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.
BRESSERPlanachromat 20x - this DIN-Objectives are processed with the highest quality materials to enhance the image replication. Plan correction minimizes refocus between center and edge of field and is especially useful for imaging.
Fits the following models:
• Erudit DLX (5102000, 5102060) • Researcher Bino (5722100) • Researcher Trino(5723100) • Science TRM 301 (5760100) • BioScience Trino (5750600) • Science ADL 601 P (5770200) only for observations with transmitted illumination • Science MPO 401 (5780000)
Not recommended for models Erudit Basic Mono and Bino (5102100, 5102200) and Erudit MO (5110000) as those have a different parfocal length.
The BRESSER 0.5x reducing lens is designed to enlarge the image from a microscope camera. It increases the light intensity and therefore reduces the exposure time.
In the case of trinocular microscopes, the adapter usually enables the focus to be matched to the focus of the eyepiece.It is compatible with focusers with a 23.2 mm receptacle.
This adapter is specially designed for cameras with sensor sizes of 1/2'' or 1/3''. The connection is made via a 1'' C-mount thread.

This Full HD eyepiece camera lets you capture photos and videos directly through your microscope. The MikrOkular LF fits either in place of an eyepiece or into the microscope’s third tube. With the included adapter rings, it can be used with almost any microscope as an eyepiece replacement. If your microscope has a built-in C-mount camera connection, you’ll need the Microscope Photo Adapter 30.5mm / C-Mount (Article No.: 5942030).
The downloadable Windows software is user-friendly, making it ideal even for beginners. Along with image and video capture, it also includes a measurement function. Whether for hobbies, school, studies, or professional use, it’s a great tool for documentation.
Compared to the MikrOkular Full HD, the integrated reduction optics provide around seven times the image field area. The camera's field of view is approximately the same as that of a 10x eyepiece of a student microscope.

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 SF UHD 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 UHD camera, which can be directly mounted on the trinocular connection, observations can be conveniently captured digitally, displayed on a computer, and secured 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 interpupillary 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 PC eyepiece. Cameras from the MikroCam SP series and the MikrOkular Full HD can be used without further 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 table 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. This allows observations of objects to be easily documented and shared with others. The high frame rate of the MikroCam SF series enables the creation of videos with a smooth image flow. The built-in Sony sensors provide good image quality, colour reproduction, and dynamics.The included software supports the following languages: German, English, French, Spanish, Italian, Polish, Turkish.The MikroCamLabII software offers a wide range of functions. Essential functions (e.g., exposure time and sensitivity) can be controlled automatically or manually.Very convenient are the functions for so-called focus stacking (for high depth of field) and the creation of a mosaic or panorama. These two functions can be performed with a previously recorded image series or directly from the live view. The creation of sharp images using live focus stacking (EDF) is possible with the MikroCamLabII software in just a few minutes. While you focus on the microscope, the software gradually builds the finished, completely sharp result image without further intervention. This way, you get impressive, sharp image results in no time.The measurement function* included in the software helps you determine sizes or display a scale. You can measure distances, angles, or areas with just a few clicks. Extensive functions support you in measuring circles with area and radius or even complex polygons.Measurements can be performed in the captured image or in the live image. The MikroCamLabII software also has extensive algorithms for automated image analysis, e.g., for particle counting or area evaluation.The housing features a C-mount connection thread and can therefore be used with microscopes from various manufacturers. We are happy to advise you on which MikroCam is optimally suited for your microscope.For use on devices with a 23.2 mm receptacle, an optional 0.5x reducing optic (Art. No. 5914015 (fixed), Art. No. 5914005 (variable)) is available. For special applications, e.g., with a C-mount objective, the camera can also be mounted on the integrated 1/4" tripod thread.*A suitable measuring tool is required for calibrating the measurement function, e.g.: Art.
