81105 Cressington 108 Sputter Coaters are ideal for routine sample preparation. Compact, economical and simple to operate, they offer rapid pumpdown times, fine-grain coatings and negligible sample heating. Cool, fine-grain sputtering is achieved with a very efficient dc magnetron head. A quick-change target method allows a range of metals to be used. The variable, safety-interlocked sputtering supply is not influenced by vacuum level. Although it is the simplest sputter coater in the Cressington range the 108 has an excellent specification. The standard 108 has fully variable current control, digital process timer with "pause", variable height specimen table, hinged top-plate and o-ring sealed vacuum chamber. The current controller allows independent choice of sputter current and argon pressure. Coverage and grain size are optimized for any specimen. The 108 can be fitted with a Cressington MTM-10 high resolution thickness monitor system. Pumping System The modular desktop design combines sputter control unit, pumping system and thickness monitor into an area of approximately 16" x 24" (42cm x 60cm). The desktop pumping system is connected with a metal coupling system. The compact high speed rotary pump is mounted on an anti-vibration table with a desktop base. The pumping system can be easily extended into a dual pumping system to accommodate the Cressington Sputter Coater along side a Cressington Carbon Coater.
