Overview

Rave Scientific offers high quality TEM resolution, calibration and test standards to optimize the performance of your TEM. Manufactured from specially selected materials to produce reliable and field proven TEM test standards which are commonly used. The TEM standards are using either copper, gold or aluminum square mesh grids. The TEM performance test, calibration or resolution check can be performed where the materials span the opening in the carbon film or between the grid bars.

EM-Tec TR1 TEM resolution standard fine gold particle

rs mn 33 001070The finely dispersed thin gold particles on a carbon film provide an excellent high resolution TEM standard. The gold particle size distribution is normally in the 2nm to 9nm range. Image quality, magnification and instrument stability are readily determined. For resolution assessment, this standard offers a choice of crystalline orientation on static or low tilt stages. The thickness of the crystals can be calculated form the projected shape of the gold crystal. The background noise from the structure of the carbon support film helps in determining the operating transfer function.

EM-Tec TR2 TEM resolution standard graphitised carbon black

rs mn 33 001080Graphitised carbon black provides a stable resolution standard for TEM resolution testing. The graphitised carbon black particles exhibit lattice planes following the contours of the particles. Lattice plane distance is 0.34nm. Supplied on a holey carbon film on a copper TEM grid

EM-Tec TS1 TEM test standard perforated carbon film

rs mn 33 001010The perforated (holey) carbon film is used for TEM performance checks, especially astigmatism correction. Best used at magnifications up to 250,000x. The perforated carbon film is mounted on a 400 mesh Cu TEM grid.

EM-Tec TS2 TEM test standard evaporated Pt/Ir

rs mn 33 001020This TEM test standard provides Platinum/Iridium particles evaporated on a holey carbon film. The holes in the carbon film are useful for focussing and astigmatism corrections. The small crystals of Pt/Ir provide excellent high contrast particles for resolution checks using the point separation test. Provided on a 300 mesh Cu TEM grid.

EM-Tec TS3 TEM combined test specimen standard

rs mn 33 001030The combined test specimen standard provides a 3 in 1 method for testing the performance of the TEM. The combined test specimen consists of graphitised carbon particles on a holey carbon which are shadowed with gold. Combines astigmatism test using perforated carbon film with resolution tests using graphitised carbon black and fine gold particles. The evaporated gold forms small polycrystalline islands in which lattice fringes can be resolved. The combined test specimen can also be used for contamination measurements by noting the carbon depositing rate within the holes of the gold film. Mounted on a 300 mesh copper TEM grid.

EM-Tec TC1 TEM calibration standard oriented gold crystal

rs mn 33 001040Oriented gold crystal provides plane spacing of 0.102, 0.143 and 0.204nm. Used for checking resolution, image quality, magnification and instrument stability in high resolution TEMs. The single oriented gold crystals produces a characteristic diffraction patterns. When the TEM is correctly setup, it should resolve the 0.102 nm (100 plane) planar spacing, 0.143 nm (220 plane) and the 0.204nm (200 plane). Since these are physical constants they can also be used for magnification calibration. Mounted on a 400 mesh Au TEM grid.

EM-Tec TC2 TEM calibration standard evaporated Al

rs mn 33 001050The aluminum film of around 30nm is used for calculating the value of the camera length. The small Al crystals provide a well defined diffraction pattern. The Al film is evaporated on a holey carbon on a 400 mesh Cu TEM grid.

EM-Tec TC3 TEM EDX calibration standard Cu foil on Al grid

rs mn 33 001060A thin copper foil on an aluminum TEM grid provides well defined and separated lines of Al (K-line) and Cu (K- and L-lines) in an EDX spectrum. These lines can be used to calibrate the EDX spectrometer and to asses EDX detector efficiency. The carbon coated 60nm Cu foil is mounted on a 200 mesh aluminium TEM grid.
