Add a cross-scale optical-glass reticle to a compatible microscope eyepiece with a 20 mm internal fitting diameter.

Add a scale reference to a compatible eyepiece

• ✅ View a scale in the eyepiece – The etched cross-scale provides a reference over the microscope view.
• ✅ Fit the selected diameter – The 20 mm disc suits an eyepiece designed to accept that reticle size.
• ✅ Prepare for calibrated comparison – The scale can be used after calibration with the appropriate microscope setup.

• Specifications: Optical glass; selected diameter 20 mm; cross-scale design.

• Package: One eyepiece reticle only; microscope and stage-calibration slide are not included.

Confirm the division spacing before purchase: the information lists both 0.01 and 0.05 mm. Calibrate against a suitable stage micrometer for each objective before measuring specimens.
