FAQ - Frequently Asked Questions

I want to examine microorganisms such as lactic acid or photosynthetic bacteria – which microscope is suitable?

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.

Where can I find the Barlow lens?

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.

At higher magnifications the image is blurry or lacks contrast – what can I do?

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 Microscope Photo Adapter 23mm

Photo adapters are used to mount a camera on a microscope. SLR cameras work without their own objective. The magnification is made only by the microscope objectives. A specific T2-ring is necessary!With the BRESSER photo adapter 23 mm reflex cameras can be connected to microscopes with a eyepiece tube diameter of 23 mm. The camera is connected to the photo adapter via an optionally available T2 ring. The photo adapter is put into the eyepiece tube of the microscope instead of the eyepiece. Depending on type of construction and sensor or film size shadows may occur at the margins of the image.This photo adapter is compatible with the following BRESSER microscopes:Researcher Bino (5722100)Researcher Trinocular (5723100)Analyth Bino (5730000)BioScience Bino (5750500)Biolux ICD (5802000)Advance ICD (5804000)

BRESSER Darkfield Condenser dry (Infinity/TFM)

The BRESSER dark field condenser dry (Infitiy/TFM) directs the light to the side of the specimen. It increases the contrast of the specimen considerably, especially with highly transparent specimens. This type of illumination makes the observed object appear bright, against an almost black background. In this way, structures can be detected that are hardly visible in the bright field. The dark field condenser dry (Infitiy/TFM) is suitable for lenses that do not require oil immersion. FEATURES Contrast increase intensification of colors Details that are hardly visible in the brightfield can be recognized much better Suitable for lenses without oil immersion The condenser is compatible with the following BRESSER microscopes:5750900 Science TFM-3015760700 Science Infinity SCOPE OF DELIVERY 1x Dark Field Condenser

BRESSER Science TRM 301 Microscope

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.
