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 MikroCamII Microscope Camera 12MP
The BRESSER MikroCamII microscope cameras help to make photos and videos with a microscope very easy. The modern Sony® CMOS sensors give brilliant colours with very low noise and is the perfect choice for any application where true natural colours are important. The included imaging software has multiple adjustments for the capture of still images and videos. The integrated measuring* routine allows for a measurement in the camera live image. The software can be operated in the following languages: German, English, French, Polish, Russian, Turkish, Chinese. The camera housing includes the c-mount adapter thread. For use with 23.2 mm adaptations, we recommend the optional, variable 0,5x reducer (item no. 5914005). For special applications, the camera can also be mounted using the 1/4'' camera tripod thread. The BRESSER MikroCamII are equipped with a USB 3.0 port, compared to the MikroCam SP. This enables up to 8 times faster data transfers to the PC compared with the USB 2.0 standard. The camera is able to deliver more than 25 frames per second (depending on resolution, exposure time and PC performance). This is especially important when observing live microorganisms. In addition to this, the camera is exceptionally sensitive. Even in low light conditions (high magnifications, contrast methods) the camera can be operated with short exposure times.

An optional 11" HDMI screen is available under item code 5914110 and can be mounted on the camera directly. It gives brilliant images with high contrast. Microscope images and video can now be stored on a SD card. The Sony Sensor gives excellent image quality and is very light sensitive. So this camera is recommended for low light contrast methods like darkfield or phase contrast. The autofocus enables the user to focus without using the mechanical focus wheel. When changing the objective, the focus will automatically be adjusted from the camera. The focus range from the "zero" position (which is the standard backfocus for C-Mount) up to 5,4 mm intrafocal to reach CS-Mount distance, and 10,6 mm extrafocal, to cover a wide range. In addition to the autofocus functionality, you can set the focus with the mouse or set a user defined focus range. The camera can be controlled with the included USB mouse directly through the on screen display. The on screen functionality now includes a measuring function as well, so the MikroCam Pro HDMI Autofocus upgrades your existing trinokular microscope to a fully equipped digital autofocus microscope.

BRESSER MikroCamII 5MP HIS Microscope Camera
The BRESSER MikroCamII 5MP HIS with the light sensitive and low-noise Sony® IMX264 sensor is perfectly suited for low light applications. The camera uses a global shutter, which captures moving objects without distortion. With sufficient lighting, the camera is also capable of ultra short exposures as low as 1/50.000 second. In this mode, the camera can virtually freeze fast moving objects. The BRESSER MikroCamLabII software includes a variety of useful functions, e.g. measuring in live mode (optional calibration slide needed), mosaic/stitching, focus stacking (for extended depth of field). All camera parameters (exposure time, gain, white balance) can be set manually. Mosaic and focus stacking can be done in live mode, which gives instant results even for unexperienced users. The method is also much faster than the normal procedure where a set of images is rendered afterwards. To use the mosaic function in live mode, a crosstable / mechanical desk is highly recommended to move the sample. The big camera sensor is not compatible with all microscope models. It might lead to vignetting (dark edges). To compensate this, a 1.0x optical adapter (item code 5914001) is recommended. This camera will not work with the ETD-201 stereo microscope as the microscope will illuminate only a part of the sensor. For this microscope, we recommend the model MikroCamII 12MP item code 5914912. SPECIFICATIONSmodern Sony® IMX264 sensor 8,45mm x 7,07 mm (2/3'')5 MP (2448x2048)software included, which contains measuring, focus stacking, mosaic / stitching for results with bigger fields or extended focus depthcapture images and video, incl. slow motion and timelapse1/4" tripod connectorPrecisely machined metal housingcompatible with numerous microscope modelswith c-mount connector, which is widely used.

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.
