Optical systems use lenses to focus, collimate, expand, collect, and image light. Ranging from convex to concave, and bestform to aspheric, any lens selection must be made with the utmost consideration for its purpose as well as its required quality. This white paper delivers a review of singlet spherical lens shapes, and guidance on deciding the best lens characteristics for each application.
Embedding photonic functionalities into an integrated optical chip can often simplify and reduce the size of a system. This white paper introduces the basic concepts of photonic integration with a goal to help the reader understand how it can improve optical systems.
Manual instruments in production are gradually being replaced by automated optical measurement systems, where optimal illumination determines the test quality. A device that illustrates this transition is the ZEISS O-SELECT with an LED ring light from SCHOTT.
This application note provides information on the benefits of SWIR imaging in harsh or low-light level conditions, and PG&O's capabilities in manufacturing optical components for SWIR imaging.
Micro-lens arrays are monolithic components manufactured from synthetic fused silica and a laser writing process, which are created for high accuracy array collimation and coupling. PowerPhotonic designs and develops these micro-lens arrays for applications involving coupling between laser sources, fiber and waveguide arrays, optical multiplexing, and optical switching. This application note discusses micro-lens arrays, as well as the technologies they are used in such as wavelength selective switching, WSS technology, and MEMS and LCoS switches.
Corning Incorporated announced recently that it has entered into agreements with 3M to purchase substantially all of 3M’s Communication Markets Division in a cash transaction valued at approximately $900M. The acquisition is expected to close during 2018, subject to customary closing conditions and regulatory approval.
Scientists have developed novel lenses that enable X-ray microscopy with record resolution in the nanometre regime. Using new materials, the research team led by DESY scientist Saša Bajt from the Center for Free-Electron Laser Science (CFEL) has perfected the design of specialised X-ray optics and achieved a focus spot size with a diameter of less than ten nanometres.
An international research project led by Kazuyuki Takeda of Kyoto University and Koji Usami of the University of Tokyo has developed a new method of light detection for nuclear magnetic resonance -- NMR -- by up-converting NMR radio-frequency signals into optical signals.

Talks by two Nobel Laureates will be among more than 5,200 leading-edge technical presentations held alongside the premier global photonics and laser exhibition, seminars, and training courses at SPIE Photonics West 2018 in San Francisco, California.
Optics is an interesting subset of physics. It is the study of light and how it can be used in various industries from measurements to biology as well as photography to navigation. Optics is a fascinating field and we are just beginning to scratch the surface with what we know. One of the most interesting developments in optics is the use of fiber optics in the transmission of data. Light is used to transmit data across long distances and this has proved to be efficient as well as inexpensive.
Light is the fasted trailing particle in the universe and it is radiated from one point to the next in the form of waves. Light in a vacuum can travel at an astonishing 300 million meters per second, a speed that would take it to the moon in just about one second. Optics is primarily concerned with the use of light and how the light can be reflected, refracted, bent or manipulated in just about any way. The unique nature of light gives tremendous benefits in using it in various industries. Optics is no one of the ways where light can be used to store data. It seems that anything electrons have done in the past, light waves are able to do, just able to do it faster. In the beginning copper cables were used to transmit electrical pulses in network data transfer. While at that time it was a breakthrough, it was comparatively slow to the movement of light through fiber optics. Once fiber optics replaced, broad band speeds were achieved. All thanks to optics. The uses of optics can advance further with headway being made in fields of defense as well as medicine. Optics are now being used to return sight to the blind as well as create sight for robots.
