S21 Transmitted light stage micrometer with grouped graduations 5mm total length in 0.5mm divisions, 2mm section is further divided into 0.1mm divisions and final 0.2mm has 0.01mm divisions
These stage reticles S21 are intended for the routine calibration of eyepiece patterns, particularly when alternating between objectives on one microscope or when using the same reticle 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 76mm x25mm x 1.5mm thick. Line width: 0.0025mm Accuracy (overall): <0.002mm: Micrometer Scale 5mm/0.5mm, 2mm/0.1mm,0.2mm/0.01mm
