The Automatic Twin-Jet Electropolisher is an apparatus for the electrolytic thinning of TEM specimens. The twin-jet technique simultaneously polishes both sides of the specimen, creating electron transparent specimens within a few minutes. A photodetector with control circuitry terminates polishing at the first sign of light penetration through the specimen, thus producing a specimen with optimal electron transparent area. Electrolyte flow and polishing voltage are controlled by Automatic Power Control.
应用于透射电镜样品的电解减薄,其强大的双喷技术能够在数分钟内同时抛光样品两面,产生适于电子穿透的薄区.光探头控制灵敏,使得在穿孔的当时停止减薄过程,避免继续减薄损伤薄区.电流电压由自动控制电源连续控制.
