454 RK 820 stereomicroscope - Drawing: tilting possibility of eyepiece head (+40°; -40°) Another characteristic that distinguishes the RK 820 is the ergo nomic, person-adapted tilting ability of the eyepiece head which normally is 20° and can be varied by +/- 40°. The optical data of the possible options with the stereomicrosco pe are the following: ■ The eye distance can be adjusted between 47 and 120 mm thus offering an adaptable and viewer-friendly possibility. ■ The zoom system in the basic device has a zooming factor of 8 to 1 with a magnifying ratio of 0.425 to 3.4. The magnification of the system depends on the eyepiece, zoom, and supplementary lens magnification. ■ The system has 9.1 x and 13.7 x eyepieces whose magnifying ratio can be considerably increased by means of the 4.17 x and 6.25 x front objective lenses. By exchanging the eyepieces and front objective lenses the following magnifications can be achieved: Eyepieces Front objective Lenses System Magnifications 9.1 x 3.8 x - 31 x 9.1 x 4.17 x 16.1 x-129 x 9.1 x 6.25 x 23.8 x - 191 x 13.7 x - 5.7 x - 46 x 13.7 x 4.17 x 24.1 x-193 x 13.7 x 6.26 x 35.6 x - 285 x . The working distance of the RK 820 to the light table surface results from the different use of the front objective lenses. Supplementary Lenses Working Distance _ 100.0 mm 4.17 x 12.8 mm 6.25 x 3.3 mm RK 820 Stereomicroscope and accessoires
