Description
Comparison Microscope 20X WF Crosshair Mitutoyo Micrometer Fiber Optic Stage
This is a dual-head comparison microscope fitted with 20X wide-field (WF) eyepieces with crosshair reticles and a heavy precision black-anodized base. Each optical head has its own independent focus/tilt adjustment, allowing the operator to independently optimize both sides of the optical bridge. The stage platform is controlled by three Mitutoyo micrometer actuators for fine X-Y-Z positioning. The eyepieces are stamped "Germany," consistent with German optical manufacture. One objective lens (×1/10.07 f46.8) is installed; the second objective is not present and is not included with this instrument.

Applications
Comparison microscopes are specialized instruments designed to place two specimens side-by-side in a single optical field, allowing direct simultaneous visual comparison. They are widely used in forensic firearms examination (comparing bullet striations and tool marks), document and stamp examination (philately and questioned-document forensics), gemology, quality control, and materials analysis where two specimens must be directly compared at the same magnification. The dual independent optical heads and precision Mitutoyo micrometer stage controls on this instrument are well suited to applications requiring fine, repeatable lateral positioning of each specimen — a key requirement in forensic and metrology comparison work. The fiber optic under-stage illumination is a typical configuration for transmitted-light or oblique-light specimen examination. Instruments of this type and build quality, with German optics and Mitutoyo-branded stage micrometers, were commonly built for laboratory, government forensic, or precision quality-inspection applications.
This comparison microscope with 20X WF crosshair eyepieces has been inspected and is in good used condition with typical wear for a precision optical instrument of this age. The optics, dual independent head adjustments, and three Mitutoyo stage micrometers are all present and appear intact. One objective lens (×1/10.07 f46.8) is installed; the second objective is missing and is not included. The fiber optic under-stage illumination is present but the power supply for it is not included — buyers will need to source a compatible fiber optic illuminator to use that feature. The eyepieces are stamped 'Germany,' consistent with German optical manufacture. Please view our photo set and contact us if you have any questions.
