Led lighting for Machine Vision
Lighting is a crucial component of any machine vision system: choosing an illuminator of a given color or geometry can effectively reveal or mask the characteristics of an object, thus enabling the software to process the resulting image properly.
Opto Engineering machine vision illuminators are designed to meet the ever-more stringent requirements of industrial automation.
Opto Engineering offers a wide range of industrial LED illuminators, designed to illuminate uniformly with direct or indirect light, with diffused or collimated light, in various wavelengths and operating modes (continuous/strobed/boosted). We offer various illumination geometries including collimated telecentric illuminators, pattern projectors, backlights, ring light units, coaxial, dome, bar and spot illuminators.
Collimated telecentric illuminators
Opto Engineering has also applied telecentric technology to its LED illuminators: our collimated illuminators, combined with our telecentric lenses, offer exceptional performance in optical measurement applications, with increased depth of field and minimal undesired reflections. Some of our illuminators are designed for use with our lenses, generating lighting optimized for specific fields of view and, in some models, also install directly to their compatible lenses.
LED pattern projectors
Opto Engineering LED pattern projectors are designed for use in 3D reconstruction, profile measurement, stereo vision, alignment, flatness control and robot guidance for pick&place applications. Opto Engineering offers a complete range with various power ratings, operating modes (continuous/strobed) and wavelengths, as well as special models with a tilting mechanism that enables uniform projection even on inclined surfaces. Our LED projectors are compatible with any C-mount lens, can project areas of various sizes, feature a vast range of interchangeable patterns and, in contrast with laser projectors, provide clearer edges and more uniform illumination (no speckle effect).
Applications
- Metrology: Collimated telecentric illuminators provide parallel and uniform light. When paired with telecentric lenses, this configuration enables accurate non‑contact inline measurement of turned parts, profiles and mechanical components.
- Pharma, Medical & Personal Care: Ring lights provide uniform illumination when combined with 360° view lenses for cap and closure inspection. Backlights ensure sharp contrast for fill‑level verification. Dome illuminators enable diffuse lighting for reliable capsule surface inspection.
- Automotive & Batteries: High‑speed strobed illuminators provide intense, synchronized lighting for injector nozzle, rotor/stator and fastener inspection. UV illumination enables clear visualization of fluorescent defect markings for reliable quality control.
- Electronics & Semiconductors: coaxial lights provide uniform, glare‑free illumination for solder joint and PCB pattern inspection. Dome or ring lights deliver diffuse lighting to ensure reliable component presence/absence detection.
- Food & Beverage: Backlights and ring lights provide uniform illumination for fill‑level, closure integrity and chromatic quality checks. Optimized lighting conditions enable high‑contrast OCR on colored packaging.
- Web & surface inspection: LTLNC, LTLNM and LTLNE high‑power line lights deliver intense, uniform illumination for defect detection on paper, film and textiles. Optimized line lighting supports reliable inspection of battery coatings.
- 3D inspection: pattern projectors deliver structured light for surface reconstruction and flatness verification. Structured illumination enables precise robot pick‑and‑place guidance.
