TV Camera tubes
Iconoscope

 The Iconoscope was developed by  Vladimir Zworykin, and used in electronic TV broadcasting from 1939 until it was replaced by more advanced tubes.Inside the Iconoscope, the image is projected on a mosaic (M) consisting of granules of photo-emissive material. Emission of photo-electrons from each granule in proportion to the amount of light  results in a charge image being formed on the mosaic. Each granule, together with the conductive plate behind the mosaic, forms a small capacitor, all of these having a common plate. The capacitors are discharged in succession when the mosaic is scanned by a high velocity electron beam (E) from the electron gun, and the resulting changes in potential at the metal plate constitute the picture signal.
The "sensitivity" is 75 000 lux. 
The picture shows RCA 1850A. The price in 1948 was USD 540,-
Image-Iconoscope
This has a kind of electron multipier to improve the sensitivity which has been increased to 1000 lux.
P.E.S-Photikon
Here a bias light is introduced to further improve the sensitivity to 300-500 lux
Orthicon
The electron beam has a relatively low speed and magnetic focusing is needed to keep the beam narrow. The anode is placed in the same end as the electron gun and the return beam is modulated according to the light input.
Sensitivity 3000 lux
Image Orthicon
 
 
The Image Orthicon was a big step forward. It includes a five stage electron multiplier. The picture shows the 3" RCA 5820.
Sensitivity 200 lux
Dimensions: 75 mm diam,  385 mm length, weight 400 grams.
Vidicon


 Sensitivity 500 luxPicture shows:
  Philips XQ1270 3/4", diam 19 mm, length 100 mm, weight 23 g.
Philips XQ1030 1", diam 27 mm, length 140 mm, weight 50 g.
Vidicon with magnetic deflection unit.
The Spectraplex vidicon type 4445 was RCA's attempt to create a single tube color TV camera. They made one camera model with this tube. Further history is unknown.
The size is : diam: 25 mm, length 140 mm.
Weight: 50 grams.
Plumbicon
Philips improvement of the vidicon. The picture shows XQ1074 which were available in three versions, R, G and B for colour TV camera.
And for comparison only:
  A small solid state color TV camera "Mintron" with C-mount for lens. Dimensions: 110 x 55 x 50 mm. Weight: 360 grams excl. lens, 470 grams incl. F1,4/16mm lens. Power needed: 12 VDC, 100mA. Sensitivity:  4 lux.  Output signal: 1,0 Vpp composite video. Can be externally synchronized.
An ultra miniature solid state pin hole color TV camera with 1/4" CCD sensor. Built in 4,3 mm lens / f2,8. Dimensions: 19 x 33 x 29 mm. Weight:  50 grams. Power needed: 5 VDC

(Yes, it is the same matchbox)
A micro sized monochrome camera for surveillance use, type CAMZWCMM. It measures 15 x 15 x 17 mm. Weight: 5 grams, Power needed 12 VDC. Sensitivity 0,5 lux. Made somewhere in Taiwan.
(Still the same matchbox)
