Quality inspection is a crucial part of any manufacturing process regardless of the industry: semiconductor, medical equipment, pharmaceutical as well as food and beverage. This final step ensures that any seal or packaging encompassing the actual product is secure and freed from abnormalities before reaching the mass market, which may be detrimental to both the […]

The selection of right vision components precedes the reliability and repeatability of vision system and determines the quality of the manufactured goods. Having said that, one of the contributing factors to a reliable vision system would be choosing between the right camera and lens.  

An LED is a semiconductor that produces light when electricity passes through it. It is mainly made up of astringent materials such as the p-type and n-type that have been doped to alter their intrinsic properties. In comparison to other lighting such as florescent, LEDs are highly energy efficient as they emit less heat and […]

What is an OLED? OLED stands for Organic Light-Emitting Diode and has a layer with emissive electroluminescent properties containing organic compound which differentiates from the standard LED. With this unique characteristic, it is widely found in digital displays such as smartphones, television screens, computer monitors and portable game consoles. The reason behind OLED being a […]

What are line lights? Line lights are typically used for inspecting a specific area of a workpiece line by line, especially on relatively large objects when the camera is unable to focus on that specific area. Many of these applications include inspection for damage on glass surfaces, visual inspection of circuit boards mounted with electronic […]

Many manufacturing hubs and production plants across the globe have been halted or disrupted by the unexpected emergence of COVID-19 pandemic. The necessity to maintain safe distancing among workers or forced shutdown of plants to curb the spread of the virus has slowed down production rate and saw a decrease in output. As a result, […]

Machine Vision is defined as the ability of a machine system to “see” with built-in components such as camera, lights, lenses as well as an image-processing software that acts as an eye for the machine. Using the results captured by the machine, the next step of the process involves planning and processing the details of […]

What is a UV light? Ultraviolet lights are electromagnetic radiation with wavelengths shorter than the visible light with about 10 nm to 400 nm. UV lighting comes in handy when it comes to applications such as detecting invisible ink, surface sterilization, phototherapy, counterfeit detection, and adhesive curing. Despite of all its pros, the downside of […]

Collimated light is defined as a collimated beam of light rays travelling in parallel to one another and diverges minimally as it proliferates. The parallel light rays suppress the wraparound of light and enables precise dimension measuring and appearance inspection.
