How F-Theta Lenses work ( & when to use one)
A scanning system moves a laser in two or three dimensions linearly, usually by using scan mirrors or galvanometers. The laser beam can be focused to engrave images on different materials and for drilling, cutting, or other applications. When using traditional lenses for this application, however, the profile changes as the focus beam moves away. [...]
F-Theta Lenses Tutorial
F-Theta Lenses F-theta lens technology has been developed to deliver the best performance possible in laser scanning and engraving systems. These lenses are perfect for image transfer and material processing, as well as engraving and labeling. A planar imaging field will give the best results for many laser scanning and engraving applications. A spherical lens [...]
Understanding Computer Vision
Understanding Computer Vision Understanding Computer Vision Someone throws the ball. The ball is caught by the other person. Simple, right? Not really. It is one of most complex processes that science has attempted to understand, let alone recreate. It is surprisingly difficult to create a machine that can see the same way as a human. [...]
3D Printing And Terahertz Radiation
3D Printing And Terahertz Radiation 3D Printing And Terahertz Radiation 3D Printing And Terahertz Radiation is used for a variety of purposes, including airport security checks or material analysis in laboratories. This radiation has a wavelength that is much larger than visible light wavelengths, being in the millimeter-range. The beams must also be shaped using [...]
Automotive Cameras
Automotive Cameras There are many types of cameras in the automotive industry today. These automotive cameras offer solutions for different problems. Safety comes first, then security. Many vehicles are equipped with front, rear and backup cameras. They also have side, far-view and rear-view cameras. In fact, all vehicles sold and manufactured in the U.S. since [...]
3D Scanning
3D Scanning 3D scanning involves capturing data from the real world and converting it to a 3D version. 3D scanners have been used primarily for industrial purposes until recently. 3D printing, particularly for hobbyists and professionals, is on the rise. The demand for 3D scanners that can turn real objects into 3D printable model is [...]
Photo Eyes – Photoelectric Sensors
Photo Eyes – Photoelectric Sensors In the field of industrial automation, a sensor is a device that detects presence, such as a limit switch, pixel (photoelectric), or laser sensor. Industrial sensors are available in all sizes, shapes and technologies. They are the eyes and ears on factory floors. The application requirements will determine which technology [...]
What is an M12 Lens / S-mount Lens?
M12 Lens M12 Lens (M12 Board lens) is also known as S-Mount Lenses and Micro-Video Lenses. They focus an image on a camera sensor. These lenses are used for a wide range of applications, including automotive, forensics and pharmaceuticals. These S-Mount lenses are compact imaging lens designed to be used with many small-format industrial cameras. [...]
