Reticles (Ocular Micrometers) &
Stage Micrometers

100's of standard designs. Custom designs available.

A Reticle, also called an Ocular Micrometer or Graticule, is a glass disk with a pattern on it that fits inside a microscope eyepiece (ocular). They are typically used for specimen measurement, but can have other uses as well.

A Stage Micrometer is used to calibrate the reticle.
