EM-40

The EM-40 represents COXEM's latest addition to their expanding family of Tabletop SEMs.

Manufacturer

COXEM

COXEM manufactures and provides Scanning Electron Microscope (SEM), the most widely used platform technology in Nano- Metrology of Nano-scale. As a partner of Nano-fusion technology that changes industrial condition in 21 century, COXEM tries to provide the best quality service. SEM is the precision instrument, can be used for analysing the shapes or constituents of microstructure materials in quantitative and qualitative. SEM is an essential instrument for development of basic science and an indispensable infra for technical innovation, used in chemistry, biology, material science as well as nano-materials and nano-biology.

CN Tech are the exclusive Coxem distributor for:

United Kingdom and Republic of Ireland.

Overview

Building on the success of the EM-30 line of Tabletop SEMs, the EM-40 includes a host of features you would expect to find only on full-sized, more expensive SEMs. The EM-40 has ultra-fast 5th-generation signal processing technology and high-quality imaging at frame rates of up to 13 fps. There are four imaging modes (fast, slow, ultra fast, and photo) which allows the user to choose the image quality and speed that best fits their application. The EM-40 has a magnification range of 50 – 150,000x with large depth of field and accelerating voltages from 1 kV to 30kV, selectable in 1 kV steps. These, coupled with 4 user-selectable apertures, assure optimum conditions for high-quality imaging, every time. A new 3-axis motorised stage accepts samples up to 55mm in diameter, with a maximum height of 37mm, while the rotary and turbo molecular pumps will have you going from loading to imaging in under 3 minutes.

New Software: NanoStation5

Powered by NanoStation5 software, the EM-40 includes a suite of automated functions that simplify operation and help novice users achieve consistent results. Navigation View (including a built-in digital camera) allows the user to quickly move between Macro, Micro, and Nano viewing modes, making it easy to find your area of interest, even on multiple sample stubs. Equipped with an SE and a 4 quadrant BSE detector, the EM-40 allows the operator to view either detector individually, side-by-side, or as a composite image for a better understanding of chemistry and microstructure.
