Machine Vision and Specialty Technical Lighting

For almost 15 years METAPHASE has been focused on developing products that harness "The Quality of Light" developing, manufacturing and marketing LED lighting solutions for the machine vision and inspection industries.

METAPHASE provides an ever broadening and expanding product line with over 1000 different specialty lights and power supplies. Today there are already thousands of installations around the world and nearly every day a new application can be added.

LED Line Lights

  • Web inspection
  • Geometry measurement of long objects
  • Direct position measurement
  • Printed Circuit Board inspection
  • Tube or bottle inspection

Todays line lights for imaging applications require ultra-high intensity with unprecedented uniformity. The line lights by METAPHASE feature ease of integration and an adjustable lens to emit a narrow beam of light, which can be focused from as close as 10mm to up to several meters away. Enhanced cooling options include either integrated fans or a new computer controlled micro-flow compressed air thermal control system.

Applications include front or back illumination for high speed scanning applications as e.g. for the web converting industry. Patent pending micro-lenses produce a homogeneous beam output in an uniform and powerful straight line. Solid state performance assures 75,000 hours lifetime. METAPHASE offers the largest selection of standard length line lights available from 2" to 120" in 5" increments. This allows you to buy just the right amount of light that you need, saving you costs without compromising performance.

The high intensity line lights are available in high power MetaBright and standard MetaLight series.

  • Critical dimension measurement as e.g. measuring the threads of a glass bottle
  • Servo positioning
  • Position measuring
  • Locating defects in flat objects
  • Packaging inspection
  • Components location verification
  • Backlighting for scanning applications

Backlights are commonly used for vision applications where a large field of view is required and the entire target is illuminated from the back side. When used alone or combined with front lightings the target will create a dark silhouette image against an uniform background, thus, providing a high contrast image and consistent edge definition of profile features. The backlights by METAPHASE are available in high power MetaBright, standard MetaLight and washdown MetaTight series.

  • Inspecting pharmaceutical blisters (form, fill and trim)
  • Control of cosmetics and makeup packaging equipment

Do you have an application requiring an all over even illumination especially where you need to remove shadows and reduce reflections on a shiny or polished surface?

METAPHASE Diffused Dome and Diffused Tube light illuminations provide an intense uniform light for inspecting objects with highly reflective, specular, round or uneven surfaces. These illuminators are durable and precisely formed to optical specifications from hydro formed aircraft grade aluminum and then painted inside and out for durability and optical purposes.

The dome lights provide a shadowless illumination and are very compact in size but big on output. According to optical engineers the dome light is arguably one the most perfect lights available because it mimics the effects of outdoor sunlight on an overcast day. The Diffused Tube Lights were invented to address the needs of lighting specular surfaced objects with high aspect ratio (wide or thin) profiles. The Diffused Dome and Tube Lights are available in high power MetaBright and standard MetaLight Series.

Ring Lights

  • Label identification
  • Direct part marking identification
  • Surface inspection
  • Illumination for microscopic stages
  • Solder pads inspection
  • Components identification
  • Inspecting features of molded parts
  • All applications where you need close-up, near-shadowless illumination with a single light source

With their familiar ring-shaped form, ring lights are probably one of the most recognizable types of close-up camera lighting available today. And it is no wonder as they are also the oldest... ring lights evolved from the familiar ring shaped task lamp magnifiers used by millions of line assembly workers; a legacy hearkening back to sometime after the invention of the first circular florescent lamps. METAPHASE LED ring lights on the other hand have been around almost since the invention of the first use of cameras for industry and are renown for their near shadowless illumination, intensity, power and 5x lifetime over fluorescents.

METAPHASE ring lights are specially designed to project an even 360 degree overlapping ring of light around a camera or lens and in most front lighting applications these ring lights are the simplest and lowest cost solution to camera lighting. LED ring lights have become so common in close-up and camera illumination you may be inclined to think that all ring lights are the same; however each METAPHASE ring light was carefully designed for each application customers brought to them.

