Application Notes & Technical Insights

📘 Fluorescence Imaging with Axiocam 807 Mono

The Axiocam 807 Mono camera provides exceptional sensitivity for low-light fluorescence applications. To maximize performance:

  • Use low excitation intensity to reduce phototoxic effects.
  • Activate the cooling system to reduce dark current noise during long exposures.
  • Apply flat-field correction in software to eliminate uneven illumination artifacts.

🔍 Image Stitching for Large Field of View

For biological and materials research, stitching allows you to observe wide samples with full detail. Recommendations include:

  • Use a motorized stage for precise tile acquisition.
  • Maintain 10–15% overlap between adjacent fields.
  • Employ ZEN software for stitching with shading correction enabled.

🔬 Live Cell Imaging Guidelines

Live cell workflows demand environmental control and sensitivity to prevent cell stress:

  • Use incubation chambers to maintain 37°C, 5% CO₂, and humidity.
  • Utilize minimal exposure times, even in time-lapse sequences.
  • Optimize autofocusing methods to reduce sample disturbance.

⚙️ Technical Maintenance & Calibration

Ensure consistent, high-quality imaging by performing regular maintenance:

  • Clean objectives with ZEISS-approved lens cleaning kits.
  • Calibrate each objective using a micrometer slide for accurate scaling.
  • Keep optics dry and dust-free by using silica gel in storage cabinets.

🧠 Troubleshooting & Optimization

If imaging performance is degraded:

  • Noise Issues: Reduce gain, increase averaging, or use longer exposure with cooling.
  • Vignetting: Ensure proper condenser and field diaphragm alignment.
  • Lag in Live Preview: Close background apps, check USB bandwidth, and reduce preview resolution.
