KERN Fluorescence Microscope - OBN 141 - Trinocular - Illumination (transmitted) LED - Objectives 4x,10x,20x,40x,100x + FREE C-mount adapter
KERN OBN 141
The OBN 141 is a fluorescence microscope from the OBN-14 series. It combines a stable build with high quality optics, making it reliable for advanced fluorescence applications.
It uses a 3 W LED for transmitted light and a 5 W LED epi fluorescence unit for incident light. The Koehler illumination system has an adjustable field diaphragm and a 1.25 Abbe condenser that can be centred and adjusted with an aperture diaphragm for precise light control.
The large mechanical stage moves smoothly and is easy to handle using coaxial coarse and fine focus knobs on both sides. A filter wheel with up to six slots is included and fitted with B and G fluorescence filters.
The modular system allows the microscope to be extended with accessories such as eyepieces, objectives, colour filters, darkfield condensers, a butterfly tube, polarising units, and phase contrast units.
The OBN 141 is supplied with a free OBB-A1515 camera adapter. This C-mount 0.5x adapter with adjustable focus connects a microscope camera to the trinocular tube for easy image capture. A centring objective for fluorescence adjustment, dust cover, eye cups, and multilingual instructions are also included.
