Aspheres...Photonics HandbookUltraviolet Filters: Past and Present: Bandpass filters are passive optical devices that control the flow of light. They are used to isolate certain wavelengths or colors. Applications range from detecting the gaseous composition of a distant star to visualizing the chemical activity in a human cell. Ultraviolet (UV) bandpass filters (with effective wavelength ranges below 400 nm) pose unique design and manufacturing challenges related to the absorption of materials at short wavelengths.In their earliest forms, UV bandpass filters that were optimized for wavelengths less than 400 nm, such as the Schott UG or the Hoya U-series, were constructed of absorbing compounds in glass. Such...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: Optimizing the Design: This second of two articles discusses the tools optical designers need to tailor their designs to the appropriate manufacturing process, optimizing the cost of component fabrication.With the understanding of aspheric lens manufacturing provided in part one of this article, designers have the tools to optimize their aspheres; the next step is to understand how to specify and...WHITEPAPERSPhotonics.com 12/2/2022FISBA READYBeam™ - Compact Powerful Laser SourceThe FISBA READYBeam™ is our answer to customers' increasing demand for compact, powerful, and reliable multicolor laser source that can be easily integrated into existing set-ups.
