Micrometer Disc Reticle
Micrometer Disc Reticle (Product Code: SLE/M/67) is a 25 mm straight-line eyepiece reticle carrying a 5 mm scale divided into 100 parts, used inside a stereomicroscope eyepiece to measure specimens while they are being viewed. It fits inside most stereomicroscope eyepieces and comes with a retainer ring that holds the disc in position. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as one of the measuring accessories it offers as a laboratory instruments supplier in India.

What Is the Micrometer Disc Reticle Used For?
A reticle turns a stereo microscope into a measuring instrument. Students can record the body length of insects and larvae, the size of seeds, fish scales or sand grains, and the spacing of leaf features, then compare samples in ecology or genetics practicals. Because the scale sits in the eyepiece, it stays superimposed on the specimen at every position, which is quicker than placing a ruler beside the object and far more precise at magnification.
The divisions must be calibrated before readings mean anything. Put a stage micrometer slide under the objective, line up the two scales and work out the real distance that one reticle division covers at that magnification; repeat for every zoom or objective setting you use. When installing the disc, handle it by its edges, seat it in the eyepiece, secure it with the retainer ring and adjust the eyepiece focus until the scale looks sharp.
What to Specify When Ordering
- Your stereomicroscope model, so the fit of the 25 mm disc can be confirmed
- Number of reticles, usually one per measuring eyepiece
- Whether a stage micrometer slide is needed for calibration

Frequently Asked Questions
What scale does the Micrometer Disc Reticle have?
The Micrometer Disc Reticle carries a straight-line 5 mm scale divided into 100 divisions on a disc 25 mm in diameter. The real size each division represents depends on the magnification, so the scale is calibrated against a stage micrometer.
Will the Micrometer Disc Reticle fit my eyepiece?
The Micrometer Disc Reticle fits inside most stereomicroscope eyepieces that accept a 25 mm disc. To be certain, send your microscope model or the eyepiece details through the contact page and we will confirm before you order.
How is the Micrometer Disc Reticle held in the eyepiece?
The Micrometer Disc Reticle comes with a retainer ring that secures it inside the eyepiece. Once fitted, the scale stays fixed in the field of view, and the eyepiece focus is adjusted until the lines appear sharp.
How do I calibrate the Micrometer Disc Reticle?
Calibrate the Micrometer Disc Reticle by placing a stage micrometer slide under the microscope, aligning both scales and noting how many reticle divisions match a known distance. Calculate the value of one division and repeat the process for each magnification or zoom setting.
Who supplies the Micrometer Disc Reticle?
Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India supplies the Micrometer Disc Reticle to schools, colleges, research laboratories, dealers and importers in India and international markets, together with stage micrometer slides and stereo microscopes.
