A metal specimen-support grid provides physical openings for transmission electron microscopy. Its bars or surrounding frame support the specimen or a thin support film while leaving observation areas open.
Metal grid material, support-film type and compatibility with the specimen preparation method are selected together. A glass substrate is not part of this specimen-grid structure.
Wider bars provide more support but obscure more of the specimen. Larger openings expose more area but place greater demands on the specimen or supporting film. Mesh count alone does not define the clear opening: bar width also matters.
For labelled grids, record both the address and orientation. On an unlabelled regular lattice, record an identifiable reference before moving to another field; repeated cells may otherwise look identical.

Choose labelled finder or coordinate grids when recorded specimen regions need to be relocated. Record grid orientation and the local position within the labelled region.
A TEM support grid has physical openings. A chrome-on-glass reticle has a continuous optical substrate and serves a different observation or alignment role. Similar lattice geometry does not make the components interchangeable.
Mesh geometry, bar width, outer format, material and any support film determine the configuration. Coordinate marks add an address system without changing the fundamental specimen-support role.
The component definition identifies the metal grid and any support-film coating separately. Specimen preparation and the microscope holder remain separate parts of the workflow.
No. The pitch and bar width together determine the physical clear opening.
TEM coordinate grids identify specimen regions using a defined coordinate-marking layout.
Confirm labels, orientation and the visible coordinate map with the support structure and film.
Coordinate layout, labels, metal, mesh, support film and holder.
Coordinate marks identify regions. Dimensional measurements require a separately calibrated imaging scale.
