90kV Hamamatsu Microfocus X-ray Source

First starting from the founding of Tokai Electronics Laboratory in 1948, Hamamatsu TV Co., Ltd. was then established in 1953 followed by a company name change to Hamamatsu Photonics K.K. in 1983. All through this period and up to the present day, we here at Hamamatsu Photonics have been continually pursuing technologies involving “light” in all its aspects.

Microfocus X-ray sources specifically developed for 2D and 3D nondestructive testing. A small focal point prevents blurring of x-ray images and delivers a sharp, enlarged image.

1. Focal Spot Size: 5μm (at 4W)
The focal spot of 5μm of the sealed type X-ray tube enables sharp and clear X-ray images even at a high magnification.

2. Easy Handling
Fully operable from an external PC.

3. Serial Port Control
One package of a sealed type X-ray tube, a high-voltage power supply and a control function.
