PRECISE CALIBRATION: The crosshair optical glass microscope slides feature accurate scale markings and calibrated rulers for precise measurement calibration under microscopes
MULTI-PURPOSE DESIGN: In addition to microscope calibration, the multifunction plate reticle can also be used for laser scanner calibration and as an optical measurement standard for quality control inspections.
DURABLE CONSTRUCTION: Made from high-quality hardened optical glass with non-fading engraved scales, the calibration slides are built to withstand regular laboratory usage and last for years of accurate measurements.
CLEAR MARKINGS: The etched centesimal scale markings are easy-to-read
