?
Start with the inspection goal, field of view, working distance, line speed and target tolerance. Then match machine vision lenses with lens, lighting, mounting and I/O requirements instead of choosing by part number alone.
What information improves machine vision lenses selection accuracy?
Send good and bad sample images, target feature size, field of view, working distance, speed, trigger method, interface requirement and any current reference model. That lets engineering confirm whether machine vision lens is the right route or whether another product family is safer.
When should I avoid selecting machine vision lenses by catalog specs only?
Avoid catalog-only selection when the part is reflective, moving quickly, tolerance-sensitive, space-limited or already failing under manual inspection. In those cases, lighting, lens, fixture and software behavior often matter as much as the component specification.
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.
