Features and benefits

  • Observation tube includes an interpupillary adjustment of 48 - 75mm with an inclination of 30º and a compensation free trinocular head.
  • The quadruple nosepiece is reversed allowing unrestricted access to the specimen whilst the focussing turners and stage controls are conveniently positioned promoting fatigue free operation.
  • A pre-focus stop prevents slides and objectives from collision and damage and also allows for quick return to the focal point after the introduction of immersion oil.
