  • Adopt infinity optical system and modularization function design.

  • Infinity long W.D plan objectives, the field of view is widely and clear.

  • Wide-field plan eyepieces: field number Ф22mm.

  • Coaxial coarse/fine focus system, with tensional adjustable and up stop, minimum division of fine focusing: 2μm.

  • Polarizing unit can be move out or into optical path, polarizer and analyzer can be rotated from 0° to 360°.

  • Rotatable stage, 360° graduated in 1° increments, minimum retardation resolution 6undefined center adjustable and with tightener Stage vertical effective movement up to 30mm.

  • Wide voltage range power supply (85-265V 50/60Hz), 6V30W halogen lamp, brightness adjustable.

  • Trinocular can be observation for eyepieces and microphotography in 100% light flux, suits for low illuminance microphotography.


Characteristic:


  • Observation system

    Compensation observation tube: trinocular, single diopter adjustable, inclined 30°, 100% light transmission photography, can be connected to the camera.

    Eyepiece: WF10X wide field plan eyepiece, field Φ22mm, can provide expanse and smooth observation space. Another eyepiece is 10X dividing eyepiece used for proofreading the centre.

    Objective: Strain-free plan achromatic objective (no cover glass) and center adjustable.
