NEW Lite-Mite LABORATORY LAMP

and MAGNIFIER AN ENTIRELY NEW CONCEPT

OF LABORATORY L I G H T I N G

An Ideal Combination

of Intense Cool Light

and Magnification

for Critical Close-up Work Lite-Mite miniature Fluorescent Lamps are extremely compact, small and light weight sources of cool light for use where heat, bulk and weight cannot be tolerated. It provides an intense uniform illumination free from shadow effects. The diffused wide angles of lighting allow superior definition of any object with a maximum of eye ease. For microscope use, it provides sufficient intensity for study of living microorganisms.

FEATURES: • Highly Concentrated, Intense, Non-Glare, Shadowless Light · Cool Light Protection for Specimens · Simple, Long-Life, Rugged Construction · Flexible, Versatile Operation • Portable, Efficient · Rich Appearance — fine baked black wrinkle exterior, baked white enamel reflector.

To the proven instrumentation for X-ray diffraction, which serves as a practical aid in rapidly identifying, comparing and analyzing raw and finished mate­rials, processes, finishes, etc., NORELCO now adds its latest development in X-ray Diffraction Spectrometry — the High-Angle Spectrometer.

Besides achieving higher back reflec­tion angles than hitherto, with a greater degree of accuracy and higher intensi­ties, the Spectrometer incorporates the NORELCO Geiger Tube-Recorder System which provides patterns of relative dif­fraction intensities on a chart—offering definite proof of identity for production control in a relatively short time.
