  • Precision Refractive Zoom Lens with Long Focal Length (.pdf)
    ," are more commonly used with an afocal system, but the terms allow classification of. the lens groups. For example, the focal length is more sensitive to movements of the variator than the compensator. Stop. 199 mm. 76 mm. 2 mm. Image. f - 750 mm. Filter. Objective. Relay. "Eyepiece". Variator. f - 1750
  • Focusing Objective Theory (.pdf)
    Some focusing applications may require a higher degree of aberration correction than can be achieved in single lenses such as Bestforms. Whether correction over larger apertures, several wavelengths or a wider field is needed, it may be necessary to use multi-element lens objective

  • Near Field Imaging of a Laser Diode Using Scanning Method
    Newport fiber mounts were. where s is the distance from the source to the lens. used, as shown in figures below. We also tested other. lenses, such as an Olympus PMPlan 100X, a Newport. s' is the distance from the image to the lens. M-20X objective, and a biconvex lens. f is the focal length
  • Thermal Imaging to Study the Heating Pattern of Wheat in an Industrial Microwave Drier
    Several researchers have been using microwaves to dry grain and other agricultural materials. But nonuniformity of heating pattern was observed in different food materials during microwave cooking. The objective of this research was to evaluate the heating pattern of wheat during drying

    , Germany), motorized translation stage TS1b (MP 285; Sutter Instruments, Novato, CA), blue-green filter F (BG38, 370043; Linos), lens L7 (focal length 2.5 cm, 063021; Linos), photomultiplier tube PMT (R3896; Hamamatsu, Hamamatsu City, Japan), CCD (XC-77; Sony, Tokyo, Japan), group velocity-dispersion
  • Two-Photon Excited Fluorescence Microscopy
    the objective on the right is focusing 800 nm light. from a femtosecond pulsed laser. When the solution is. excited by a one- photon process at 405 nm, fluorescence is. (1). generated everywhere along the optical axis. Upon two-. photon absorption at 800 nm, fluorescence is observed. exclusively at the focal
  • Optical Dictionary
    infrared lasers). Achromatic lens: A usually two-element lens that is corrected for chromatic aberration to bring two specified or distinct wavelengths to a common focal point. Active medium: Collection of atoms capable of undergoing stimulated emission at a given wavelength. Afocal: Literally, "without
