Industrial Machine Vision Bottom Lit Backlight Series
Bottom lit backlights are industrial LED lights for illuminating products in machine vision applications like dimension measuring of parts, robot pick and place in computer vision applications, inspection of translucent objects or contour defects checks. Bottom lit backlights are available in different sizes and light colors. The standard colors are White, Red, Green or Blue. On request also UV and IR Bottom lit backlights are possible. If you can't find the right size, we can customize the bottom lit backlights to fit your illumination request. Click here for the datasheets.
When to use bottom lit backlights in your machine vision application?
Bottom lit backlights are regularly used lights in machine vision applications. They are very versatile. You can use them in combination with our industrial cameras in computer vision applications where you are inspecting:
- Objects that don't require light on the camera side of the object
- Objects that are flat. In case you want to inspect edges on a non-translucent object

How to use bottom lit backlights for illumination
Bottom lit backlights are commonly used by placing the light behind the object. This creates a contour of the object and it is easy to do a defectivity check. Optionally, we have a bottom lit collimated backlight version available. We recommend using the power supplies as indicated in the datasheet to control the brightness of the bottom lit backlight. Additionally, these power supplies give you the option to trigger the backlight. Triggering the lights will increase their lifespan.

Production and quality control of bottom lit backlights
Our LED bottom lit backlights long distance 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 bottom lit backlight long distance production is automated and involves placing the LEDs on a PCB that fits the bottom lit backlight long distance, 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 bottom lit backlight long distance. Post-assembly, the bottom lit backlight long distance undergoes testing to ensure that performs according to its specification. This critical phase ensures that each bottom lit backlight long distance unit meets our uncompromising quality standards.
The production process of the bottom lit backlight long distance 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 bottom lit backlight long distance 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 bottom lit backlight long distance, we have established a room dedicated to light-source age testing.
During the R&D phase of a new bottom lit backlight long distance, it will be continuously on for 1 week, while the temperature is monitored. For every new production run, each bottom lit backlight long distance will be continuously powered for 12 hours, ensuring that the quality and output of our machine vision lights remain uniform over time.
