for life sciences applicationsfor researchfor biology

Overview
The OBN 135 is a modular transmitted-light compound microscope engineered for demanding medical and laboratory applications. It combines Koehler illumination, Infinity-corrected Plan optics and a large mechanical stage for precise sample handling.

Key features

• 3 W continuously dimmable LED transmitted-light illumination.
• Professional Koehler illumination with adjustable field diaphragm.
• Height-adjustable, centreable Abbe condenser with adjustable aperture diaphragm (NA 1.25).
• Large mechanical stage with ergonomic coaxial coarse and fine focusing knobs on both sides; fine drive resolution 0.002 mm.
• Infinity Plan objectives (standard: 4×, 10×, 20×, 40×, 100×) and 10× eyepieces (20 mm FOV); 5-position screw-in nosepiece.
• Wide range of modular accessories available: swing-out condenser, phase contrast units, darkfield condenser, simple polarising unit, Butterfly tube, fluorescence units, colour filters, camera adapters.
• Trinocular tube for camera integration (C-mount adapter required as accessory).

Note

• A C-mount adapter is required to connect a camera (accessory).

Applications

• Primary fields: haematology, urology, gynaecology, dermatology, pathology, microbiology, parasitology, immunology, oncology, entomology, veterinary practices, water analysis, breweries, sewage treatment facilities, medical laboratories, health authorities, training centres, universities.
• Typical samples: translucent, thin, low-contrast and challenging specimens (e.g. live mammalian cells, bacteria, tissue sections).
