ECLIPSE-IV is a self-contained miniature X-ray tube system, which includes the X-ray tube, the power supply and the control electronics. It is designed to replace radioisotopes in X-ray fluorescence analysis applications.
ECLIPSE-IV has been designed to simplify the XRF process by providing grounded anode, variable current and voltage, and ease of operation. It features a 45 kV/50 µA power supply, a rhodium (Rh) transmission target, and a beryllium end window.
To further simplify the use of ECLIPSE-IV, a portable Controller is provided, powered from 80 - 240 V AC. The Controller generates all the voltages needed to operate the x-ray tube and provides both voltage (kV) and current (µA) display and control. A flashing red LED and a beeper warns the user when x-rays are present.

The ECLIPSE-IV Is intended to generate x-ray radiation during normal operation. The ECLIPSE-IV has been designed to focus radiation in the designated output direction, however radiation in other directions is possible and should be addressed with shielding and/or monitoring in the final application.
This device produces X-Rays when energized. To be operated only by qualified personnel.
CAUTION: The Eclipse is only one component of an X-ray instrument. It is the responsibility of the user, the OEM customer, or experimenter to provide a fail safe metal enclosure to prevent escaping radiation while using this product. The final product (turn-key system) must comply with local government regulations to protect personnel from exposure to radiation. Amptek Inc., bears no responsibility for the incorrect use of this product.
