Our portable and compact direct measuring field microscope can conveniently travel from the desktop to the job site for critical inspection and measurement. Each scope includes focus ring for crisp, clear images. Using the reticle focus adjustment, the 1/20mm scale reticle can be brought into sharp focus when superimposed on the internal image. Clear acrylic base allows the instrument to rest directly on a flat object, while passing ambient light. Two cutaways (180° apart) in the clear base allow fine instruments to touch the object under inspection. The base can be removed to accomodate irregular objects. The base and bottom macro lens can be removed for added flexibility as an erect-image 8X telescope for long distance requirements. Padded storage case included. Reticle: 2.5-0-2.5mm, 0.05mm incr. Note that focus ring is on the removable macro lens.
