TEM2 (Russian: ТЭМ2) is a Soviet diesel-electric shunting locomotive. The locomotive was used throughout the Soviet Union and was exported to Poland and Cuba.

TEM2 is an upgraded version of the TEM1, with 883 kW of power and the same tractive effort as the TEM1, but with an increased speed and a reduced weight. The first prototypes appeared at the Bryansk factory in 1960, with several pilot batches of …

The TEM 2 series is a family of isolated dc/dc converters in a DIP-24 package. They offer tight line/load regulation and 1000 VDC I/O isolation. Standard features in-clude an internal filter to reduce reflected input ripple currrent and to guarantee low output noise.

与扫描电镜（sem)相比，透射电镜（tem)提供的 放大倍数 也相当高:透射电镜(tem)可以将样品放大5000万倍以上，而对于扫描电镜(sem)来说，限制在1-2百万倍之间。
