20X Eyepieces (pair) for use with XTL Microscopes. These eyepieces double the magnification to the observer without any impact on working distance. The table below shows the effect on the field of view and magnification (and working distance) of adding eyepieces and auxiliary objectives: Specification of auxiliary objectives and eyepieces – XTL-101/2/3 Eyepiece\Objective Main body 0.5X objective 0.75X objective 1.5X objective 2X objective 0.7x-4.5x 0.35x-2.10x 0.49x-3.15x 1.05x-6.3x 1.4x-8.4x 10x (std) Total magnification 7x-45x 3.5x-22.5x 5.3x-31.5x 10.6x-63x 14x-90x Diameter of visual field(mm) 31-5.2 62x-9.6x 38-6.4 19-3.2 14.3-2.4 15x Total magnification 10.5x-63x 5.3x-31.5x 7.9x-47.5x 15.8x-94.6x 21x-126x Diameter of visual field(mm) 21.4-3.6 42.8-7.2 28.5-4.8 14.2-2.4 10.7-1.8 20x Total magnification 14x-84x 7x-42x 10.6x-33x 21.2x-126x 28x-168x Diameter of visual field(mm) 17.1-2.9 34.3-5.7 22.9-3.8 11.4-1.9 8.6-1.4 25x Total magnification 17.5x-105x 8.8x-52.5x 13.1x-78.8x 26.3x-157.5x 35x-220x Diameter of visual field(mm) 12.9-2.1 25.7-4 17.1-2.9 8.6-1.4 6.4-1.1 Working Distance(mm) 88 137 103 48 25
