Fiber Optic Rotary Joints Add a Spin to Sensing, Mobile, and Robotic Fiber Systems

To the passing optical signals, fiberoptic rotary joints (FORJs) are nothing more than fiber connectors, which provide connection between one or multiple fibers. Their unrestricted ability to rotate, however, gives them a critical role in many sensing, mobile, and robotic fiber systems such as ROVs (remotely operated vehicles), aerostat radars, submarines, satellite antennae, OCT (optical coherence tomography), mining vehicles, cranes, wind turbines, robotic vehicles, broadcasting (mobile cameras), etc. This article discusses some of the applications where optical rotary joints are indispensable. www.princetel.com

All About Aspheric Lenses

The most notable benefit of aspheric lenses is their ability to correct for spherical aberration. Spherical aberration results from using a spherical surface to focus or collimate light. In other words, all spherical surfaces suffer from spherical aberration independent of alignment or manufacturing errors; therefore, a non-spherical, or aspheric surface, is needed to correct for it. Aspheric lenses allow optical designers to correct aberrations using fewer elements than conventional spherical optics because the former gives them more aberration correction than multiple surfaces of the latter. This white paper will discuss the anatomy and benefits of an aspheric lens, the different types of aspheres and how they are made, as well as Edmund Optics custom manufacturing capabilities.
