Ocular Micrometer

Short Description: A precision eyepiece graticule used with a stage micrometer to measure the size of microscopic specimens — essential for quantitative microscopy in biology, pathology, and materials science.

An Ocular Micrometer (Eyepiece Graticule) is a glass disc engraved with a fine scale that is inserted into the eyepiece of a microscope. When calibrated against a stage micrometer, it allows the user to accurately measure the dimensions of microscopic specimens directly in the field of view. It is an indispensable tool for any laboratory or educational institution performing quantitative microscopy, including cell sizing, particle measurement, and tissue analysis.

Key Features

• Precision-engraved scale on high-quality optical glass
• Fits standard microscope eyepieces (specify diameter when ordering)
• Used in conjunction with a stage micrometer for accurate calibration
• Durable, scratch-resistant glass disc
• Clear, high-contrast scale markings for easy reading
• Essential for quantitative and measurement microscopy
