S20 stage micrometers, dual metric and imperial scales (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 lightReflected light, as is used with metallurgical microscopesSpecifications:Stage Micrometer for transmitted light with Metric/Imperial Double Scales. 2mm scale in 0.01mm divisions (10µm) and 0.1 inch scale in 0.0005 inch divisions.Line Thickness - 0.002mm ±0.001mmGlass Type and Thickness - B270 1mm thickScale Length Tolerance - ±0.0015mmMount - Black Anodised Aluminium Slide (76mm x 25mm x 1.5mm)Divisional Marker Lengths - 0.175mm...
