The Brandenburg Alpha Series II 5 kV Power Supply is from Great Britain and made in 1977. The model 2507r is specified for 500 to 5000 VDC at 5 mA, around 100 VA power rating. I bought this Brandenburg Alpha Series II 5kV high voltage power supply from a University in France, cleaning out. I …
Reverse engineering of laser scanner module from a Philips / Fujifilm PCR Eleva S x-ray image scanner / digitizer. Also known as Computerized Radiography (CR), it fulfills the job of scanning a x-ray exposed image plate with a laser beam and extract each pixel illumination with a photomultiplier tube setup. Part 1 pictures and long …
This is a complete teardown of a Philips / Fujifilm PCR Eleva S x-ray image scanner system. Full of stepper motors, laser stuff and photomultiplier tube! If you are specifically interested in x-ray equipment and x-ray image scanners, you are in luck. I have done numerous teardowns and reverse-engineering videos on this kind of equipment. …
