ORTHIC for Color You are looking at the new RCA-7037, an improved image orthicon that has much higher*3 sensitivity— will outperform and outlast any other image orthicon— and retain high sensitivity throughout life. Here are a few of the outstanding advantages of this new tube: (1) Higher effective sensitivity to red, green, and blue permits reduction in lighting level or lens aperture, (2) Increased ratio of blue to red sensitivity provides better balance of the effective sensitivity between color channels with incandescent lighting, (3) A new "stabilized" target greatly reduces any tendency toward an increase in picture "sticking" throughout the life span of the tube— and thus makes possible more hours of service and lowered camera operating cost, (4) Super-Dynode design insures freedom from dynodeburn, (5) Micro-Mesh does away with defocusing to kill moire and mesh pattern, and allows full aperture correction to improve picture-detail contrast. RCA-7037 can be used in place of Type 6474 in all modern color-TV cameras— without changing color filters. RCA-7037's are available now— from your RCA Industrial Tube Distributor.
