SIEMENS NERLITE LED Lighting for Vison Inspection Applications Siemens Nerlite The Science of NERLITE As the leading innovator in the field of precise illumination for machine vision, Siemens has mastered the highly complex nature of machine vision illumination. Cameras see light as it is reflected from an object. Light is reflected differently from a metal ball than from a flat white label or a printed circuit board. The purpose of machine vision illumination is to control how the object appears to the camera. With these differences in mind, we study the geometric patterns of the light reflected from the part and designs lighting systems to control glare and reflection. Developed with a sophisticated knowledge of ray tracing and uniform lighting, NERLITEs enable vision engineers to work with clearer and crisper images. To meet the varied needs of machine vision applications, Siemens has created three distinct lines, with increasing levels of sophistication: DOAL, SCDI, and CDI

NERLITE Technology NER Machine Vision Lighting products are manufactured under the brand name of NERLITE. NERLITE is widely recognized around the globe as the "standard" for machine vision illumination and machine vision imaging. Our products are designed with practical, cost-effective technologies. The NERLITE brand encompasses a wide selection of products, including: Area Arrays, Spot Lights, Linear Arrays (Line Lights), Ring Lights, or Dome Illuminators Backlight and Dark-Field Illuminators DOAL® & COAL – Diffuse On-Axis Light® & Collimated On-Axis Coaxial Lights SCDI® – Square Continuous Diffuse Illuminator CDI® – “Cloudy Day®" Continuous Diffuse Illuminator MAXlite–Multi-Axis Light and also NERLITE designed custom illuminators for OEMs Lighting Techniques NERLITE machine vision lighting products are designed to control "light delivery" to the CCD array (camera.) There are many lighting techniques to choose from including: ring lights, dark-field lights, backlights, coaxial (on axis) lights, continuous diffuse lights, dome lights, area arrays, line lights and spot lights. For a starting point in choosing the best lighting technique for your machine vision imaging application, see our light selection chart. Care & Maintenance NERLITE Machine Vision Illumination Products are engineered and manufactured to high quality standards to meet the needs of industrial applications. By following the practices outlined in our Care and Maintenance sheet, your standard NERLITE products will meet warranty qualification requirements and provide years of trouble-free service. Markets & Applications NERLITE products can be found in the majority of applications that involve machine vision imaging. They are also found in automated identification applications, particularly those using 2-D symbologies (Data Matrix, PDF-417, Maxicode, etc.) with direct parts marking. Markets served with NERLITE products include: electronics, semiconductor, automotive, pharmaceutical, packaging, mail-sorting, warehousing and general manufacturing. Light Sources NERLITE machine vision lighting products use a variety of sources to complement our lighting techniques. In addition to our core LED (light emitting diode) technology, the sources include fiber optic, xenon strobe, CCFL (cold cathode fluorescent lamp), fluorescent, halogen, electro-luminescent panels and metal halide.
