What is an image chip?
What is an image chip and how does it work? This article explains how image sensors convert light into digital information, why CMOS sensors are standard today and what role sensor size and pixel architecture play in image quality. You can also find out when color sensors make sense and why monochrome chips offer clear advantages in industrial image processing.
Which sensors are suitable for detecting clear glass?
Which sensors reliably detect clear glass? This article explains the most important technologies for transparent materials – from retro-reflex sensors with polarizing filters and ultrasonic sensors to ToF and triangulation sensors. Find out which solution is best suited for glass, PET or film and how wenglor sensors reliably detect even highly transparent objects.
What reflective properties do colored surfaces have – and how do sensors work with them?
Colors are created by the interaction of light and the reflective properties of a surface. The article explains how colored materials reflect and absorb light – and how modern sensors use this information to precisely detect colors. Ideal for use in quality control, robotics and color measurement.
C mount or auto-focus? How to choose the right camera optics for your application
Precise image processing starts with the right optics: when is a C mount lens the best choice – and when is auto-focus worthwhile? Find out which camera optics are optimal for your industrial application and how wenglor Smart Cameras combine the highest image quality and flexibility.
Understanding colors: What is a color space – and why is the RGB color space crucial for sensors?
The RGB color space is central to industrial sensors and image processing: red, green and blue enable precise color detection, digital quality control and reliable color communication in modern production processes.
