Smart Coater

Description

The Smart Coater from JEOL USA is an automated sputter coating system used to prepare non-conductive samples for scanning electron microscopy (SEM). It applies a thin, fine-grained conductive film, typically of gold or an optional platinum target, to specimen surfaces. This coating process mitigates charging effects that can distort SEM images and enhances secondary electron emission for better signal detection. The system employs a magnetron-assisted, low-voltage discharge technique for efficient sputtering. A design that isolates the sample stage from the electrode helps minimize potential thermal or electrical damage to sensitive specimens. Final coating thickness is determined by parameters including sputtering duration, the sample's distance from the target, and its position relative to the stage center. The unit operates at a working pressure of approximately 4 Pa and requires a single-phase AC power supply (100V/115V, 50/60 Hz, 650VA). Its compact dimensions are 86 mm in diameter and 100 mm in height, with a hard glass construction.
