Opto Engineering offers a wide range of macro lenses, designed for close working distance applications which demand very high precision and close to zero distortion.

Opto Engineering offers a vast range of precision telecentric and bi-telecentric lenses for the most diverse requirements of the market: models for high and low resolution area and line scan sensors in a variety of magnifications and working distances; classic, compact and flat lenses, along with standard and custom solutions. The range also includes special telecentric lenses: lenses with integrated liquid lenses, zoom lenses, optical benches and other special products. Opto Engineering 360° view lenses are unique designs that make it possible to inspect an entire product while reducing the number of components in the vision system. Thanks to their special optical design, just one camera is needed to simultaneously inspect multiple surfaces of an object: the bottom and internal surfaces, or the top and external surfaces. The family includes multi-view lenses which give a single image of the object containing a variety of points of view. Many of these 360° view lenses represent an innovative way of resolving vision applications, previously considered impossible, in a simple and effective way: they are used in numerous industries, from food & beverage to pharmaceutics and automotive. Some of these extraordinary optical innovations are the fruit of Opto Engineering’s R&D, have been patented internationally, received numerous awards, and constitute an extremely valuable resource for our clients.

Telecentric lenses are used in innumerable vision applications, and in particular they form the critical component of the optical system when precise measurement is required. Non-contact measurement applications demand the use of such lenses which, thanks to their low distortion, can eliminate perspective errors (parallax effect) due to imprecise positioning or objects with strongly 3D geometries.

This family includes: special remote controlled models with integrated liquid lenses for fast and precise focusing; lenses for SWIR and UV applications; lenses with Scheimpflug adjustment and variable magnification lenses.

Other features: DX decoding, XA-style lens protection, tripod socket. There was also a teleconverter and close-up lens available. Requires a PR-P2 6 volt lithium battery.

In machine vision applications, choosing the right lens is essential to obtaining high quality images suited to efficient and accurate processing. In many cases, the lens is the starting point for the construction of a machine vision system, although the result also depends on the resolution of the camera and the pixel size.

Using the IRI as a model, the roughness index was found by summing the vertical deviations of the surface profile for a given horizontal distance.
