FAQs
1. What is the main difference between an inverted and an upright fluorescence microscope?
The primary difference lies in the orientation of the light path. Inverted microscopes have the light source above and the objectives below the specimen, ideal for observing specimens in culture dishes. Upright microscopes have the opposite configuration.
2. What are the key considerations when choosing an inverted fluorescence microscope?
Consider the required magnification, resolution, illumination type (LED or laser), number of fluorescence channels, sensitivity of the camera, and automation level. The budget and intended application are also crucial.
3. How important is the optical system in an inverted fluorescence microscope?
The optical system is critical for image quality. High-quality objectives with high numerical apertures are essential for achieving high resolution and clear images. Infinity-corrected optics provide superior image flatness.
4. What is the role of filter cubes in fluorescence microscopy?
Filter cubes selectively transmit specific wavelengths of light, crucial for exciting and detecting different fluorophores. A wider range of filter cubes increases the versatility of the microscope.
5. Are there any maintenance requirements for inverted fluorescence microscopes?
Regular cleaning of lenses and other optical components is essential. Calibration and servicing should be performed periodically by qualified technicians. Following manufacturer’s guidelines ensures optimal performance.
