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.

Warning notes
  • DANGER! Sharp-edged and pointed tools are often used with this device. Therefore, store the device and all accessories and tools in a place inaccessible to children. There is a RISK OF INJURY!
  • Immersion oil: Harmful if swallowed.
  • Immersion oil is very toxic to aquatic organisms with long-term effects.
  • In case of defects, contact your retailer or the manufacturer.
  • Disconnect damaged devices from the power supply or do not put them back into operation.
  • Small parts can be swallowed. Keep small parts out of reach of children, allow children to work with the device only under supervision.
  • Keep packaging materials away from children. There is a risk of suffocation.
  • There is a risk of pinching or abrasions from mechanical components like racks or drives.
  • Do not look directly into the light source. Adjust the brightness of the light source with the dimmer to a comfortable level.
  • Lay network or USB cables securely. There is a risk of tripping or property damage.

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.

BRESSER Microscope Science TRM 301 with MikroCamII 9MP 4K camera
The high-quality combination set consisting of the professional Science TRM-301 microscope and the powerful MikroCamII 4K 9MP is the ideal solution for demanding applications in the laboratory. It combines precise optics with modern camera technology perfect for research, teaching, and documentation at the highest level.The Microscope in DetailThe BRESSER Science TRM-301 is a trinocular transmitted light microscope of top class: Excellent image reproduction, good ergonomics, high stability, and an appealing design characterize it. As a fully usable laboratory microscope, it finds wide application in medicine, biology, agriculture, and industry. It is also highly recommended for the dedicated hobby microscopist as a ''microscope for life''.A particularly important feature of the TRM-301 is its ability for so-called Köhler illumination. Through this optimal specimen illumination, which is exceptionally bright, cool (specimen-friendly), uniform, glare-free, and high-contrast, the performance of the microscope optics is fully utilized. It therefore represents the standard in scientific work and microphotography. The Köhler illumination is adjustable with the fixed built-in field diaphragm and the height-adjustable and centering Abbe condenser (numerical aperture 1.25; with iris diaphragm).Of course, the TRM-301 also features the further equipment typical for high-quality microscopes: with a cross table that moves transversely and longitudinally with Nonius scales, ergonomic coaxial focusing drives (the fine drive achieves 200 µm/revolution), stepless lamp dimmer, plan achromatic objectives (4x, 10x, 40x, 100x-oil spring), 10x wide-field eyepieces (in 30° inclined eyepiece tubes), inter-pupillary distance and diopter adjustment, as well as a photo tube.FEATURES OF THE MICROSCOPETransmitted light microscopeHead type: TrinocularMagnification: 40x - 1000x2 eyepieces: both WF 10x (23mm)4 objectives: 4x, 10x, 40x, 100x oilObjective type: Plan achromaticCondenser: Abbe N.A. 1.25Illumination: 12V/30W halogen with dimmerSCOPE OF DELIVERY OF THE MICROSCOPEMicroscope2x eyepiece4x objectivecoaxial cross table with Nonius adjustmentImmersion oilDust coverPower supply 12V, 4AThe Microscope Camera in DetailWith the BRESSER MikroCamII 9MP 4K, 4K videos can be recorded at up to 30 fps (depending on the system used). Due to the global shutter, there are no image distortions during movement. The large image sensor (14.13 x 7.45 mm) provides a very large field of view.The very high light sensitivity of the Sony® IMX305 CMOS sensor enables very good image quality even in dark field or phase contrast.The BRESSER MikroCam Lab II software offers a variety of different functions, such as measurement in live image (calibration specimen required), mosaic creation, focus stacking (for increased depth of field). Furthermore, almost all automatic functions (exposure time, sensitivity, white balance, etc.) can also be set manually.The functions: mosaic and focus stacking (EDF) can be generated directly from the live image. This can save a lot of time.Even if you are not a professional, you will achieve quick success. To optimally use the mosaic function, a cross table is required.Due to the large sensor, the camera is not optimally suitable for every microscope. There may be edge shading (vignetting) in some cases. This shading is usually prevented by a 1x optic (Art. No. 5914001) that is screwed into the camera.This camera is not designed for the trinocular tube of the ETD-201. In this microscope, not the entire part of the field of view can be used.FEATURES OF THE MICROSCOPE CAMERAModern Sony® IMX305 sensor 14.13mm x 7.45 mm (1'')8.85 MP resolution (4096x2160 pixels)Many software functions, such as measurement, focus stacking (to overlay multiple recordings for increased depth of field), mosaic (to display larger fields of view)Image and video recording, including time-lapse function4K videos at up to 30 fpsVery large field of view in the microscopeHigh-quality metal housingGood compatibility with various microscopesC-Mount thread: for easy adaptability, also suitable for C-Mount objectives1/4'' tripod thread, e.g. for a photo tripodHigh-speed USB 3.0 connectionSYSTEM REQUIREMENTSWindows 10 or 11Intel i3, i5, i7 or i9 processor from 6th generation orAMD Ryzen processorOptical drive or internet connection for software downloadUSB 3.0, 3.1SCOPE OF DELIVERY OF THE MICROSCOPE CAMERACamera headUSB 3.0 cable23.2 mm adapter, 30 mm and 30.5 mmRecording and image processing software (for Windows)
