FLI Anti-Dew Technology Option for 63.5mm Shutters
Available option for Microline or Proline cameras that have (or can accept) 63.5mm shutters. Check individual camera models for compatibility.
Anti-Dew Technology (ADT) - In most environments, the temperature of a camera window will be above the dew point. In some cases dew may form on the outside of the camera window due to the combination of high humidity, ambient temperature and the window temperature. The ADT corrects this problem, allowing for operation in very humid environments.
