Backlight LED illumination for vision systems based on shadow projection

RODER vision application with led backlight and bottle on belt

The BL3 backlight LED illuminator is specifically designed for use in shadow projection-based systems. By directing light from behind the object or component being analyzed, a shadow of the object is projected onto the camera sensor. The result is an image with clear contrast and high precision, enabling even the most intricate details to be easily viewed and analyzed.

One of the key features of the BL3 is its adaptable design, which enables it to function in various types of imaging applications. The built-in LED lighting ensures consistent and uniform back lighting with no flicker or distortion, making it ideal for use in a range of industrial automation settings.

Moreover, the BL3 is easy to install and operate, making it an excellent alternative to traditional lighting methods. Thanks to its compact and lightweight design, it can be installed in tight spaces without impeding production processes or interfering with the movement of machines and equipment.

Furthermore, the BL3 is energy-efficient, offering significant cost savings on electricity bills. The LED technology significantly reduces power consumption while maintaining superior illumination, making it a truly sustainable solution for any industrial application.

The BL3 backlight LED illuminator is compatible with all types of image processing systems, providing consistent results in both black and white, as well as colour, imaging applications. Its robust build quality ensures optimal performance in even the most challenging environments, making it ideal for industrial automation and quality control settings.

The world of machine vision has long been defined by the technologies that facilitate image capture and analysis. Advanced algorithms and software packages play a major role in this process, but hardware is just as important. Among the most crucial pieces of hardware for machine vision applications are the illumination systems that ensure bright, clear imaging of objects and scenes.

One type of illumination system that has gained popularity in recent years is backlight illumination. This technique involves placing a light source behind an object to illuminate it from the rear, resulting in a high-contrast image with well-defined edges. Backlight illumination is particularly useful in situations where an object has a complex or irregular shape that may have been difficult to capture using other illumination techniques.

With the growing demand for high-quality backlight illumination systems, RODER, a leading developer of machine vision technology, has recently launched a new product called the BL3. This LED backlight illuminator is specifically designed for machine vision applications and promises to deliver superior performance in a wide range of scenarios.

One of the key features of the BL3 is its ability to work with shadow projection systems. This technique involves creating a shadow of the object you want to capture, which is then captured using a camera. By using backlight illumination, the system is able to create highly detailed and well-contrasted shadows, leading to crisp and precise images.

Another important feature of the BL3 is its high-intensity illumination. When used with a shadow projection system, the BL3 is able to produce highly detailed images even in low-light environments, making it an ideal solution for industrial and scientific applications where precise imaging is crucial.

The BL3 is also highly flexible, with a number of different mounting options that make it easy to integrate into a variety of systems and environments. Its compact size and lightweight design make it perfect for use in tight spaces, and it can be easily adjusted to different angles and positions depending on the application.

One of the standout features of the BL3 is its durability. Designed to operate in harsh industrial environments, the BL3 is constructed with high-quality materials that make it resistant to shocks, vibrations, and temperature fluctuations. This makes it an ideal solution for use in manufacturing and automotive applications, where ruggedness and reliability are essential.

In terms of technical specifications, the BL3 boasts an impressive range of features that make it a highly capable machine vision tool. It offers high-intensity illumination with a color temperature neutral, and has an operating voltage of 24V DC. It also has a long lifespan of up to ,000 hours, meaning it can be used for extended periods without the need for frequent maintenance or replacement.

Overall, the BL3 represents a significant step forward in the field of backlight illumination for machine vision applications. With its high-quality construction, impressive technical specifications, and flexible design, it is poised to become an essential tool in a variety of industries where precise imaging is crucial. F
