In the realm of bicycle lighting, adhering to stringent standards ensures not only compliance with legal requirements but also the safety and convenience of cyclists. One of the most critical standards in this domain is the STVZO (Straßenverkehrs-Zulassungs-Ordnung),...
Benefits of wobble welding in high power laser welding systems are explained, features of wobble scan mirrors are reviewed.
A pi-Shaper, also known as the πShaper, is designed to transform Gaussian or similar intensity distributions of source laser beams into flat-top ones. This article describes benefits and trade off
Work experience and proven skills in ray tracing and optimization are important for good optical engineers, so ask potential candidates for examples of their work in these areas before you hire them.
In this article, we will explore a critical aspect of optical design: the K correlation, and how it plays a pivotal role in managing issues such as stray light and light scattering in optical systems, and we will discuss the Bidirectional Scattering Distribution...
Stereo lens pairs are designed to capture two slightly offset images, mimicking the way our eyes perceive the world. When these images are combined and viewed with the appropriate technique, such as stereoscopy, they create a three-dimensional effect, adding depth and...
In the world of imaging and optics, achieving clarity and precision is paramount. Whether it's for quality control, machine vision, or barcode reading, understanding the intricacies of image resolution plays a vital role in ensuring the success of various...
Uses and Benefits of auto collimators for optical assemblies explained
Types of beam expanders and design features are explained
The Foucault Test or ‘knife edge test’ and how they are used in optical metrology is explained
Liquid lenses, are a type of optical lens that have a tunable focal length by shaping a liquid electronically. These lenses can be based on voice coil actuation, or based on electrowetting technology, which involves manipulating the surface tension of a conductive...
Paraxial Lenses Paraxial lenses are a simplified model used to analyze and design optical systems, particularly lenses. In the paraxial approximation, light rays passing through a lens are assumed to be close to the optical axis and at small angles with respect...
The resale value of a used smartphone is highly dependent on the quality of the screen. In this project, we demonstrate methods to automatically identify screen scratches and determine screen quality using a custom imaging and illumination layout and computer...
Optical techniques for distance measurement offer plenty of uses and applications. These techniques are able to measure the distance between two objects without touching them, making them perfect for a variety of situations. Optical techniques are usually the best...
Introduction The Scheimpflug principle is a fundamental concept in optics, particularly in the realm of photography and imaging. Named after its inventor Theodor Scheimpflug, this principle provides a systematic approach to achieving extended depth of field in...
A dispersive prism is an optical element used to break up light into its different wavelength components - a phenomenon discovered by Sir Isaac Newton. By doing this, the prism separates light of varying wavelengths, with longer wavelengths (red) deflecting at a...
In this post we will review textbooks, online tutorials, discussion forums like the ELE Optics Community and software training programs like Zemax training and other great sources to help engineers learn lens design from basic concepts to advanced techniques.
Stray light is a major limiting factor in many imaging systems. When stray light enters the system, it degrades the signal-to-noise ratio or contrast ratio, making it more difficult to obtain accurate images. There are many ways to prevent stray light in an optical system. In this article we will review five.
