Available on indent is a large range of graticules.
Delivery is usually three weeks.
Stage micrometers are normally mounted on standard size slides. When the graticule image is on the glass surface, this micrometer can be brought into direct contact with the specimen mounted thereon for measurement. It is rarely practical or economical,however, to mount specimen and scale together. For this reason, most measurements in microscopy are made by means of an eyepiece graticule, and the function of the calibration scale is to calibrate the system. The stage micrometer is protected by a cover glass which also duplicates the specimen's optical conditions.
