Eon-LT with Mirage Air Cooling Module


Temperature-Reading Film Thickness Monitor
Compact, Affordable PC-Based Film Thickness Monitor


Eon-LT is a temperature measuring film thickness monitor that surpasses conventional monitors that are blind to thermal changes of the crystal. The combination of frequency and temperature measurement allows unprecedented accuracy in real-time rate and film thickness monitoring.

Why measure temperature? Because the frequency change of a crystal by process heating can easily be equal to the frequency change caused by coating. In normal operation there is a built-in 10% error in most rate measurements. In the worst case it can be 100%. Why measure if your measurements are always wrong?


  • Temperature measurement for added precision
  • Shutter on/off support (relays)
  • Connectivity: RS-232, USB, and WiFi
  • Operated using the included, easy-to-use software or controlled via Colnatec’s
    documented RS232 protocol.
