Fluorescence Observation Brilliant and Affordable
Incorporating system versatility with outstanding Infinity corrected optics, the BK Series (replaces the JC Series) offers an affordable Fluorescece module to meet this specialized need.
- Filters - two cubes with single band excitors easily slide into place and combine with the HBO illuminator to deliver intense, high contrast images
- Optics - Infinity-corrected plan achromat lenses guaranty brilliant, color corrected, high contrast images
- Robust - all metal frame and focus mechanism endure high use while providing a stable platform minimizing vibration
- Mechanical Stage – Unique Locking Stage remains at focus even when pressed, saves time in changing specimens
- Versatile performance - multiple techniques available, including brightfield, polarization, phase contrast with slot built into condenser for slider and dark field
