Product description

• The fluorescence microscope OBN 141 is a professional trinocular instrument with Infinity-corrected optics, designed for demanding fluorescence imaging and routine laboratory use.
• LED transmitted illumination (3 W) and LED epi‑fluorescence incident illumination (5 W).
• Professional Köhler illumination with adjustable field diaphragm and a centreable Abbe condenser (NA 1.25) with adjustable aperture diaphragm.
• Very large mechanical cross stage with ergonomic coaxial coarse and fine focusing knobs on both sides for rapid, precise sample positioning and focusing.
• Filter wheel configurable up to 6 positions; supplied with standard Blue/Green fluorescence filter.
• Modular design: supports a wide range of eyepieces, Infinity‑plan objectives, colour filters, darkfield condensers, butterfly tube, polarization and phase contrast units.
• Delivery includes centring objective for fluorescence alignment, dust cover, eye cups and multilingual user manual. C‑mount adapter required for camera connection (see accessories).

Applications

• Main application fields: haematology, urology, gynaecology, dermatology, pathology, microbiology and parasitology, immunology, wastewater treatment, oncology, entomology, veterinary clinics, water analysis, breweries.

Applications and samples

• Designed for translucent, thin, low‑contrast and challenging samples (e.g. immunofluorescence, FISH, DAPI staining).
