Multi-image Calibration slide, PS20
Key Features
Multiple images and scales on a single stage slide with unique serial number, ideal for calibrating all image analysis systems. All features coordinate referenced to a datum point.
High definition 150mm scale in 0.1mm divisions with extended 0.5mm, 1.0mm and 5.0mm lines to allow calibrations in those increments too. Series of dots and crosses, at 10mm intervals, included for calibrations where these shapes are preferred. Supplied in polished wooden case.
Note: Part of PS150XO scale shown.
