Machine Vision Lenses

Machine vision is the use of cameras to inspect, measure or guide a process: a camera watches a product, a part or a scene, and the picture is used to make a decision, whether by a person or by software. This page covers lenses for machine vision, as an application area. Availability of a suitable lens from Hangzhou Ai Ke Electronics Co., Ltd. is not established for any particular requirement; ask whether a suitable lens is available before ordering

A machine vision lens is judged by whether the picture gives the information the job needs. That is a stricter test than general watching, because a picture that looks fine to a person may still be wrong for measurement, and a picture that is fine for measurement may look odd to a person. The inquiry should therefore describe the decision the picture must support.

What machine vision use requires

Machine vision jobs include checking a product for defects, measuring a part, reading a mark or code, guiding a robot or a tool, and counting or sorting items. Each job asks a different question of the picture: shape, size, position, surface, colour or presence, and the lens must serve that question rather than a general idea of quality.

The machine vision camera lens guide on this site explains the camera side of the same choice, and the machine vision zoom page covers jobs where the view must change. The low distortion category is also relevant here, because measurement work is sensitive to distortion in the image.

Planning a machine vision view

Planning starts with the object and the decision: what is being looked at, how big it is in the picture, how it is lit, how fast it moves, and what counts as pass or fail. Those answers decide the lens far more than the camera brand or the general category, and an inquiry that omits them cannot be answered properly.

Consistency matters as much as sharpness. A machine vision setup is usually repeated many times, so the lens and lighting must give the same picture on every repetition. An inquiry should say how the setup will be repeated and what variation is acceptable.

What to confirm before ordering

Confirm the lens category and, where one is offered, the model that fits the buyer's machine vision camera and job. Confirm the specifications, minimum order quantity, lead time and price for the quantity required, and confirm compatibility with the camera and mounting arrangement, in writing, before ordering.

Documents should be confirmed at the same time. Certificates available upon request. No certificate detail is stated on this site.

Frequently asked questions

Is a machine vision lens a special product?

On this site it is an application description, not a separate model range. It describes lenses used for inspection, measurement and guidance jobs, drawn from the company's listed categories.

What makes machine vision different from CCTV watching?

The picture must support a decision, often a measurement, rather than only being watched. That stricter test shapes the lens choice.

Do I need a low distortion lens for machine vision?

It depends on the job. Where shape or measurement matters, read the low distortion page and ask whether the property is needed for your exact lens.
