In March 1962, RCA demonstrated the first 4-tube camera, the TK-42X (‘X’ for experimental), which incorporated a 4.5” image orthicon tube, as the luminance tube, together with three vidicon tubes to provide the colour information.
The cameras are considered to have been of very good quality, better than the very different TK-42 which succeeded the TK-40/41, and probably better than anything produced by RCA for several years after the production line shut down (NBC didn't fully replace their TK-41s in Rockefeller Center or their Burbank, California broadcast facility ...
1936 saw the arrival of RCA's iconoscope camera. 1946 RCA's TK-10 studio camera used a 3" IO – Image Orthicon tube with a 4 lens turret. The RCA TK-30 (1946) was widely used as a field camera. A TK-30 is simply a TK-10 with a portable camera control unit. The 1948 Dumont Marconi MK IV was an Image Orthicon camera.

The RCA TK-1C monoscope camera that generated the test pattern. Television stations would produce the image of the Indian-head test pattern in two ways. First, they would use a monoscope in which the pattern was permanently embedded, which was capable of producing the image with a high degree of consistency due to the device's simplicity.

Apollo 7 slow-scan TV, transmitted by the RCA command module TV camera. NASA decided on initial specifications for TV on the Apollo command module (CM) in 1962. [2] [ Note 1] Both analog and digital transmission techniques were studied, but the early digital systems still used more bandwidth than an analog approach: 20 MHz for the digital system, compared to 500 kHz for the analog system.

Color broadcast studio television cameras in the 1960s, such as the RCA TK-41, were large, heavy and high in energy consumption. They used three imaging tubes to generate red, green and blue (RGB) video signals which were combined to produce a composite color picture. These cameras required complex optics to keep the tubes aligned.
