These reticles are scaled to match the power of the Objective, thus providing direct reading of the part to be measured. The accuracy of the measurement will be a function of both the true magnification of the Microscope Objective and the Calibration Reticle.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe 3X Microscope Calibration Reticle can be used with a 3X objective for direct reading measurements.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe 3X calibration reticle is useful for linear measurements and has an overall accuracy of 1μ over the 10mm length.
