We have developed this series especially for general applications with the phase contrast method. The stable and modular construction system of the OBL series also guarantees many other possibilities. It features powerful and infinitely dimmable 3W LED illumination. A special, height-focussable and fixed pre-centred phase contrast condenser, along with the light field diaphragm, allows you to simplify Köhler illumination and achieve powerful phase contrast imaging of your sample.

The large mechanical stage and its specimen holder can hold up to two specimens simultaneously and focus quickly and easily thanks to a coaxial coarse and fine drive on both sides. A large selection of eyepieces, objectives, and color filters, along with a simple polarization unit and other phase contrast units, are available as accessories.

A dust cover, eyecups, and a multilingual operating manual are included in the scope of delivery. A C-mount adapter is required to connect a camera.
