Calibration Accessories, Eyepieces & Reticles, and Stage Micrometers

Focusing Eyepiece:

Fits most standard monocular microscopes. Designed to accept 16 mm diameter reticle. Permits reticle image to be brought into sharp focus when super-imposed on the specimen image. The reticle is held in position by a screw on retaining ring. Easy to remove for cleaning or replacement. Magnification of 7X; Huygenian Design. Black anodized finish.

Eyepiece Reticles - Horizontal Micrometer:

16 or 21 mm diameter. Line 10 mm long divided into 100 equal parts.

Stage Micrometer with Micro-Coverglass, 100 µm Scale:

For use with transmitted light. Scale is 100µm long, divided into 50 equal parts. No certification available. These measuring standards may be used with all microscopes. The micrometer scale disc is mounted on a black anodized slide 3" x 1". The primary use for these micrometers is calibration of eyepiece reticles. The majority of microscopes are corrected to permit examination of specimens through a micro-coverglass by transmitted light and all stage micrometers are available in this form.

Adapter Rings: 

Black anodized aluminum rings of external diameters to fit the tubes of most eyepieces, with internal recess for one of the two standard reticle sizes. The rings may be fixed in the tube, cemented to the reticle, or used loose to permit easy cleaning. The field of view of the eyepiece is not normally impaired by these adapters.
