Nylon Case, #36-286
Excellent for determining paper quality and ink absorption. Ideal for proofreaders. The transparent acrylic base rests directly on work for clear, close-up examinations. Base admits light to subject under view. 12X and 9X are Kellner-type, color-corrected, three-element lens systems. 6X model has a precision single-element DCX lens.
Twist focus with lock-ring for permanent setting. Contact reticle adapter ring on base accepts all 27mm diameter reticles. Since power increases as field of view decreases, the full reticle pattern of some crowded reticles will not be visible using the 12X comparator. Nylon case #36-286 is sold separately.
