1. High-precision calibration This 01-mm microscope object slider is designed for accurate calibration and measurement. Made from optical glass, it provides precise readings for your microscope and electronic eyepieces. 2. Stable and reliable The micrometer size measures 25 mm x 75 mm x 1 mm, offering a stable and reliable measurement platform. With a measurement range of 0.1 mm x 100 = 10 mm and 0.01 mm x 100 = 1 mm, it supports versatile applications. 3. Clear calibration points The microscope calibration ruler features two calibration points at 15 mm and 0.07 mm, delivering clear and accurate measurements. Each grid represents 0.01 mm or 0.1 mm for easy calibration. 4. Compatible with various devices Suitable for use with electronic eyepieces and microscope cameras, it can be integrated seamlessly into your existing setup. Improve the precision and accuracy of your microscope observations. Use scenarios - Calibrating magnification and stage movement when setting up new objectives or attaching a digital camera. - Verifying measurement accuracy for micrometer-scale samples in materials science or biology. - Routine calibration checks for high-magnification imaging to ensure consistent scale across sessions.
