3D Printing
3D Printing Though 3D printing may seem like a futuristic concept, the technology has been around for over 30 years. Chuck Hull created the first 3D-printing process in 1983. It was called "stereolithography". The process was described as a "method or apparatus to make solid objects by successively printing thin layers of ultraviolet curable materials [...]
Photoelectric Sensors
Photoelectric Sensors Photoelectric sensors, also known as photoeyes, emit a light beam that can be used to detect items, equipment or surface changes. The receiver measures the light patterns when the light emitted is interrupted by an object or reflected by it. This allows the object or surface to be identified. Photoelectric sensors can be [...]
Know All About F-Theta Lens For Fiber Laser Markers
All You need Know about F theta lens For Fiber Laser Markers F-Theta Lens For Fiber Laser Marking Machine High light transmittance, high output laser energy Marking area is optional from 100mm to 300mm High-quality coating, good protection, uniform laser light Suitable for a variety of fiber laser marking machines with a laser wavelength of [...]
F-theta lenses keep laser-scanning nice and linear
F-theta lenses keep laser-scanning nice and linear F-theta lenses have a laser spot position linearly proportional to the scan angle and are thus useful in many laser-scanning applications. Laser scanning systems are used to scan a spot (or, with two scanning mirrors a line) or to accomplish laser-machining tasks such as drilling or cutting. Laser [...]
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 [...]
