Stemmer Imaging has introduced the Metawhite Exolight range of light-emitting diodes (LEDs) as an alternative to fluorescent lighting for machine vision.

Patented and patent-pending LED technology and advanced optics create an even and diffused cool white illumination three times brighter than fluorescent sources over a longer working distance.

This makes them suitable for low-cost machine vision lighting, including robot-mounted applications.

Available in 8in, 14in, 24in and 48in lengths, the Exolight range of LEDs can be used as direct replacements for traditional fluorescent light fittings.

They are available in a number of wavelength ranges covering white, red, green, blue, amber, red-green-blue (RGB), ultraviolet (UV) and infrared (IR).

They feature anisotropic plastic micro-lens diffusers to create a highly diffused light from multiple point source emitters, unlike traditional diffusers that tend to reduce LED intensity.

The resultant output mimics that of fluorescent emitters, but with more power and a greater stability, combined with the long LED lifetime and a low cost of ownership.

Since the Exolight output is free from the typical hot spots inherent in other LEDs and does not suffer from the multiple shadows normally associated with high-brightness LEDs, these light sources provide intense yet well-spread area illumination.

Exolight provides an end-to-end light emission with optional intensity control that fluorescent fixtures cannot match owing to their need for complex ballast and starter circuitry.

With no glass or mercury content and no EMI and RFI, these lights are environmentally friendly.

Fully CE rated and maintenance free, Exolights have a typical lifetime up to 100,000 hours.

STEMMER IMAGING is Europe’s largest imaging technology provider with headquarters in Germany and subsidiaries in the United Kingdom, France and Switzerland.

Image processing or Machine Vision is used in many different application areas – such as industrial automation, medical imaging, security and traffic technology – as a powerful and cost effective way of implementing automatic quality assurance. Even at high speeds and with stringent accuracy requirements, image processing allows 100% monitoring and thus strengthens the competitive edge of those companies using it.

STEMMER IMAGING customers have access to a wide variety of imaging products from the worlds leading manufacturers. These manufacturers represent the cutting edge of vision technology which is something that is unique in Europe. STEMMER IMAGING are the developers of the world’s leading image processing software platform, Common Vision Blox, and as a manufacturer of customer-specific products, we have a full range of in-house expertise to draw on, allowing us to supply the best possible service to our customers when choosing an imaging solution. STEMMER IMAGING does not produce turn-key solutions – instead, using our close partnerships with a large number of experienced system integrators, we can provide expert technical know-how for the planning, integration and realisation of complete solutions.
