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. | |||||||

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. |
