BRESSER Phase contrast set (for 57-series)

To enhance contrast according to the refraction index and the thickness of the preparations. The phase contrast set contains four different irises, four different phase contrast objectives (10x, 20x, 40x, 100x oil) and a green color filter. A collimating eyepiece allows easy aligning. This method is especially suitable for non-stained, low contrast samples (epithelium cells, amoeba, white blood cells) and will also help with visibility of bacteria. Therefore it is used in cell culture and life science where color staining cannot be used. One position of the filter holder is free. Thus the phase contrast set can also be used as a brightfield condenser with iris diaphragm. This phase contrast set fits the Science Infinity (item No.: 5760700) 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.

The high-quality combination set consisting of the professional Science TRM-301 microscope and the powerful MikroCamII 20 MP 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 in microphotography. The Köhler illumination can be adjusted with the fixed built-in field diaphragm and the height-adjustable and centrable Abbe condenser (numerical aperture 1.25; with iris diaphragm).Of course, the TRM-301 also features the other typical equipment 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 DetailThe BRESSER MikroCamII 20 MP 1'' microscope camera is the professional solution for documentation at the microscope and features the largest sensor in the MikroCam series with a side length of 13.06 x 8.8 mm. This allows for large image fields to be captured. Depending on the microscope model, for example, the eyepiece field of view can be fully documented with this camera (for a 10x eyepiece / 22mm). Other cameras often capture less than 50% of the eyepiece field of view.The Sony IMX183 CMOS sensor has extremely low noise at high light sensitivity, making this camera also excellent for dark field or phase contrast shots.The MikroCam Lab II software offers a variety of different functions, such as measurement in live image (calibration specimen required), mosaic image creation, focus stacking (for increased depth of field). All automatic functions (exposure time, sensitivity, white balance, etc.) can also be set manually.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 corrected by a 1x optic (Art. No. 5914001), which is screwed into the camera.This camera is not designed for the trinocular tube of the ETD-201. With this microscope, only a small part of the image field can be used.FEATURES OF THE MICROSCOPE CAMERAHigh-quality metal housingMany software functions, such as measurement, focus stacking (to overlay multiple recordings for increased depth of field), mosaic (to display larger image fields)Image and video recording, including time-lapse functionGood compatibility with various microscopesHigh-speed USB 3.0 connectionModern Sony IMX183 sensor 13.06 x 8.8 mm (1'')1/4'' tripod thread, e.g. for a photo tripodC-Mount thread: for easy adaptability, also suitable for C-Mount objectivesSYSTEM 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)

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
