FAQ - Frequently Asked Questions

I want to examine microorganisms such as lactic acid or photosynthetic bacteria – which microscope is suitable?

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.

Where can I find the Barlow lens?

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.

At higher magnifications the image is blurry or lacks contrast – what can I do?

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.

BRESSER Darkfield Condenser dry (Infinity/TFM)

The BRESSER dark field condenser dry (Infitiy/TFM) directs the light to the side of the specimen. It increases the contrast of the specimen considerably, especially with highly transparent specimens. This type of illumination makes the observed object appear bright, against an almost black background. In this way, structures can be detected that are hardly visible in the bright field. The dark field condenser dry (Infitiy/TFM) is suitable for lenses that do not require oil immersion. FEATURES Contrast increase intensification of colors Details that are hardly visible in the brightfield can be recognized much better Suitable for lenses without oil immersion The condenser is compatible with the following BRESSER microscopes:5750900 Science TFM-3015760700 Science Infinity SCOPE OF DELIVERY 1x Dark Field Condenser
