SEM finder grids

These new SEM grids are designed to aid in the identification and localisation of SEM specimens when placed on standard SEM stubs.
The SEMF1 has several features that are incorporated for easier location of the specimen and identification of areas of special interest

• Referring to the annular rim identifies north, south, east and west.
• The four quadrant markers are tapered towards the centre.
• 100 Radial sectors are easily identified by reference to decimal numbers in the annular rim and alphabet letters in the four quadrants.
• A matte surface on one side is for correct positioning - matte side up.

Type SEMF1

Referring to the annular rim identifies north, south, east and west. The four quadrant markers are tapered towards the centre. 100 Radial sectors are identified by reference to decimal numbers in the annular rim and alphabet letters in the four quadrants.

Type SEMF2

The larger cells are identified using numbers from 1 - 57. Each large cell is sub-divided into 4, making a total of 228 identifiable cells by reference to their number and geographical location.

Type SEMF3

25 cells are identified by reference to their alpha-numeric position. The large asymmetric cut-out feature in the rim enables the right view to be easily obtained when placing on a SEM stub.

Four quadrant markers tapered towards centre. 100 radial sectors.

Type Special

Finder grids for SEM; a valuable tool for analytical studies. The grids are available in 10mm diameter and they can be placed directly on the stub surface and used to identify the area of interest in which the studies are performed.
