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 HandbookPressurizationPhotonics HandbookCommon Lens Formulas: Formulas for lens focal length, magnification, relative aperture (f/#), object-to-image distance, object-to-lens distance, lens-to-image distance and numerical aperture.Photonics HandbookIllumination Design and Analysis Software: A Vital Tool in the Designer’s Kit: Optical systems design and analysis software is a key element in an optical engineer’s toolkit. Simulation allows virtual tinkering with a system problem before ever creating — and in some cases eliminating — a prototype. The results can be analyzed to determine real system performance and to suggest changes to optimize the design and enhance performance.Illumination design has developed rapidly to include not only automotive headlamps and street lamps, but also backlit displays, fluorescent panel lighting, light-emitting diode or laser sources, and...WHITEPAPERSPhotonics.com 10/25/2021New Telecentric Optics with Liquid Lenses TechnologyAnyone familiar with telecentric optics knows very well that the depth of field can be a problem when using high-magnification lenses.
