Coaxial light industrial illumination series VA-COL3, Select your size / color, Industrial illumination

Industrial Machine Vision Coaxial Light 3 Series

Coaxial lights are machine vision lighting 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 in your computer vision application. Our coaxial lights are available in different sizes and light colors. The standard colors are White, Red, Green or Blue. On request also UV and IR coaxial lights are possible. If you can't find the right size, we can customize the coaxial light to fit your illumination request. Click here for the datasheets.

When to use coaxial lights in your machine vision application?

Coaxial lights are suited for machine vision tasks where precise imaging and minimal reflections or shadows are crucial. Commonly used in inspections where a direct, on-axis light source is necessary to capture fine details without interference.

• Objects that are flat and highly reflective
• Objects that are not flat and reflective. These diffuse objects can always be illuminated with coaxial lights

In case an object is not flat and reflective, we strongly recommend to use bar lights for illuminating your product.

How to use coaxial lights for illumination

Coaxial lights are mounted in front of the machine vision lens/industrial camera setup and direct the light parallel in line with the camera. We recommend using the power supplies as indicated in the datasheet to control the brightness of the coaxial lights. Additionally, these power supplies give you the option to trigger the coaxial lights. Triggering the coaxial lights will increase the lifespan of the coaxial light.

Production and quality control of coaxial lights

Our LED coaxial lights 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 coaxial light production is automated and involves placing the LEDs on a PCB that fits the coaxial light, 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 coaxial light. Post-assembly, the coaxial light undergoes testing to ensure that it performs according to its specification. This critical phase ensures that each coaxial light unit meets our uncompromising quality standards.

The production process of the coaxial light 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 coaxial light 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 coaxial light, we have established a room dedicated to light-source age testing.

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