S21 stage micrometers, grouped graduations (EMS)

These stage graticules are intended for the routine calibration of eyepiece patterns, particularly when alternating between objectives on one microscope, or when using the same graticule in different microscopes. Their robust construction makes them ideal for student use and for instructional purposes. The scale or grid is centred on a glass disc mounted in a black anodised aluminium slide 75mm x 24mm x 2mm thick. 

Two types are available:

• Transmitted light
• Reflected light, as is used with metallurgical microscopes
