EM-Tec TS2 TEM test standard evaporated Pt/Ir RS-MN-33-001020

This 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.
