Low Distortion Lenses

A low distortion lens is a lens described by its low distortion behaviour: straight lines in a scene stay straighter in the picture than they would through a lens with more distortion. This page covers the Low Distortion Lens category as listed by Hangzhou Ai Ke Electronics Co., Ltd.

Distortion matters most where the shape of things in the picture is itself the information. If a buyer is measuring, inspecting or comparing shapes, a bent line in the image is not a cosmetic flaw but a wrong measurement. Where the picture is only watched for a general overview, distortion matters less, which is why this category deserves its own page rather than being folded into the general CCTV category.

What this category covers

This category covers low distortion lenses as a named category in the company's listed range. It does not state a distortion figure, a measurement method or a tolerance for any lens, because no such figure is published in the material used for this site. Any buyer who needs a distortion figure must ask for it for the exact lens concerned, and must ask how it was measured.

Low distortion is a property of a lens design, not a separate mount or a separate camera type. A low distortion lens may still belong to another family, such as a CCTV lens or an industrial lens, and the inquiry should therefore name both the distortion need and the camera family.

Where low distortion matters

Low distortion lenses are relevant to inspection and measurement work, where a camera checks the shape, position or size of an object, and to any application where straight edges, grids or outlines must be read faithfully. They are also relevant wherever a picture will be analysed rather than only watched, since analysis software reads the geometry of the image as data.

For general watching, where the question is only whether something is present or moving, a buyer may not need this category at all. Saying so plainly is part of the page's purpose: it prevents a buyer from paying for a property the job does not require.

What to confirm before ordering

Confirm what low distortion means for the exact lens offered, including how distortion is described and measured for that lens, and confirm that the description matches the buyer's application. Confirm the model, specifications, minimum order quantity, lead time and price for the quantity required, and confirm compatibility with the buyer's camera.

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

Frequently asked questions

Does low distortion mean no distortion?

No lens description on this site promises zero distortion. Low distortion is a relative description, and the exact behaviour must be confirmed for the lens offered.

Do I need a low distortion lens for general CCTV watching?

Not necessarily. It matters most where shape, measurement or image analysis is involved. For a general overview, describe the job and ask whether the property is needed.

Is a distortion figure published here?

No figure is published on this site. Ask for the figure and its measurement method for the exact lens concerned.
