Our compact field microscopes are ideal for multi-purpose inspection applications. Internal roof prism ensures crisp, erect images. Each scope includes object adjustment with smooth, spiral twist focus ring. Clear acrylic base allows the instrument to rest directly on a flat object, while passing ambient light. A cutaway (two at 180° apart) in the clear base allows fine instruments to touch the object under inspection. The base can be removed for irregular objects. The base and bottom macro lens can be removed for added flexibility as an erect-image monocular scope for long distance requirements. C-mount Camera Adapter for video-imaging applications using 35X model fits with set-screws over eyepiece, while 25X version threads onto scope. Note that additional fine focus ring is only provided on macro lens with 45X and 40X models. Padded storage case included.
