Key Takeaways The diffraction limit is the fundamental resolution limit of an optical system, dictated by the wave nature of light and diffraction. When light passes through an aperture, it forms an Airy disk—a central bright spot surrounded by rings. The smallest focusable point, or minimum spot size, is defined by this disk. Calculated as […]
Read moreKey Takeaways: Reflective optics, essential for fields like astronomy, life sciences, and industrial applications, utilize mirrors to direct wavefronts. Mirrors are either first surface, with coatings on the front, or second surface, with coatings on the back, affecting their use in precision optics. Reflective coatings can be metallic, dielectric, or hybrid, tailored for durability and […]
Read moreGeometric 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 […]
Read moreKey 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 […]
Read moreIntroduction 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 […]
