Precision calibration slide for optical measurement applications Key specifications Measuring range: X = 0.1mm x 100 = 10mm, Y = 0.1mm x 100 = 10mm. Calibration slide diameter: 19mm. Scale resolution: 1 DIV = 0.1 x 0.1mm. What this product does Provides a clear, evenly spaced grid for accurate two axis measurement under microscopes and inspection optics. Enables reliable calibration and verification of measurement systems across a 10mm by 10mm area. Why you need it Confirms and calibrates the scale of optical measurement setups to reduce measurement error. Delivers consistent reference markings so repeat measurements remain comparable over time. Supports faster setup and inspection workflows by making scale verification simple and precise. What makes it stand out Exact, uniform 0.1mm divisions across both X and Y axes for precise linear measurement. Compact 19mm diameter design matches instruments and eyepieces that accept standard 19mm slides. Constructed from materials for durable, stable performance and long service life. Features and compatibility Function: calibration and measurement reference for optical systems. Size: 19mm diameter slide with a usable measurement area of 10mm by 10mm. Material: manufactured from durable, stable materials to maintain scale integrity. Performance: fine 0.1mm grid ensures repeatable, lowuncertainty measurements. Practical use scenarios Laboratory microscopy: calibrate imaging systems and verify magnification scales before image capture. Quality control and inspection: measure small parts, PCB features, or surface patterns during production checks. Teaching and training: demonstrate measurement principles and provide a handson calibration reference for students. Simple to install, straightforward to read, and built for consistent performance, this calibration slide is suitable wherever precise optical measurement and routine calibration are required.
