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.

BRESSER MikroCam SF UHD Microscope Camera
The BRESSER MikroCam SF cameras are perfect for capturing high-quality photos and videos through a microscope. They make documenting and sharing your observations with others easy. Thanks to the high frame rate of the MikroCam SF series, you can record smooth and fluid videos. The built-in Sony sensors deliver excellent image quality, vibrant colours, and impressive dynamic range. The included software supports multiple languages, including German, English, French, Spanish, Italian, Polish, and Turkish. The MikroCamLabII software offers a wide range of features. Essential settings like exposure time and sensitivity can be adjusted automatically or manually. One of the standout features is focus stacking, which increases depth of field, as well as tools for creating mosaics and panoramas. Both functions can be used with a pre-recorded image series or directly in live view. With live focus stacking (EDF), the MikroCamLabII software can produce razor-sharp images in just minutes. As you adjust the focus on your microscope, the software automatically builds a perfectly sharp final image—no extra steps needed. This allows you to achieve stunning, high-quality results in no time.  The built-in measurement function* helps you determine dimensions or overlay a scale. With just a few clicks, you can measure distances, angles, or areas. Advanced tools even allow for precise measurements of circles (including area and radius) and complex polygons. Measurements can be performed on both captured images and live view. The MikroCamLabII software also includes powerful algorithms for automated image analysis, such as particle counting and surface evaluation. The camera body features a C-mount thread, making it compatible with microscopes from a variety of manufacturers. If you're unsure which MikroCam model is best suited for your microscope, we're happy to help. For devices with a 23.2 mm mount, an optional 0.5x reduction lens is available (Art. No. 5914015 (fixed), Art. No. 5914005 (variable)). For specialised applications, such as use with a C-mount lens, the camera can also be mounted using the built-in 1/4" tripod thread. *To calibrate the measurement function, a suitable measuring tool is required, such as Art. No. 5916710 or 5916720.

BRESSER Set Microscope Slides
Slides and cover glasses are an indispensable accessory which has also impact on the image quality. For most biological microscopes, the cover glass thickness is an important optical parameter, which is therefore included in the optical design and, if so, printed on the sleeve of every objective. You can usually see the number 0.17 which is the thickness in millimeters. For demanding applications in the laboratory, or for microphotography, using cover glasses with the desired thickness and high quality is necessary.The cover glasses included in the set are made of Boro 3.3 glass and are standardized to a thickness of 0.16-0.19mm. So they match the desired 0.17mm really good and give the best possible image quality. These Boro 3.3 cover glasses are pure white, without streaks and are pre-cleaned and ready to use. They are also especially suitable for fluorescence microscopy.The slides are made of soda lime glass, and have ground edges for safe handling. They have a matte field for writing on both sides (top and bottom). Slides and cover glasses are packed separately and in a vacuum sealed bag, containing moisture absorbent. They can be stored for a long time without loss of quality from hydrolysis and are easy to take out.
