Edmund Optics Inc. 21mm Dia. Eyepiece Reticle, 10mm Scale/100 Div, 1X Mag. NT54-245

Scaled reticles are designed to allow direct measurement capability for many standard microscopes. Because reticles that have not been scaled for the objective power of the microscope require the use of conversion factors, adjusted reticle patterns increase efficiency and accuracy. These are designed for direct measuring capability when used with the appropriate objective power. Simply select the reticle corresponding to the desired objective power.Note: At powers other than specified, a conversion factor must be used.
