EDAX's Octane Silicon Drift Detector (SDD) Series for the Transmission Electron Microscope (TEM) offers the crucial analytical solution for TEM applications. EDAX was the first to launch a windowless SDD, which gives the most favorable light element performance with full transmission of low energy X-rays.
In comparison to a SUTW detector, the sensitivity of the light element was up to 500% better and the count rate was improved by 30% for heavy elements. Therefore the outcome is the mapping speed and light element recognition in low concentrations are greatly improved with the windowless design.
There are three types of SDD machines. The Octane T Plus is an entry-level SDD with a Super Ultra Thin Window (SUTW) that is also cost-effective. The Octane T Optima is formulated on a column-specific plan providing a windowless detector with solid angles up to 0.5 sr. The Octane T Ultra is a high-performance analytical TEM with solid angles up to 1.1 sr.
