The convenience and versatility of viewing a large picture at 10x magnification, then zooming continuously all the way to close-up detail at 40x magnification. Upright, unreversed 3-dimensional image remains in focus throughout zoom range. Optional eyepieces and auxiliary objectives expand magnification range and working distances.

Features top light with directional beam, bottom light with cool, long-life fluorescent illumination.

 

MAGNIFICATION

  • 1x to 4x Zoom

OPTICAL SYSTEM

  • Paired widefield 10x eyepieces are 45° inclined, with dual diopter adjustments, interpupillary adjustment from 55mm to 75mm. Accepts 23mm eyepiece reticle.

  • Achromatic, color corrected lenses.
  • Continuous magnification from 10x thru 40x. See specification chart for full magnification range available with use of optional auxiliary lenses

 

FOCUSING

  • Rack and pinion focusing with large dual focusing knobs with slip clutch to prevents damage to mechanism. Tension adjustment eliminates focus 'drift'.

 

ILLUMINATION

  • Top light is 12v 15 watt halogen, bi-pin with directional beam and rheostat control.
  • Bottom light is 110v 5 watt fluorescent for cool operation, greater light efficiency.
  • Base mounted light controls permit choice of top only, bottom only, or dual illumination.
