BRESSER ICD 30.5 mm Widefield Eyepiece 20x

Slides and cover glasses are an indispensable accessory which has also impact on the image quality. For most biological microscopes, the cover glass thickness is an important optical parameter, which is therefore included in the optical design and, if so, printed on the sleeve of every objective. You can usually see the number 0.17 which is the thickness in millimeters. For demanding applications in the laboratory, or for microphotography, using cover glasses with the desired thickness and high quality is necessary.The cover glasses included in the set are made of Boro 3.3 glass and are standardized to a thickness of 0.16-0.19mm. So they match the desired 0.17mm really good and give the best possible image quality. These Boro 3.3 cover glasses are pure white, without streaks and are pre-cleaned and ready to use. They are also especially suitable for fluorescence microscopy.The slides are made of soda lime glass, and have ground edges for safe handling. They have a matte field for writing on both sides (top and bottom). Slides and cover glasses are packed separately and in a vacuum sealed bag, containing moisture absorbent. They can be stored for a long time without loss of quality from hydrolysis and are easy to take out.

Practical stereo microscope set for group observations. This set combines the Analyth STR-Rino stereo microscope with the MikrOkular LF Full HD. Thus, observation with multiple people is guaranteed.The microscope in detailThe Analyth STR Trino features 3 different objective magnifications, which can be easily changed by rotating the objective. The magnifications 10x, 20x, and 40x can be switched directly. The stereo design shows structured objects particularly vividly and three-dimensionally. The low 10x initial magnification is especially suitable for working with children. This allows objects up to 20mm in size to be viewed completely. The Analyth STR is therefore particularly flexible in use. It is suitable for insects, plants, minerals, and much more, with applications in hobbies, schools, and professions. The stereo microscope can be used for quality control, horticulture and agriculture, aquatic science, and much more.The trinocular tube allows for the comfortable connection of a camera. The microscope is compatible (depending on the adapter) with microscope cameras, DSLR, and system cameras.Ask us which adapter you need.The interpupillary distance and diopter adjustment are individually adjustable. The eyepieces have a large field of view of 20mm. They are equipped with removable rubber eyecups and secured against removal.The microscope can be powered either by the power supply or by 3 batteries (not included). This makes it portable, for example, outdoors in the garden or on an excursion.FEATURES OF THE MICROSCOPEMicroscope with 3 objective pairs, objective magnifications 1x; 2x; 4xWide-field eyepieces with eyecups and 20mm field of viewTrinocular tube with 23.2 mm receptacleBright, energy-saving LED lightingIllumination for reflected and transmitted light separately switchableDimmer via membrane keys with status displayTwo object plates (black/white or frosted glass), with specimen clipsDust coverUser manualStand with LED lighting, separately or together switchable or dimmableSCOPE OF DELIVERY OF THE MICROSCOPEMicroscope with 3 magnifications, 10x; 20x; 40xTrinocular tube, adjustableMetal stand with LED lighting, power supply, and battery compartment2 eyepieces with rubber eyecupsGlass object platePlastic object plate (black/white)Dust coverUser manualThe microscope camera in detailThis full HD microscope camera allows you to take photos and videos directly with the microscope. The MikrOkular LF can be inserted either instead of an eyepiece or into the third tube of the microscope. With the included adapter rings, the camera can be used on practically all microscopes instead of an eyepiece. Only for microscopes with an integrated C-Mount camera connection is the photo adapter 30.5mm / C-Mount (item no.: 5942030) additionally required.The Windows software available for download is easy to use and therefore suitable for beginners. It includes not only image and video capture but also a measurement function. The software is optimal for documentation in hobbies, schools, studies, and professions.Compared to the MikrOkular Full HD, the integrated reduction optics achieve about seven times the field of view based on the area. The camera's field of view corresponds approximately to that of a 10x eyepiece, a student microscope.FEATURES OF THE MICROSCOPE CAMERAMetal housing, USB-C socketIntegrated reduction optics for a larger field of viewResolution: 1920 x 1080 pixels, Full HDFrame rate: up to 25 fpsPixel size: 3x3 µm, sensor size: 5.86 x 3.28 mm23.2 mm plug size, integrated UV/IR filter30 mm and 30.5 mm microscope adapterMultilingual recording software for WindowsImage formats: jpg, tif, pngVideo format: MP4SYSTEM REQUIREMENTSWindows 10 or 11Intel i3, i5, i7 or i9 processor from 6th generation or higher or AMD FX or Ryzen processor from 1st generationInternet connection for software downloadMin.

The 10x eyepiece is suitable for all microscopes with 23.2mm eyepiece tube diameter. This diameter is widely used in stereo microscopes, also from other brands or manufacturers. Please select the eyepiece magnification in correspondence to the objective you are using. A low objective magnification allows for a higher magnification of the eyepiece. For example, combined with 4x or 10x objectives, eyepieces with 20x or 25x magnification can be used without loss of image quality. With a 100x objective, a 10x or 12.5x eyepiece is usually the highest recommended eyepiece magnification. To calculate the maximum useful magnification, consider the numerical aperture (N. A.) of the objective lens: numerical aperture of the objective lens x 1000 = max. useful magnification Here is a typical example: for a 10x objective with numerical aperture NA 0.25, a maximum of 250x magnification can be realized. This is realized with a 25x eyepiece. The numerical aperture is usually printed besides the magnification factor on many objectives. Magnifications beyond the max. useful magnification do not show any further details (so-called “empty magnification”) and are therefore not recommended.
