WIDE DYNAMIC RANGE

MICROCHANNEL PLATES

F6584 SERIES

20 µA Output Current is Available *

The F6584 series is a wide dynamic range MCP that offers more than ten - fold increase in maximum output current

compared to conventional MCPs. This increased current capability is due to low plate resistance. When operated in pulse

counting mode, the F6584 series MCPs also provide maximum counting capability that is more than ten - fold higher than

conventional MCPs. The design is optimized to prevent resistance reduction resulting from high power consumption or

high temperature operation.

The F6584 series MCPs therefore offer excellent stability and reliability even during high current or high temperature

operations. This results in a very wide dynamic range, making these MCPs ideal for various applications such as mass

spectrometers and usage for high counting PMTs.
