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 compact, turbo pumped system requires only a standard power outlet and occupies minimal bench top space. the practical chamber size of 150mm 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 gives the high quality coating needed for critical tem, ebsd, high resolution sem and microprobe work. the modular design permits rapid change between a variety of applications with optimized conditions.
optional accessories for the 208c:rotary-tilting stage for coating large samples like microscope slides for carbon support films.rotary-planetary-tilting stage for multiple sample coating for sem, eds/wds and ebsd applications and/or enhanced uniformity.mtm-10 thickness monitor unit for precise and reproducible coating thickness.
main features of the 208c• voltage controlled rod source gives multiple evaporation capabilities.• feedback loop enables precise and consistent coating thickness.• choice of operation methods for optimized operation.• automatic evaporation control gives ease of use in busy environments.• low cost, high resolution thickness monitor ensures reproducible results.• 80 ltr/sec turbo pump on a 150mm diameter chamber gives rapid pumpdown.• optional dry scroll pump available• reduces operating cost in several ways:1、no need for water cooling2、no need for warm up or cool down3、noneedforln2(drynitrogen gas optional)4、short cycle time5、space saving，compact bench top design
