A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookAdaptive Optics: Taming Atmospheric Turbulence: For more than three centuries, the Earth’s atmosphere has frustrated astronomers. The layer of gases that we breathe also distorts the images formed by telescopes. This means that conventional telescopes of more than a few centimeters in diameter cannot reach the resolution limit set by their optics.To Isaac Newton the problem was clear, and in 1704 he realized the effects of atmospheric turbulence on image formation. Just as heat waves shimmering above a hot patch of ground can distort our...Photonics HandbookOptical System Optimization: Analyzing the Effects of Stray Light: Stray light can impede the performance of any optical system. With a deeper understanding of stray light, and the right tools, optical engineers can predict and compensate for its effects in order to improve quality.Electrical engineers are very familiar with the effects of shot noise, thermal noise, flicker noise and crosstalk, and recognize how these effects can reduce the signal-to-noise ratio (SNR) in their...Photonics HandbookRules of ThumbPhotonics Rules of Thumb Scientists and engineers tend to want to answer simple relational questions with a blackboard covered with equations, even when questioners just want a rough estimate to...Photonics HandbookWHITEPAPERSModular Spectrometer Delivers High Performance in Compact FootprintIn this application note, we share spectra that demonstrate performance characteristics of the Ocean SR2, a modular UV-Visible spectrometer.
