LAB LINE
The flexible laboratory assistant with infinity optical system and fixed, pre- centred Koehler illumination

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
Depending on the application, there is a choice of models with strong, continuously dimmable 3 W LED or 20 W halogen illumination (Philips)
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. You can select this adapter from the following model outfit list
Please find detailed information in the following model outfit list
