• Factors to Consider When Selecting a Stereo Microscope
  is that? Because it depends on the application, on the task the user wants to achieve. Basically, a stereo microscope is a tool for magnifying a three-dimensional object in three dimensions. Unlike a compound microscope, a stereo microscope is able to cope with this task. Part of the Topic. Basics...
• Introduction to Achromatic Lenses
  The optical performance of compound lenses (two or more single elements designed to work together) is superior to that of single lens elements working alone. Achromatic doublets and triplets are compound lenses composed of two and three singlets. Designers often abbreviate their reference...

  with suckback control allows filtration and dispense operations to occur at independent rates. The unit's dispense function operates at a different rate than its filtration function. By using slower flow rates while filtering, the system reduces gels and bubbles and prevents fluid shear from altering high...
• Getting Plant Genes To Glow: New technique emerges from metal absorption studies
  , are expressed," says research leader Leon V. Kochian. "It provides immediate data that can be used in many ways." Kochian explains that knowing where in what tissues or organs a gene and its product are expressed greatly helps researchers understand its role in plant function...

  elasticity of a blood clot and its ability to stop bleeding during medical procedures. It relies on two greases, one in the gear motor and the other where mating parts slide on the frame. A subfractional horsepower electric gearmotor by Autotrol Corp., Crystal Lake, Ill., powers the TEG Analyzer...

  , the detector signals the control unit of a fire suppression system that is part of the complete detection and suppression package. The sealed polypropylene detector housing has an IEC 529 IP 67 rating. Its surfaces are smooth, nonshedding, scuff resistant, and accessible for wipedown. Microwave...

  be considered either a tool or a component. Although a flat in an interferometer does not come into direct physical contact with the surface under test, the principle of operation that explains its function as a component in the interferometer is the same principle that explains its function...
• Introduction to Mirrors
  in the same place, whereas a simple or even well-corrected compound lens will suffer from some chromatic aberration. Surface contour and reflectivity are two basic operational characteristics of a mirror. Surface contour determines image-forming properties while reflectivity determines image brightness...

  resolution. Its Aerial II illuminator provides a transmission of 248-nm-wavelength light. Overlay accuracy using a through-the-lens phase-grating alignment system is specified at <40 nm for single-machine and <60 nm for matched-machine applications. The tool's Athena alignment scheme uses two...
• Glossary of Forging Terms
  specified to reduce die costs where only a small number of forgings are desired and the cost of machining each part to its final shape is not exorbitant. Bloom A semifinished product of square, rectangular, or even round cross section, hot rolled, or forged. For steel, the width of a bloom...
