The XQ1410B is a blue sensitive Plumbicon television camera tube.
The lead oxide target camera tube was a Philips invention and was used in broadcast television. This exhibit is branded mullard but was made in Holland by Philips.
The Plumbicon lacked the high edge definition of the Image Orthicon tubes but had the advantage of a high signal to noise ratio.
The Plumbicon camera tube has also been extensively used in medical imaging technology. When television changed to solid state cameras the medical imaging use remained.
The attached PDF is from Amperex (North American Philips) and describes this generation of camera tubes in detail.
