Product Family Description

  • Designed for 1X Objective Power
  • Concentric Circle Pattern
  • B270 Substrate

Reticles are clear glass discs marked with scales or patterns, which fit into microscope eyepieces at the internal real image plane. This is the intermediate image of the specimen/object under inspection produced by the objective lens of the microscope. By placing the reticle at this position, the scale/pattern is superimposed on the image and both are in simultaneous focus. These reticles are all designed for an objective power of 1X. They are numbered 1-10, with dashed circle at 5mm and a 12.5mm crossline.
