BRESSER ICD 30.5 mm Widefield Eyepiece 20x

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.

In addition to the objectives, eyepieces provide the magnification of the image. If using a highly magnifying eyepiece it's necessarily to ensure a sufficient illumination.Compatible with:BRESSER Researcher ICD (Art.-No. 5803100)BRESSER Biorit ICD (Art.-No. 5802000)BRESSER Biorit ICD LL (Art.-No. 5802510)BRESSER Biorit ICD CS (Art.-No. 5802520)BRESSER Advance ICD (Art.-No. 5804000)and other incident microscopes with the 30.5 mm eyepiece holder suitableFor a binocular microscope 2 eyepieces are necessary.SCOPE OF DELIVERYBRESSER WF 10x/30,5 mm Eyepiece

The Analyth STR Trino has 3 different objective magnifications that can be changed simply by turning the objective. This means that the magnifications 10x, 20x and 40x can be changed directly. The stereo design shows structured objects particularly vividly and three-dimensionally. The low,10x initial magnification is particularly suitable for working with children. Objects up to 20mm in size can be viewed in their entirety. The Analyth STR is therefore particularly flexible to use. It is suitable for insects, plants, minerals and much more and has its areas of application in hobby, school and work. The stereomicroscope can be used for quality control, in horticulture and agriculture, for hydrology and much more. The trinocular tube enables the comfortable connection of a camera. The microscope is compatible (depending on the adapter) for microscope cameras, SLR and system cameras. Ask us which adapter you need. The interpupillary distance and dioptric compensation 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 with the mains adapter or with 3 batteries (not included). This means that it can also be used on the move, for example outside in the garden or on an excursion.

The Analyth STR comes with 3 different magnifications, that can easily be switched by turning the objective. It is easy to change magnifications from 10x to 20x or 40x. The stereo microscope will show structured objects nicely in 3D, which is especially impressive. The low starting magnification of 10x is helpful when working with children and will show objects in full up to a size of 20mm. With the wide magnification range, the Analyth STR is a versatile instrument. You can use it to view insects, plants, minerals and much more. It is useful for hobbyists, in schools and more. Typical professional applications include quality control, gardening or farming (pest control), hydrobiology and much more.The interpupilllary distance and the diopters can be adjusted to your needs. The eyepieces feature a big field of view of 20mm. They are equipped with rubber eyecups and have a locking screw to prevent loss or damage during transport.The power supply can be achieved through the AC adapter or with a set of 3 AA type batteries (batteries not included). This makes the microscope  perfect for mobile use, e.g. outside in the garden or for biology field work.
