MUHWA 0.1mm Feet-Shaped Eyepiece Graticule — 19mm Ocular Reticle for Microscope Measurement and Particle Sizing
MUHWA 0.1mm feet-shaped eyepiece graticule is a precision chrome-on-glass ocular reticle designed for measuring, counting, and sizing microscopic specimens directly through the microscope eyepiece. The distinctive feet-shaped pattern consists of paired markings at 0.1mm intervals, ideal for measuring irregular particles, fiber diameters, cell dimensions, and non-uniform specimens. The 19mm diameter format fits standard 10x and 15x wide-field eyepieces from major manufacturers. Chrome-deposited pattern on optical glass provides high contrast under bright-field, phase-contrast, and polarized light. When calibrated against a stage micrometer, this graticule enables direct real-time measurements in micrometers.
Key Features
- 0.1mm Feet-Shaped Pattern — Unique paired-marking design for measuring irregular shapes, fibers, particles, and biological specimens. Each foot pair provides a reference interval for sizing and counting.
- 19mm Standard Diameter — Compatible with most wide-field 10x and 15x eyepieces from Olympus, Nikon, Zeiss, Leica, and Motic microscopes.
- Chrome-Deposited on Optical Glass — High-contrast, durable chrome pattern with sharp markings. Resistant to fading under normal use.
- Calibratable Reference — Use with a 0.01mm stage micrometer to establish true measurement values at every objective magnification.

Frequently Asked Questions
Q: How do I install the graticule in my eyepiece?
A: Unscrew the lower lens assembly of your eyepiece. Place the graticule (pattern side down) on the internal shelf. Reassemble the eyepiece and focus using the diopter adjustment ring.
Q: Will this fit my microscope?
A: Most 10x and 15x wide-field eyepieces accept 19mm diameter reticles. Check your microscope manual or measure your eyepiece shelf diameter.
Q: How do I calibrate the graticule?
A: Place a 0.01mm stage micrometer on the stage. Count how many graticule divisions correspond to a known distance on the micrometer. Calculate the calibration factor for each objective and record.
