Geometric Optics vs. Wave Optics Often people working in optics and photonics confuse geometric optics with wave optics, but they aren’t the same thing! Geometric optics treats the propagation of light in terms of “rays”, where each ray travels in a straight line. But in wave optics, we consider the propagation of light in terms […]
Key Takeaways Powell lenses are known as laser line generating lenses, producing straight, uniform laser lines by expanding collimated beams in one dimension. Each lens’s apex showcases an acylindrical curve that evenly redistributes the optical power of a Ø0. A Powell lens transforms a Gaussian beam profile into a cross section with a significantly more […]
Introduction to Laser Beam Expander Lenses Laser beam expanding lens is a common laser device used in scientific experiments, laser ranging, laser printing, and other applications. The laser beam expanding lens can be realized in different forms, such as off-axis reflection, using a couple of prisms to expand the beam, and so on. The most […]
Key Takeaways: A Space Optical Remote Sensing Payload is the part of a spacecraft designed to generate valuable data and transmit it back to Earth. This includes various imaging devices like panchromatic and multispectral sensors, LIDAR, and active optical sensors. These optical payloads also use advanced optics, such as adaptive optical instruments and laser communication […]
Key Takeaways Powell lenses transform Gaussian beams into straight, uniform lines by fanning out collimated beams, eliminating central hot spots for even light distribution. This project focuses on custom-manufactured Powell lenses with specific fan angles and incident spot sizes, exemplified by a 30° fan angle lens designed for a 2.5mm input beam diameter and visible […]
Key Takeaways: Telecentric lenses ensure consistent magnification and high image quality, minimizing distortion and offering a wide depth of field. They excel in precise measurements across varying distances, crucial for quality control in industries like photolithography. These lenses are pivotal for capturing detailed, clear images and detecting imperfections that conventional lenses might miss. Whether for […]
