Cressington
Carbon Coater 108carbon/A
The Cressington 108 carbon coaters use a novel evaporation supply. Current and voltage are monitored by sensor wires in the head and the evaporation source is controlled as part of a feedback loop. The supply gives the conventional rod fed source unusual stability and reproducibility. Power consumption is low and the source shows exceptional re-starting characteristics. The evaporation source can be operated in "pulse" or "continuous" modes.

The Cressington 108carbon/A offers the choice of either manual or automatic evaporation.

In automatic mode the evaporation source operates at a programmed voltage for a programmed time. The programmer is simply adjusted and displays voltage and time digitally.

In manual mode the unique Cressington supply can be operated in "pulse" or "continuous" with the output voltage set using the rotary control.

Pumping System

The modular desktop design combines carbon control unit, pumping system and thickness monitor into an area of only 42cm x 60cm (16" x 24"). The desktop pumping system is fully integrated using a quick release all metal coupling system. The compact high speed rotary pump (30sec to 0.1mb) is mounted on an anti-vibration table with a desktop base.

The pumping system can be easily extended into a dual pumping system to accomodate the Cressington Sputter Coater along side a Cressington Carbon Coater.
Thickness Monitors

Both 108 carbon coaters can be fitted with a high resolution thickness monitor. Resolution is better than 0.1nm for carbon. Careful use of monitor and evaporation controller gives better than 5% reproducibility of coating thickness in the useful 15nm - 25nm range.
