BRESSER Darkfield Condenser (oil type)

In addition to a diverse selection BRESSER Microscope also offers a wide range of accessories. The dark-field microscopy offers the bright-field microscopy is a special part. A gain is especially strong transparent preparations in contrast. The background is dark here, only the object is illuminated. The aperture is 0.85.This BRESSER Darkfield Condenser (dry) guides the light from the side to the preparation. The dark field condenser provides a strong contrast enhancement of the preparation, especially in highly transparent preparations. This condenser is compatible with the following BRESSER microscopes:Erudit DLX (5102000)Researcher Bino (5722100)Researcher Trino (5723100)TRM 301 (5760100)BioScience Trino (5750600)Science ADL 601 P (5770200)Science ADL 601 F (5770500)

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

In contrast to usual light, polarized light has a preferred vibration plane of the light waves. Polarized light lets be seen anisotropic objects, whose observable properties are depending on the direction, "in a new light": crystals, but also animal hairs, feathers, muscles, nerve fibres and vegetable cell walls, which have a preferred direction of its biomolecules, show structures now, which were hidden in the normal bright field image. Images made by polarized light are often characterized by a fantastic coloring. Polarization microscopes are used particularly in mineralogy, geology, biology and medicine. In order to change the object's direction in a controlled way, the Science MPO 401 has a round, center-adjustable and full rotatable object stage with degree scale. The illumination and observation unit encloses e. g. the halogen bulb lamp (20 W) with dimmer, the field diaphragm (used to achieve the Köhler illumination), the 360° rotatable polarizer (for the production of polarized light), centering implements for the objectives and the analyzer attachment (for the analysis of the polarized light). The analyzer attachment is meant for receiving the 360° rotatable analyzer and optional available sliders (Bertrand lens for conoscopy; quartz wedge, lambda plate and lambda/4 plate used in order to get special colour effects). The wide field eyepieces (WF10x), which are also optional available, are placed at the trinocular head with an inclination of 30°. They have eye relief adjustment as well as diopter adjustment. The images shown by them are bright, true colored, sharp and rich in details. Apart from the slips and eyepieces, which were mentioned above, the accessories of the MPO 401 contain a dividing eyepiece (WF10x), the Abbe condenser with iris diaphragm, special polarization objectives (4x, 10x, 40x retractable, 100x-oil retractable), filters (blue, ground glass) and immersion oil.

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 New BRESSER Science Infinity is the new top of the range of the biology microscope series by BRESSER. It is based on infinitely corrected planachromatic objective lenses with superb image quality. Because of the modern design and optics the installation of accessories is very simple and one has many options. The WF 10x eyepieces offer a large visual field of 22mm and are also suitable for spectacle wearers. For protection purposes the eyepieces are rubber coated. The interpupillary distance can be adjusted from ca. 55mm to 75mm. Dioptre adjustments are possible with both eyepieces.The bright and durable LED illumination is dimmable and also very practical for darkfield microscopy*.The Full Köhler illumination is adjustable with the built-in luminous-field diaphragm and the vertically and horizontally adjustable Abbe condenser (numerical aperture 1.25, with iris diaphragm). An imprint of the different possible magnifications on the condenser makes the adjustment of the iris diaphragm very fast and precise.Coaxial pinions drive the stage and focus which enables ergonomic operation of the microscope.The trinocular tube enables the direct attachment of a c-mount camera or MikroCam.SCOPE OF DELIVERYMicroscope with integrated LED illuminationplanachromatic objectives, infinity corrected (4x, 10x, 40x, 100x oil)2x eyepieces (WF 10x)Mains adapterManualImmersion oilDust cover*only with optional accessories
