Science folks and lab technicians, this microscope calibration ruler is exactly what you need for precise measurements under magnification!
The transparent PET film creates a durable, clear surface with precise grid patterns that won't interfere with your specimens.
With measuring ranges from 100-1000 μm for diameters and 0.01 mm to 0.2 mm for line widths, this ruler handles most common microscopy measurement needs. The 0.1 mm minimum scale gives you fine resolution for accurate readings, and the round coordinate layout makes it perfect for measuring circular specimens or working with polar coordinates. You can choose from three sizes - 75x45mm, 80x50mm, or 95x55mm - to fit different microscope stages and applications. The 0.1 mm thickness ensures it lies flat on your stage without affecting focus. Installation is simple - just place it on your microscope stage like a regular slide. The grid patterns appear bright and clear through your eyepieces, making measurements quick and consistent. Whether you're calibrating your microscope, measuring cell sizes, documenting specimen dimensions, or teaching students about microscopic measurement techniques, this tool is essential. The quality of the etching is precise, with sharp lines that won't fade or wear off with normal use. For research labs, educational institutions, quality control facilities, or serious hobbyists, this calibration slide provides that professional-level precision without the expensive price tag. Keep your measurements accurate and your equipment properly calibrated with this reliable, affordable laboratory essential that delivers results you can trust every time you use it!
