This allows the graticule to be brought into sharp focus when superimposed on the object image, which is often difficult to achieve with fixed focus eyepieces. The graticule is held by a screw-on retaining ring and is easily removed for cleaning or replacement for another pattern.<br \/>\nComposed of a convex lens and an achromatic lens. The image plane is below the lens elements. The use of an achromatic lens provides a larger field of view, better color correction and substantial eye relief.
