The metal-ceramic tube is encapsulated in silicone rubber, enabling flexibility in tube housing design for different system configurations. The Epsilon 4 with W-anode is available in a 30kV and 50kV version.
The compact metal-ceramic design allows for a very close coupling of sample to anode, yielding high intensity at low power settings. Furthermore, the Epsilon tube can be operated over a wide range of kV settings (4 - 50 kV), enabling high power and intensity even at low kV.
The metal-ceramic design of the Epsilon tube ensures a much better stability of X-ray output than in traditional glass tubes. This results in excellent stability throughout the entire life time of the tube.
