Dark field lighting

Illumination is the most critical component of machine vision systems because a poor-quality image makes it more difficult to get reliable data. Gaining precise control of your lighting can be crucial, particularly since factors such as the direction, wavelength and intensity of the illumination can all affect the captured image.

Consistent light levels are essential to guarantee repeatable results in Machine Vision systems. Typical systems that monitor, regulate, check, analyse, sort or classify products need high precision and repeatability, and in many industries, only 1 in 100,000 reject products can be tolerated. To meet such high tolerances, the reliability of the system measurements needs to be even better. For example, if you are making a simple caliper measurement then a 10% reduction in light level can typically cause a change in the measured values of around 0.5% which can severely affect the reliability. For this reason, light intensity must be closely regulated.

Despite thorough disinfection, stains and mildew can sometimes persist on beer bottles. Identifying these defects early is crucial to remove flawed bottles before reuse. The inspection process is challenging due to the need to rotate and move the bottles and potential obstructions from product labels. These factors render manual inspection and conventional vision systems inefficient and impractical.

Full size LED truck light bars are available in a variety of sizes to provide warning light around your tow truck, construction or utility vehicle.

SolVision, an advanced AI vision system, elevates the inspection of beer bottles. Capable of training an AI model with a small set of sample images, SolVision learns to detect various types of stains and mildew. Its powerful segmentation tool accurately identifies the location, color, and features of defects in real-time on the production line. This thorough inspection ensures that all contaminated areas are promptly identified, making the cleaning and recycling process safer and more efficient.

A number of factors will affect the intensity of LED lighting. These include the age and temperature of the light and external factors such as ambient light or dirt on the light. Although some machine vision lights have a voltage rating, their light output is actually controlled by the current through the LED and not the voltage across it. In fact, a very small voltage change will cause a much larger change in brightness. For example, a 1% decrease in voltage can cause a 10% reduction in light output. For this reason, a lighting system that is driven by a voltage source will be inherently susceptible to any electrical interference or variation in power supply.

Terminal kits are a great way to access a wide variety of wire terminals and connectors in one place.

Gardasoft controllers drive lighting with a constant current drive which will give stable and repeatable light output. For simple applications involving a single light, the entry level RC120 will provide stable and repeatable illumination for machine vision systems. This controller has an Ethernet interface and can be easily configured using its internal webpages.
