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.

Product information "BRESSER Stereo Microscope Science ETD-201 8-50x Trinocular Zoom with MikroCam SP 5.0 Microscope Camera"

Professional complete set for precise analyses and high-resolution image transmission: This powerful set combines the high-quality Science ETD-201 stereo microscope with the modern MikroCam SP 5MP camera. It is ideal for fine detail observations, sharp live images, and reliable documentation of your results.


The microscope in detail

The BRESSER Science ETD-201 is an optically high-quality incident and transmitted light stereo microscope.
It is suitable for use in medicine, agriculture and forestry, forensics, scientific research institutes and schools as well as for assembly and inspection of small components in precision mechanics and electronics.
The particularly wide base with object table and the exceptionally large height adjustment range allow the observation of larger objects. The instrument features LED incident and transmitted light illumination, which can be used individually or combined and each dimmed continuously. The incident light angle is particularly user-friendly adjustable and lockable. With interchangeable widefield eyepieces (WF10x) and a 6.25x stereo zoom objective (0.8x-5x), a continuous magnification range of 8x to 50x is realised. The click-stop zoom locks at predefined positions, so that magnifications can be exactly reproduced, e.g. for measurements on the microscope. The eyepieces have a field number of 22, allowing a visible field of view between 4.5 and 27.5 mm.

The eye distance and dioptre adjustment are individually adjustable. The trinocular microscope head can be rotated 360° and has two eyepiece tubes inclined at 45° as well as a separate, parfocally adjustable camera tube for connecting a C-Mount camera, or MikroCam, up to a 1/2" sensor size.

The microscope camera in detail

The BRESSER MikroCam SP cameras enable easy capturing of photos and videos with a microscope.

The modern CMOS sensors deliver brilliant colours with overall very low image noise and are thus the perfect solution for applications where natural colour reproduction is important. The included capture software offers numerous settings for capturing single images and videos. An integrated measurement function* allows measurement already in the live image. The included software supports the following languages: German, English, French, Polish, Turkish, Chinese.

The housing features a C-Mount connection thread. For use on devices with 23.2mm mounts, an optional variable reduction optic 0.5x (Art. No. 5914005) is available. For special applications, the camera can also be mounted on the integrated 1/4" tripod thread.

*Only in conjunction with an optional calibration slide (Art. No. 5916710 or 5916720)

BRESSER additional Objective 2x (ETD-201)
In some applications, it is desirable to increase the magnification by an additional 50x. With this 2x lens, you can use the Science ETD-201 at magnifications of 16 to 100x.. The working distance is reduced slightly. However, the depth of field is higher at the resulting magnification than when the magnification is increased by simply using another pair of eyepieces. A conversion lens is therefore the accessory of choice for magnifications greater than 50x. This additional lens is compatible with the following BRESSER microscopes: Science ETD 201 (5806200) DELIVERY CONTENT 1x additional lens (2x magnification)
