EyeLight Standard Illumination

EVT offers EyeLight Standard Illumination for industrial image processing.

Next to the lens, is the illumination the second most important item needed for the actual image evaluation.

For mage processing the image and the contrast essential. Therefore offers EyeLight the possibility to

  • to produce the correct contrast and
  • a constant color temperature to reproduce the objects on the sensor.

Which illumination the most suitable is, depends on the application at hand. If you need advise or have any questions you can contact us.

The data sheets for the illumination below are in our download area.

EyeLight Illumination


EyeLight Ring Light
Cost-efficient ring lights for general image process applications for homogeneous lighting. Available are wide-angle as well as dark field and focused ring lights. According to their diameter different working distances are possible.

Diffuse Illumination
Diffuse direct light, produces a light, which shines in a circle from the rim of the illumination into the center, where it is distributed and reflected. This is a very diffuse light, without the LEDs beeing visible on the object.

Indirect Illumination

The LEDs of dome-lights beam light into a dome. The light then is reflected homogeneous and diffuse. Therefore a shadowless, homogeneous and high-contrast light for the object is possible.

The backlight illumination is a plane light panell and is used, where homogeneous light from the back of the object is necessary. Therefore high-contrast images of the object contours are possible.

Bar Light
The light shaped as a bar lights is used for direct and indirect lighting. The bars can therefore be used directly from above the object or else indirectly from various angles to the object.

Online Shop

Coaxial Light
Coaxial light produces a homogeneous light. A semipemeable mirror directs the light of the LEDs, which are mounted on the side onto an optical axis of the lens and therefore creates a very even and shadowless lighting. Defect surfaces will be cast in the dark and the defects will be shown bright.

Spot Light
The LED spot lights are the perfect solution for all applications, which need a precise and extremely bright light. The spots are especially usefull for lenses with coaxial light coupling.

Online Shop

Ingress Protection
Power-LED with specially shaped diffusor for getting a homogeneous light area with high flexibility.
Application examples: reflecting surfaces and food packages.

Line scan Illumination

Extremely bright LED light is focused thanks to a cylindrical lens and this produces a bundled ray of light.

Application examples are especially in combination with line scan cameras.
