Automatic Carbon Coater

The Agar automatic SEM carbon coater is a dedicated unit for routine coating of SEM and microprobe samples, where a conductive low atomic number coating is required. The dual carbon rod source with unique current feedback control gives highly reproducible carbon coatings. In automatic mode, the required voltage setting and evaporation time can be entered and displayed via the digital programmer. A manual and a pulsed mode for coating heat sensitive samples are also included. The adjustable height specimen table allows the working distance to be changed.

Where an accurate determination of coating thickness is required, the manual film thickness monitor, AGB7348, can be used with this coating unit and a vacuum feedthrough is included for this purpose.

Chamber size: 120 x 120mm.

The 108C Auto Carbon Coater offers the choice of either manual or automatic operation. In automatic mode, the evaporation source operates as a programmed voltage for a programmed time. The programmer is simply adjusted and displays voltage and time digitally.

In manual mode, the unique 108C Auto Carbon Coater supply can be operated in "pulse" or "continuous" with the output voltage set using the rotary control.

The 108C Auto Carbon Coater can be fitted with an optional MTM-10 Thickness Monitor. Resolution is better than 0.1nm for carbon. Careful use of the monitor and evaporation controller gives better than 5% reproducibility of coating thickness in the useful 15nm to 25nm range.
