BRESSER Phase Contrast Set for Science Infinity Microscope

The BRESSER Biolux NV comes with a wide range of accessories and is an ideal beginners' microscope. A unique feature of these models, the Barlow zoom system is inside the eyepiece tubes: With the barlow lens the magnification can be  varied by a factor of 2 in visual observation. This feature, together with 3 objectives and 2 interchangeable wide field eyepieces gives a magnification range from 20x to 1280x. With the mechanical desk you can move your sample precisely even when observing at high magnifications. For optimal illumination a variable LED for transmitted and incident light together with a filter wheel gives the ideal light for all samples. Light from above is especially imortant to observe non transparent samples like leaves, small insects and much more. This makes microscopy for beginners very easy! The power is supplied by batteries (3x AA). A dust cover, 5 prepared slides and 5 blank slides and cover slips are included for making your own samples. With the included HD camera you can observe your samples on the computer screen, and capture images and video with the included Windows software. The software is compatible with Windows 10 and 11. With this camera, you can always document your interesting observations and share them with others.

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 NEXCOPE NE910 microscope offers excellent optical performance and ease of use, and is ideal for scientific tasks. It is the perfect laboratory microscope for life sciences, histology, microbiology etc., and comes with an attractive price tag. LENSES The planachromatic infinity lenses ensure a flat field of view. Together with the swing top condensor (NA 0.9/0.25), the lenses deliver a high contrast and high resolution over the entire visible spectrum. The nosepiece has six positions and is equipped with four lenses as standard (4x, 10x, 20x, 40x, 100x oil). These feature an M25 thread and a parfocal length of 60 mm. The 40x lens has a spring-loaded protection mechanism. EYEPIECES The eyepieces’ large 25 mm field of view allows you to view a very wide area. The high eyepiece head is ideal for spectacle wearers. A rubber edge provides protection upon eye contact. A dioptre compensation of -5 to +5 can be set individually for each eyepiece. The interpupillary distance can be adjusted between 47 mm and 78 mm. ILLUMINATION The powerful 3 W LED has an adjustable brightness and provides optimal illumination with excellent colour reproduction. The colour temperature stays constant when the light is dimmed. The light is equipped with an Eco sensor that switches the light off when it is not in use. The condensor with an iris diaphragm and swing top is adjustable and provides Köhler illumination together with the light source, which is also equipped with an iris diaphragm. Markings on the knurled ring allow you to adjust the aperture to the chosen lens at any time. The auxiliary lens can be pulled out to quickly switch the aperture from 0.9 to 0.25, e.g. to examine the specimen. This enables efficient and reproducible results. Frosted and neutral density filters can be moved into the beam path with a button press and provide optimal illumination/brightness adjustment without operating the dimmer. MECHANICS The XY stage is moved via a combination of a toothed rack drive and a wire rope hoist. This enables exact positioning for high magnifications. The height of the coaxial control knobs can be adjusted to ensure an ergonomic setup. In addition to the coarse focus, the fine focus helps to render a very sharp image of the object. A full turn of the fine focus moves the table up/down by 0.2 mm. The fine focus can be adjusted with one finger on the right-hand side. The XY stage and focus can be operated simultaneously with one hand. The table height limit helps to protect the specimens and optimize workflows. The large (152x190mm) specimen stage with an impact-resistant Gorilla Glass™ inlay is suitable for all laboratory tasks. It is also resistant to liquids and easy to clean. The friction of the coarse focus can be adjusted to the user. The fine focus knobs are held in place magnetically and can be installed on the left or right side as desired. CAMERA CONNECTION The NEXCOPE NE910 is specially designed for use with c-mount cameras. You can choose from two different adapters, depending on the sensor size: 0.5x c-mount adapter for sensor sizes up to 2/3” 1x c-mount adapter for sensor sizes of 1” As the adapter can be adjusted, the camera image can be matched parfocally to the eyepieces. The beam splitter features three different modes: Eyepieces 100% / Camera tube 0% Eyepieces 50% / Camera tube 50% Eyepieces 0% / Camera tube 100% ACCESSORIES (optional) Lenses: 2x, 60x,Dark field condenser, dry or oil Phase contrast set Differential interference contrast (DIC) Reflected light unit Epi-fluorescence unit Polarisation set FEATURES Professional upright research microscope 6x nosepiece, tilted backwards Lens type: Planachromatic, infinity (60 mm parfocal length, M25) Precise and ergonomic mechanics Outstanding expandability for all common contrasting techniques, as well as fluorescence Bright LED illumination Eco mode Köhler illumination (full Köhler) Integrated matte filter WHAT'S INCLUDED Microscope stand with 6x nosepiece, equipped with four planachromatic lenses (4x, 10x, 20x, 40x, 100x oil) One pair of 10x eyepieces (field of view: 25 mm, Plug-in diameter: 30 mm) Dust protection cover Mains cable

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
