Lighting is critical in machine vision applications, as it allows vision cameras to “see” the part or mark. The better the lighting solution, the better your machine vision system will perform. Accurate, reliable and repeatable performance means greater productivity at a lower cost to you.
Microscan’s innovative NERLITE® lighting products enable machine vision and auto ID systems to perform reliably in thousands of applications worldwide. NERLITE is the longest-established brand of machine vision lighting, and has grown and been refi ned from our experience with hundreds of applications in dozens of industries. Ranging from simple solutions for common applications, to technically advanced confi gurations for challenges involving transparent, highly specular, round or irregularly shaped objects and surfaces, there is a NERLITE solution for your lighting problem.
HI-BRITE illuminators provide a high intensity output over a large area. Featuring IP67 industrial sealing and the brightest LEDs in their class, they include a built-in controller for a complete and easily integrated solution for rugged automation environments. Versatile 10° spot and 50° fl ood lens options allow them to be used at both near and far distances to accommodate a variety of applications.
An Area Array’s general purpose, unidirectional design (adjustable via mounting position) may be used for dark fi eld (creating shadows and specular refl ection) or bright fi eld lighting for diffused surfaces. As with other incident lighting choices, subtle adjustments to working distance and angle of light delivery can deliver good image contrast for minimal investment.
Bar lights use LED arrays in compact, linear units to provide economical illumination for a variety of applications. As with other incident lighting choices, subtle adjustments to working distance and angle of light delivery can deliver good image contrast for minimal investment.
Ring lights are a cost-effective, easily integrated solution for illuminating surfaces. Packaging and mounting advancements emphasize durability and versatility for any diffused surface lighting application. As with other incident lighting choices, subtle adjustments to working distance and angle of light delivery can deliver good image contrast for minimal investment.
Backlights provide sharp contrast to outline a part’s shape, minimize visibility of clear housings, and to view openings such as drilled holes. High intensity and uniformity are packed into a low-profile industrial package for optimal thermal management. Edge To Edge models can be easily combined to create larger illuminated areas.
Dome Illuminators are an economical source of diffused, uniform light. Their large, solid angle of illumination supports imaging of curved, shiny or bumpy surfaces. They are a cost-effective alternative to CDI illuminators for applications not requiring an on-axis lighting component.
- Illuminate diffused or specular, fl at or curved surfaces
- CD/DVD label inspection
- Inspection of surfaces for contaminants such as particles or residues
Dark field Illuminators provide effective low-angle lighting to targeted regions, and enhance the contrast of surface features such as laser embossed or engraved marks or surface defects. Dark field illuminators are particularly well suited for applications such as reading laser-etched symbologies, and inspecting surfaces with geometric contours.
DOAL illuminators provide the best contrast for images of features marked or embossed on a fl at specular surface with diffuse and uniform on-axis illumination. With the coaxial lighting approach, specular surfaces perpendicular to the camera appear bright, while surfaces which are marked or embossed absorb light and appear dark.
SCDI illuminators provide enhanced diffuse lighting performance. The patented design makes it ideal for inspecting moderately faceted and undulating reflective surfaces. SCDI illumination allows products to be inspected in the package and prevents non-uniform light reflections from causing a vision system to see defects where none exist.
CDI illuminators combine patented optics with precision integrating sphere technology to yield a self-contained continuous diffuse lighting environment. The advanced design provides extraordinary diffuse lighting performance for critical applications. They are ideal lights for inspecting highly faceted and undulating reflective surfaces, such as inspection of blister-packaged products.
