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.
Product information "BRESSER Blank Slide with 1/100 mm scale"
Blank slides with 1/100 mm scale for your microscope are meant for calibration of measurements. They are used together with eyepiece micrometers or a measuring software (for cameras) to measure samples. This slide is suitable for biological microscopes or reflected light microscopes with high magnification (e.g. metallurgical microscopes). The scale is made by metal deposition on the glass surface of a standard (1x3 inch or 26x76mm) glass slide.
The slide is suitable for the calibration of the MikroCamLabII imaging software.
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.

The BRESSER TRM-301 is a trinocular biological microscope of first-class quality: This means excellent imaging, good ergonomy, high stability and a modern attractive design. It is a laboratory microscope, which permits an intensive use, e.g. in medicine, biology, agriculture and industry area. Also, we can recommend it to the engaged hobbyist as his "microscope for a lifetime".
A particular important feature of the TRM-301 is its ability for the Köhler illumination. This optimal illumination is bright, cool (going easy on the object), homogenous, reflex free and rich in contrast, so it makes the full use of the microscope optics. The Köhler illumination is standard for scientific research and microphotography. It is achieved with the fixed field diaphragm and the adjustable Abbe condenser (numerical aperture 1.25; with iris diaphragm). Naturally, the TRM-301 has the other features, which are typical for high-quality microscopes: lengthwise and cross moveable stage, ergonomic coaxial focusing knobs (fine focus: 200 µm / full turn), continous dimmer, planachromatic objectives (4x, 10x, 40x, 100x-oil retractable), 10x wide field eyepieces (mounted in 30° inclined eyepiece tubes), adjustment of eye relief, diopter adjustment and the phototube.

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.
A versatile combination set consisting of the Researcher Bino microscope and MikroCam SF5MP camera optimal for school, hobby, and profession. The robust Researcher Trino microscope impresses with its binocular view and allows for comfortable, precise work with clear, detailed images. Together with the MikroCam SF 5MP camera, which can be directly mounted on the trinocular connection, observations can be conveniently captured digitally, displayed on a computer, and saved for presentations or analyses ideal for use in education, leisure, or professional applications.The Microscope in DetailThe BRESSER Researcher Trino Microscope is the best-selling BRESSER transmitted light microscope in the mid-price range due to its unbeatable price-performance ratio. It already provides impressive insights into the microcosm. The microscope image is sharp and high-contrast. With its solid metal body and wide magnification range of 40x-1000x, based on 4 objectives and a (replaceable) pair of eyepieces, the BRESSER Researcher meets high demands. The 40x and 100x objectives are spring-loaded to prevent damage, and the 100x objective can be used for oil immersion microscopy (immersion oil is included). The bright LED illumination is adjustable with a dimmer. The Abbe condenser is height-adjustable and centring, and equipped with an iris diaphragm. For perfect sharpness adjustment, coarse and fine focus are available, and for precise positioning of the specimen, a coaxial stage. The 360° rotatable binocular head allows for individual adjustment of the inter-pupillary distance and diopter compensation between the observer's eyes.Instead of a binocular head, the Trino Researcher has a trinocular head. This allows the user to observe with both eyes while simultaneously connecting a camera or a PC eyepiece. Cameras from the MikroCam SP series and the MikrOkular Full HD can be used without additional adapters. The trinocular tube can be set to be parfocal with the eyepieces.For special contrast methods, the Researcher Microscope can be upgraded with a dark field condenser (dry or oil). The Researcher Trino is thus the most affordable trinocular microscope that offers this possibility.Examination Objects (Example):BloodRotifers / Wheel AnimalculesBacteriaParasitesPlants (thin sections)AlgaeSCOPE OF DELIVERY MICROSCOPETrinocular microscope1 pair of DIN eyepieces WF 10x with 23mm diameter4-fold objective turret4 DIN objectives: 4x/0.1, 10x/0.25, 40x/0.65, 100x/1.25 oilCondenserCross stage with Nonius scaleFine and coarse focusImmersion oilThe Microscope Camera in DetailThe BRESSER MikroCam SF cameras are excellent for capturing photos and videos with a microscope.
