An optical coating is a vital technique with many applications, including creating glasses for those with light-sensitive eyes and improving camera lenses. This article will cover all you need to know about optical coatings, such as what it is, how it works, and various types and technology. What Is Optical Coating? What is the optical […]
Read moreWhat Are Cylinder Lenses? While less popular than convex or concave lenses, cylindrical lenses are just as important. This is because they perform certain functions that other lenses cannot. This article contains everything to know about cylinder lenses, from how a cylindrical lens works to what it is used for. So why do we use […]
Read moreOptical surface accuracy refers to the difference between the actual shape and the desired shape of an optical surface. It is a crucial aspect of optical components and is typically measured in terms of fringes or waves that correspond to the laser wavelength used in the interferometer. And it is important to specify the expected […]
Read moreKey Takeaways: The main difference between a mirror and a lens lies in their functionality; while a mirror possesses a reflective surface, a lens refracts light, with various types of mirrors including plane and spherical mirrors. Mirrors are typically made with a reflective coating, while lenses are transparent and refract light passing through them. Mirrors […]
Read moreOptical Tolerances In real manufacturing, a certain amount of error will unpreventably occur between the measured value and the designed value. In terms of measurement, the difference between the maximum and minimum dimensions of permissible errors is called tolerance. If it is written on the drawing that “3.5 +0.05/-0.00“, “3.5” represents the reference dimension, “+0.05” […]
Read moreWhat Are Telecentric Lenses? A telecentric lens is a type of optical lens that has an infinity for both or either its entrance or exit pupil. These lenses are important for Industry applications that specifically demand perfect precision with two-dimensional measurements. Telecentric lenses are effective in imaging objects that are subject to size distortion due […]
Read moreBoth fisheye and wide-angle lenses are used in situations that need a wide field of vision. Either one provides an extensive visual angle. So, what distinguishes one from the other? And what is the best situation for each type of lens? If you need lenses that can provide you with a wider vision, then you’re […]
Read moreA beam splitter is applied in various fields, from teleprompters to robotics. Without it, a lot of technology you know would not function. So, how does a beam splitter work? What are its types and applications? This article will cover what a beam splitter is, where it is applied, and the various types that exist. […]
Read moreIn microscopes, objective lenses are the most complex and most important part of the microscope. The objective lenses, which are designed as multi-element lenses located closest from the specimen, the function is to receive light emitted by the specimen, and perform the crucial task of producing real image, then get it received by the eyepiece […]
Read moreKey Takeaways Optical filters like Longpass, Shortpass, Bandpass, Multi-bandpass, Notch, and Neutral Density are essential for controlling wavelength ranges in diverse applications. The electromagnetic spectrum comprises Gamma rays, X rays, UV, visible light, IR, and radio waves. Human eyes perceive colors in visible light (380-780nm), while optical filters play a vital role in manipulating light […]
