Product Family Description

These glass reticles offer greater stability than film reticles which can bend, warp, and easily be damaged. Patterns are low reflection chrome deposition for high contrast and easy readability. Markings are on the outside of the reticle, so the scales are always in direct contact with the object under view. This provides optimum focus and accurate measurements. Our 21mm and 27mm diameter reticles for use with our 6X and 9X comparators and our 26mm and 35mm diameter reticles for use with our Peak Measuring Loupes and our Peak Illuminated Magnifiers. Please note the field of view specified for the magnifiers before selecting a magnifier/reticle combination. For example, the 5/8" (16mm) field of view for a 12X comparator may not be suitable for use with a reticle that has a ¾" (20mm) scale if the full scale is needed.
