Cressington 208C High Vacuum Turbo Carbon Coater

The 208C High Vacuum Turbo Carbon Coater from Cressington offers high-quality carbon coating techniques for TEM, STEM, SEM, EDS/WDS, EBSD, and microprobe applications. The practical chamber size of 150 mm diameter allows for rapid pump down and coating cycle times of around 10 minutes. The use of ultra-purity carbon rods in a high vacuum chamber provides high-quality coating needed for critical TEM, EBSD, high-resolution SEM, and microprobe work.

The 208C uses a unique, fully integrated electronic feedback-controlled power design for the rod-fed Bradley-type carbon evaporation source. Current and voltage are monitored by sensor wires in the evaporation head where the evaporation source is part of the feedback loop. This feature gives the conventional rod-fed carbon source unusual stability and reproducibility. The carbon source uses two-step ultra-pure carbon rods. The evaporation source can be operated in manual "pulse" or manual "continuous" modes. The pulsed mode, when used in conjunction with the optional MTM-10 high-resolution thickness monitor, gives absolute control over the desired thickness of the carbon coating. The automatic mode lets the user set the voltage and time, which together with the two-step rods gives consistent coating combined with ease of operation.
