Industrial Machine Vision Side Lit Direct Backlight 2 Series

Side Lit Direct Backlight are industrial LED lights for illuminating products in machine

vision applications like surface defects on metal parts, character inspection on printed material, inspection of PCB components and positioning and recognition of large field objects. Our Side Lit Direct Backlight are available in different sizes and light colors. The standard colors are White, Red, Green or Blue. On request also UV and IR Side Lit Direct Backlight are possible. If you can't find the right size, we can customize the Side Lit Direct Backlight to fit your illumination request. Click here for the datasheets.

When to use Side Lit Direct Backlight in your machine vision application?

Side Lit Direct Backlights are the most commonly used lights in machine vision applications. They are very versatile. You can use them combined with our industrial cameras in computer vision applications where you are inspecting:

Objects that are flat. In case an object is reflective, you need to adjust the angle of the light that there is no direct reflection into the camera image
Objects that are not flat and not reflective. These diffuse objects can always be illuminated with Side Lit Direct Backlight

In case an object is not flat and reflective, we strongly recommend using a dome light for illuminating your product.

How to use Side Lit Direct Backlight for illumination in computer vision

The light is placed above the object. The camera and lens are looking through the light. The distance from light to lens must be large enough, so the lens is not looking against the light.

Production and quality control of Side Lit Direct Backlight

Our LED side lit direct backlights are produced with a strict process of quality control, to ensure their reliability and consistency. Upon receiving a new batch of LEDs, the quality department completes a comprehensive check to test whether the wavelength falls within the specified tolerances. Approved LEDs are stored in a climate chamber, ready for use in production. The next stage of side lit direct backlight production is automated and involves placing the LEDs on a PCB that fits the side lit direct backlight, which is then followed by an inspection and soldering. Moving along the production line, the LED boards are assembled into the mechanical housing of the side lit direct backlight. Post-assembly, the side lit direct backlight undergoes testing to ensure that it performs according to its specification. This critical phase ensures that each side lit direct backlight unit meets our uncompromising quality standards.

The production process of the side lit direct backlight may also include the creation of a diffuser or polarizer. The diffuser is cut automatically, and every batch of diffuser plates undergoes transparency testing before they are cut into the correct shape. The final step involves a comprehensive quality check, where the intensity, voltage, and current of each side lit direct backlight are meticulously measured. This step guarantees that all machine vision lights that leave our facility meet the required specifications. To further ensure the long-term consistency of our side lit direct backlight , we have established a room dedicated to light-source age testing.

During the R&D phase of a new side lit direct backlight, it will be continuously on for 1 week, while the temperature is monitored. For every new production run, each side lit direct backlight will be continuously powered for 12 hours, ensuring that the quality and output of our machine vision lights remain uniform over time.
