32 value analyzed benefits give G-E Image Orthicons 3 to 5 times longer life, highest sensitivity, and unsurpassed performance in your cameras
G.E.'s family of "station designed" Image Orthicons cover the complete spectrum of commercial and educational television. Individual types incorporate certain value analyzed benefits which optimize performance for any given program requirement, whether specialized or broad. These benefits can extend life to as long as 8000 hours . . . provide signal-to-noise ratios up to 50:1 . . . and allow high resolution pickup at 1 ft.-c for black and white, or 40 ft.-c for color.
Q Distortion-free optical quality glass is used in all G-E Image Orthicon faceplates • Fibreoptics faceplates prevent picture distortion
Q Photocathodes— Spectral response close to that of the human eye permits portrayal of scenes in nearly their true tonal graduation • Individual processing for each tube guarantees uniformity of characteristics and maximum sensitivity
Q Semiconductor (MgO) thin-film target gives high sensitivity with only 1 ft.-c for blackand-white pickup . . . only 40 ft.-c needed for color • 0.000002" thick, MgO target gives: greater resolution • extremely long life • no stickiness • improved depth of focus • no target raster burns-GL 8092— GL 7629
Q Glass target only 0.0001" thick prevents loss of resolution due to lateral charge leakage • Specially selected optical quality glass is free of imperfections— GL 5820A — GL 7293— GL 8093
Q Electroplated target mesh, with 560,000 openings per square inch, improves picture detail, prevents moire and mesh-pattern effects without defocusing
Q 750-line field mesh screen— makes the scanning beam approach the target perpendicularly over the entire area • improves corner resolution • diminishes white-edge effect • Shading and dynamic match for color pickup are excellent • Set-up time is reduced
Q As an added precaution against moisture contamination, dry inert gas is blown through the envelope prior to exhausting and sealing • Longest tube life is assured
Q To prevent contamination from dirt, dust or moisture: All personnel wear lint-free clothing • operators wear nylon gloves or finger guards • assembly rooms are pressurized, the air super-cleaned, and humidity controlled
Q Precision manufacture, plus accurate spacing and alignment of all components, assures uniform signal gain in the multiplier section • Dynode material and design, plus a 0.0012" aperture, allow sharper target focus • No compromise between sharpest focus and dynode blemishes appearing in background • Less set-up time required
Q Performance testing— Every tube tested prior to release to customer • Tests are made in G.E. and other-make cameras to guarantee highest picture quality and complete operational flexibility
