Instructions For Mounting Reticles In Eyepieces


Finding the correct position in the eyepiece for the reticle is usually quite simple. In most occulars a field stop is located in the occulars focal plane.

To locate this field stop unscrew the bottom retainer of the eyepiece. Remove the retaining ring and existing reticle if applicable.

Carefully clean the new reticle and insert it against the field stop. Be sure to position the reticle so that the image is viewed correctly through the eyepiece.

Install the retaining ring against the reticle snugly. Before screwing the eyepiece back together ensure that the reticle is free from dust or debris.

The reticle can be focused in the normal manner by turning the top of the eyepiece. Some eyepieces do not require a retaining ring, and still others require cementing the reticle in position. In any instance the general instructions above apply.

Some eyepieces are not equipped with field stops. In this case you will need to contact the microscope manufacturer and ask that they supply you with the proper insert in conjunction with your particular microscope.
