Putting that knowledge to work requires an understanding of the tools of the trade and how to use them.All optical spectrometry techniques rely on the measurement of radiant power. The configuration of the instrument varies based on the measurement technique: absorption, emission, luminescence, or...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 HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...WHITEPAPERSPhotonics.com 2/23/2023High-Resolution Raman & Photoluminescence Imaging of MoS2In this application note, the transition-metal dichalcogenide molybdenum disulfide (MoS2) is characterised using the RM5 Confocal Microscope with Raman and photoluminescence imaging to characterise...Photonics.com 2/23/2023Multimodal Raman, Photoluminescence & SHG Imaging of CVD Grown WSe2In this application note, the transition-metal dichalcogenide tungsten diselenide (WSe2) is characterised using the RMS1000 Confocal Microscope with five imaging modalities: reflected brightfield and...Photonics.com 10/19/2022Multiphoton Imaging of Mouse IntestineTwo-photon excited fluorescence (2PEF) and second harmonic generation (SHG) are complementary multiphoton imaging techniques for studying biological samples.
