The variable model for the flexible user in the  laboratory and vocational training

Features

  • The OBL series stands out through its infinity optical unit and is therefore ideally suited for all demanding transmitted illumination applications. The robust and ergonomic stand base guarantees safe and comfortable working.
  • The fixed, pre-centred and focusable 1.25 Abbe condenser with aperture diaphragm and field diaphragm gives you a simplified Koehler illumination, without having to move the centre.
  • The large mechanical stage and its specimen holder holds up to two samples at the same time and is quick and easy to focus using a coaxial coarse and fine focusing knob on both sides.
  • A large selection of eyepieces, objectives and colour filters as well as a darkfield condenser, a simple polarising unit, different phase contrast kits through to HBO and LED fluorescence units are available to you as accessories.
  • A protective dust cover, eye cups, as well as multi-lingual user instructions are included in the scope of delivery.
  • A C-mount adapter is required to connect a camera to the trinocular version.
