Designed to keep pace with ever-improving programming techniques, RCA "MICRO-MESH" Image Orthicons are being acclaimed by station men as the finest camera tubes ever used in commercial television.
With a mechanical exactness heretofore unattainable, RCA MICRO-MESH design has increased the mesh fineness of camera tubes from 500 lines per inch— to 750 lines per inch! This improvement works for you three ways. (1) It enables you to "kill" mesh pattern and moire effect without need for defocussing the picture— whether you are on black-and-white or color. (2) It substantially improves picturedetail contrast. And (3) RCA Image Orthicons with MICRO-MESH are particularly effective in permitting the use of adequate aperture correction to improve detail contrast when the tube is operated below the "knee" of its transfer characteristic— as occurs in color television.
MICRO-MESH design— another RCA original development in TV camera tubesexceeds all present-day requirements for high-quality pictures in all RCA Image Orthicons and Vidicons— at no extra cost to you. RCA camera tubes with MICRO-MESH are available from your RCA Tube Distributor. For technical data on RCA camera tubes, write RCA Commercial Engineering, Harrison, N.J.

CAMERA TUBES FOR TELECASTING
Why Station Men like MICRO-MESH
• Eliminates mesh pattern and moire effect . without defocussing.
• More than meets ail technical requirements of 525-line TV system.
• 750-mesh tube with aperture-correction circuit provides 100% response for 350-line information. 500-mesh tube without aperture-correction circuit permits only about 60% response for 350-line information. Although correction circuit can be used with 500-mesh tube, such use emphasizes moire and beat-pattern problems.
• Micro-Mesh minimizes beat pattern between color subcarrier and frequency generated by beam scanning mesb-screen pattern.
• Improves detail of color pictures.
