Fluorescence Microscopes

Fluorescence Microscopes by KERN & SOHN – Targeted Imaging at the Molecular Level

Fluorescence microscopy is a powerful light microscopy technique used to visualize specific cell structures, molecules, or tissue components. It is based on the principle of fluorescence: fluorescent dyes (e.g. DAPI, FITC, GFP) bind to target molecules and are excited by short-wavelength light. The emitted light, at a longer wavelength, is made visible using specialized filter units.
Unlike conventional brightfield microscopy, fluorescence microscopy enables highly specific, contrast-rich imaging of cellular components – ideal for applications in cell biology, histology, microbiology and medical research.

KERN Fluorescence Microscopes – Functional, Reliable & Efficient

KERN fluorescence microscopes are developed for professional use in laboratories, teaching, and research. Depending on the model, they are equipped with a high-performance epi-fluorescence unit using either a classic mercury vapor lamp (HBO) or modern LED fluorescence illumination. These systems provide optimal excitation and illumination for fluorescence samples used in immunofluorescence, FISH, or DAPI staining.
Some models include a filter wheel or filter slider with up to six integrated fluorescence filters (e.g. B/G, UV, V). The number and type of filters vary depending on the model and scope of delivery.
The trinocular design allows for both visual observation and digital documentation. Optional digital microscope cameras can be connected to support seamless integration into digital workflows. Robust construction ensures long-term durability even in continuous use.

Frequently Asked Questions (FAQ) – Fluorescence Microscopes

1. What is a fluorescence microscope and how does it work?

A fluorescence microscope is a type of light microscope used to visualize fluorescent structures. Fluorophores bind to specific cellular targets and are excited by short-wavelength light (e.g. UV or blue). The resulting emission is captured via filters, allowing for high-resolution, selective imaging – ideal for diagnostics, research, and education.

2. Which fluorophores are supported by KERN microscopes?

The KERN OBN-14 and OCM-1 series support common fluorophores such as DAPI, FITC, GFP, TRITC, and more. The included filter blocks are optimized for these dyes and can be exchanged or expanded depending on the model.

3. What is the difference between a light microscope and a fluorescence microscope?

A light microscope uses transmitted light to make transparent samples visible. A fluorescence microscope, on the other hand, visualizes specifically labeled components through fluorescent dyes – perfect for molecular analysis and cellular research.

4. Are fluorescence microscopes suitable for education and training?

Yes. Due to their durability, ease of use, and camera compatibility, KERN fluorescence microscopes are ideal for use in universities, vocational schools, and training labs.

5. Can I digitally document fluorescence images?

Absolutely. All KERN models are equipped with a trinocular tube that allows for connection to a digital camera – enabling live image transfer, saving, and analysis. Perfect for lab reports, presentations, and documentation.
