From that beginning the laser has become an integral part of the conventional technology in many production plants. In the forefront of that revolution has been the CO2 laser, today a varied and sophisticated tool.In the three decades since its introduction, the CO2 laser has become the workhorse of industrial lasers. Today it is available in a range of designs and sizes with output powers of 20 kW and more....Photonics HandbookPassive Athermalization: Maintaining Optical Performance Over Temperature: An optical system is athermalized if its critical performance parameters (such as modulation transfer function, back focal length and effective focal length, etc.) do not change appreciably over the operating temperature range.For rotationally symmetric optical systems, either the lens or the detector moves along the optical axis to maintain optical performance. If the compensating axial motion is accomplished without the...Photonics HandbookOTDRs: Finding the Weak Spots in Fiber Links: The optical time-domain reflectometer (OTDR) is used to characterize a fiber optic span. It performs single-ended tests and can calculate fiber attenuation and uniformity and splice and connector losses. It can also locate breaks and determine fiber length. Its ability to locate and measure reflectance and loss makes it the troubleshooting and fault locating equipment of choice. New generation OTDRs include advanced functions such as macrobend location, active-fiber testing and automatic trace acquisition.An optical time-domain reflectometer sends short pulses of light into a fiber and measures its reflections as a function of time. The delay of these reflections to the detector as well as their...Photonics HandbookDigital Cameras: Smaller Pixels for Higher Resolution: Reducing pixel size can increase a digital camera's performance. However, there are tradeoffs that need to be considered when going that route.In the search for ever-higher pixel counts for the digital still camera, it is clear that, if chip size remains constant, then “more pixels” means “smaller pixels.” The...Photonics HandbookWEBINARSBiophotonic Imaging for Medicine: A Digital ConferenceResearchers from around the world presented their latest work at “Biophotonic Imaging for Medicine: A Digital Conference.” Presentations focused on a range of light-based imaging and...Photonics.com 6/11/2015How to Accelerate Your Optics, Photonics, and Imaging Startup with LuminateSolving problems in augmented and virtual reality, autonomous vehicles, machine vision, biophotonics, and other fields requires unique skills.
