Product Details

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

Features

  • The KERN OBF-1 and OBL-1 models are excellent and robust laboratory microscopes for all common routine applications.
  • Thanks to the simple Koehler illumination, the adjustable field diaphragm and a pre-centred and height adjustable Abbe condenser with adjustable aperture diaphragm, these microscopes produce impressive images in both bright and dark field applications.
  • The microscopes are equipped with wide field eyepieces, with achromatic, plan achromatic or infinity corrected E-plan objectives, depending on the model.
  • These binocular microscopes are equipped with diopter adjustment.
  • A trinocular head is optionally available, allowing a camera to be fitted.
  • A nosepiece for up to four objectives and a large stage are provided as standard.
  • The following optional accessories are available: A variety of eyepieces, objectives, a complete polarisation kit, a phase contrast unit, complete HBO and LED fluorescence kits and more.
  • 20W halogen illumination and a 3W LED alternative version are available for illumination.
  • One of the central features of this variable and simultaneously robust series of microscopes is the stable and precisely adjustable mechanism.
