31 021200 EM Tec Au on C resolution standard 2 30 300nm small

Rave Scientific offers quality resolution standards which are essential tools for obtaining optimum resolution, settings, beam size and astigmatism correction on SEM, CD-SEMs, FESEMs, FIB, Microprobe, Auger and SIMS systems. The industry standards are:

  • Gold particles on a carbon substrate
  • Tin spheres on a carbon substrate.

Gold particles on carbon have rich features and provide excellent signal strength for secundary electron (SE) imaging. They are equally suitable for low voltage backscatter electron (BSE) imaging. The nearly perfect round tin spheres have an easy to recognize shape and can be used where gold is not tolerated. Multiple particle sizes are offered for different imaging applications. The carbon substrates are all 6mm in diameter and 2mm in height.


EM-Tec gold on carbon resolution standards


The gold particles on the gold on carbon resolution test specimens provide relatively sharp features, dispersed individual particles and excellent contrast against the carbon substrate. There are 4 different sizes of EM-Tec gold on carbon resolution test specimens available:


The EM-Tec resolution standards are available unmounted or ready mounted on popular SEM stubs. Select more info at the specific resolution test specimen to see the mounting options.

 

31 022100 Tin On Carbo10 medium EM-Tec tin on carbon resolution standards

Tin spheres on carbon provide an excellent test specimen to determine the resolution of SEM, FESEM, FIB, CD-SEM,  Microprobe, Auger and SIMS systems. The nearly perfect round spheres in various sizes are especially suitable for determining image quality, brights & contrast (grey levels), optimum probe size and astigmatism correction.  Tin on carbon is used where gold on carbon is not allowed in the SEM. The shape of the round spheres are easy to recognize and easier to use than gold on carbon. However, the overal signal level is lower than that of gold on carbon test specimens. There are two sizes of tin spheres resolution calibration  standards available:

  • EM-Tec 6 with Sn spheres ranging from 5nm – 30μm. This resolution standard covers a wide magnification range and is also useful for the medium and lower magnification range, starting at around 100x.  Also useful at lower kV ranges due to the larger spheres. Start at lower magnification and zoom in on the smaller spheres at (much) higher magnifications.
  • EM-Tec 7 with Sn spheres ranging from 10-100nm.  Excellent test specimen for high resolution SEMs and FESEMs with a nice smooth layer of Sn spheres. Use at 30,000x magnifications or higher.

The EM-Tec resolution standards are available unmounted or ready mounted on popular SEM stubs. Select more info at the specific resolution test specimen to see the mounting options.

 

EM Tec Multi and Combination SEM Standards EM-Tec Multi and Combination SEM Standards

The EM-Tec multi and combination standards offer up to 3 SEM test specimens and the M-10 silicon chip with 10µm calibration pattern on a single SEM specimen stub. The combination of different standards allows for moving quickly from one standard to the next. The multi SEM standards are ideal for a multi instrument environment and to quickly assess the performance of the SEM. The combination standard with tin spheres on a 10µm silicon grid are ideal for tabletop SEMs.


There are 6 different multi standards available. They are as follows:
