FAQ - Frequently Asked Questions

For this application we recommend the BRESSER Erudit DLX 40-1000x microscope in combination with a USB camera, e.g. the BRESSER MikroCam 1.3 MP. This solution offers better image quality and flexibility than a simple LCD microscope.

If you want to identify bacteria, it is usually more useful to create a culture. Microscopes are generally only sufficient to determine whether the bacteria are, for example, spherical or rod-shaped.
The Barlow lens is already installed in the eyepiece tube on many devices. It can be pulled out at the upper ridge to use the zoom function.
Possible causes:
 
  • Sample too thick / unsuitable: Use thin samples or fixed smears.
  • No cover glass or incorrect thickness: Objectives are optimized for cover glasses.
  • Condenser incorrectly adjusted: Do not open the diaphragm too far – otherwise contrast will be low.
  • Magnification too high: Rule of thumb: maximum 1000 × objective aperture. Example: With a 40x objective with aperture 0.65, the limit is about 650x.