Today METAPHASE makes ring lights in five different diameters from 3" all the way up to 5.75" and with one from row of LED's up to a whopping five. Machined from a solid block of 6061-T6 aluminum all of the ring lights METAPHASE provides are very robust. The proprietary thermal management technology dissipates the internal die temperature externally and ensures a consistent light output for many years. Three 1/4-20 tapped holes provide the ability to mount the ring light directly to the camera. Further the lights are compatible with most camera brackets for direct mounting.

These powerful ring lights are prefocused by the factory for working distances of 1.5" to 4", but also other distances can be provided as required. The ring lights are available in high power MetaBright, standard MetaLight and washdown MetaTight Series.

Off-Axis Ring Lights

  • Illumination of scratches on reflective surfaces
  • Ball grid array (BGA) inspection
  • Water contamination inspection
  • Bottle cap inspection
  • Microscopic stage illumination
  • Inspecting of molded epoxy parts to uncover imperfections such as cracks, bubbles and structural damage

Off-Axis Ring Lights provide a near horizontal plane of light which is useful for highlighting surface defects, illuminating specular surfaces and sidelighting prominent target features.

Dark field illumination provides high contrast lighting for detecting stress, defects, finger prints, edges, dust, and bubbles in transparent materials. When the dark field light is placed behind a transparent object, intense light will appear at the edges and imperfections will be accentuated in a high-contrast manner.

The light can be operated in a continuous mode when used with the METAPHASE SSI-40DC power supply, or in a pulsed mode when used with the METAPHASE SSI-103 LED strobe power supply. These LED strobe power supplies allow operation up to 3600 pulses per minute.

The Off-Axis Ring Lights by METAPHASE are available in standard MetaLight and washdown MetaTight Series.

Diffuse Square Light

  • Inspecting BGA, QFP and other larger format electronic components.
  • Reading large form factor barcodes and 2D style matrix codes.
  • Other square embossed or raised surfaces requiring edge or cavity enhancement.

The new MetaBright diffuse square light is a combination of three different lighting methods all incorporated into one compact package. Having the blended characteristics of a diffused front light, off-axis ring light and edge illuminated backlight its in a category by itself. Like a diffused front light the output is uniform and distributed equally from side to side.

Like off-axis lightings this light is designed to enhance edges and recesses in material surfaces, but unlike its off-axis counterpart it provides a high aspect ratio of diffusion and a tall beam shaping. Like a backlight the optical elements are comprised of trans-illuminated light pipes.

This lights characteristics and its square form factor makes it ideal for illuminating four-sided areas of interest as opposed to the round form factor of the traditional off-axis ring lights.

The Diffuse Square Light is a special light and its applications are very limited. Before specifying, we highly recommend that your application be evaluated by one of the lighting specialists of METAPHASE, who may suggest something else.

Color RGB Light

Color LEDs and different LED emission wavelengths have been used for years as a way to better define colored parts based on the way color affects greyscale shift. More recently color cameras are being used to process images in full color. Lighting a colored object is much different than simple back and white imaging, as colors will react according to a materials chromanance or color temperature. Using complimentary colors and color opposites can also greatly affect the ability to detect areas of interest and enhance contrast.

So far METAPHASE offers RGB in only an elite section of their lightings such as backlights, domelights and linelights but soon much of the products will be available with this exciting new technology.

Instead of changing the light from one color to another by adding color filters, imagine being able to dial in the exact shade of color light you need. As you can see from the color additive mixing diagram below it is now possible to change a lightings color characteristics electronically.

If you have an application that you know would benefit from a full color spectrum approach to lighting we welcome the opportunity. METAPHASE pioneered the first 3 color RGB LED lights and their know-how and experience continues to lead the field in this exciting new area of lighting.

Fluorescent Replacements (Exolight)

Replace your bothersome fluorescent tubes with LED! ExoLight is a cost effective LED replacement technology that obsoletes the common used fluorescent tube. METAPHASE pioneered and patented special anisotropic plastic micro-lens diffusers to create a LED light that emits isotropic light.

What is a isotropic lighting? In short these lights are very "tube-like" in form and size, but mimic the soft diffused output of fluorescent lightings like no other ordinary diffused LED lighting can. In addition to that, these types have more power and a more stable output combined with LED's legendary lifetime and lowest cost of ownership.
