High-Speed Motion, Crystal-Clear Imaging — VY 3.6mm Low-Distortion Lens
In high-speed imaging, scientific research, and industrial vision applications, precision optics can make the difference between accurate data and misleading results. VY Optoelectronics Co., Ltd. is proud to introduce our 3.6mm Low-Distortion Lens, designed to deliver high-resolution, low-distortion imaging across visible and near-infrared spectra, making it ideal for industrial inspection, billiards motion analysis, sports capture, and advanced research. The Science Behind Low-Distortion Lens Design A high-performance lens must maintain clarity across the entire field of view. Traditional lenses often produce barrel or pincushion distortion, especially at the edges, which can compromise measurements or motion tracking. Our design approach includes: Advanced Ray-Tracing and Optical Simulation – Optimizes light paths and reduces aberrations. Precision Aspheric Lens Elements – Minimize spherical aberration and edge distortion. Micron-Level Lens Alignment – Ensures uniform focus across…
The core material of a new type of reflective screen of tungsten trioxide
A new design from Chalmers University of Technology could help produce e-readers, advertising signs, and other digital screens with optimal color display and minimal energy consumption Imagine sitting call at the sun, reading a digital screen as thin as paper, but seeing an equivalent image quality as if you were indoors. because of research from Chalmers University of Technology, Sweden, it could soon be a reality. a replacement sort of reflective screen – sometimes described as ‘electronic paper’ – offers optimal color display, while using ambient light to stay energy consumption to a minimum. Tungsten trioxide is that the core material during a new sort of reflective screen — sometimes described as “electronic paper” — that gives optimal color display and uses ambient light to stay energy consumption to a minimum. The new technology might be utilized in displays for smart devices. Traditional digital screens use a backlight to illuminate the text or images…
Low-Distortion Lens Design for Machine Vision Measurement Systems
Introduction In machine vision measurement systems, a clear image is important. But clarity alone is not enough. For many industrial inspection tasks, the system does not only need to “see” the part. It also needs to measure size, position, distance, edge location, hole diameter, or alignment accurately. This is where lens distortion becomes important. If the lens introduces too much distortion, the image may look acceptable to the eye, but the measured result can still be wrong. A straight line may appear slightly curved. A square may look stretched near the edge. The same part may produce different measurement values in different areas of the image. In real production, this can lead to unstable measurement, false rejection, missed defects, and repeated software correction. For AOI, machine vision, precision measurement, PCB…
