BRESSER Single Polarizing Filter 2"

Herschel-wedge / Solar-wedge for superior White-Light solar observing and imaging. For refractor-telescopes up to 150mm aperture, and with 2'' focuser. Complete system with installed ND3.0 filter.Herschel-Wedges will be used to observe the sun in White-Light. Around 95 % of the sun light will be suppressed by the Herschel Wedge. The remaining sun light will be dimmed by a fix installed ND3.0 grey filter. Lunt Solar Systems Herschel-wedges are installed in a fully closed housing with integrated heat trap. There is no stray light escaping, therefore it is very safe.The difference between Herschel-wedges and normal front mounted filters is, that the filtering takes place just before the eyepiece or camera. This will provide a better contrast and sharpness of the solar image.Furthermore, there is more safety at a Herschel-wedge than at a front mounted filter. A Herschel-wedge can not rip or become holes like a foil. And also it can not drop down from the telescope objective accidentally.Only for use with refractor telescopes up to 150mm aperture:Because the full energy and heat of the sun will be inside the telescope, we advise to use only refractors with a Herschel-wedge. The refractor must not have corrector lenses at the back. Optical elements like corrector lenses, or secondary mirrors of reflector telescopes, become very hot by the concentrated solar energy and could be damaged.Tuning the brightness:Because the Herschel-wedge produce polarized light, you can use a normal polarizing filter at the eyepiece or camera-adapter. By turning the polarizing filter the brightness will be reduced.Polarizing filter not included.

The zoom stereo microscope BRESSER Advance ICD is suitable for a wide variety of objects. Because of the Greenough design with two tilted objectives, you can view the sample in 3D. The three-dimensional view is also very helpful when working under the microscope, e.g. when soldering, dissecting or preparing a sample.The precise zoom enables you to view your sample in a wide range of magnifications from 1x to 4x (zoom ratio 4.0). When zooming, only slight refocussing is necessary. To do this, the Advance ICD microscope is equipped with a very precise, coaxial coarse and fine focus. The fine focus is especially helpful when using high magnifications or for imaging. When doing focus stacking with our MikroCam cameras (optional) the fine focus is also a big help.The interpupillary distance of the eyepiece pair is adjustable. Both eyepiece holders are equipped with diopter adjustment, which allows users with bad eyesight to compensate up to 8 dpt. difference between left and right eye. The 10x wide field eyepieces have field number (FN) 22 and are equipped with soft rubber eyecups. The microscope head can be moved on the long rod of the stand, which allows you to observe big samples up to a size of 22 cm.The angle of the bright LED reflected light illumination can be adjusted as necessary. The extra bright and even LED transmitted light provides a flat background when viewing transparent samples. The switch allows you to select reflected light, transmitted light or a combination of both to match your requirements. Brightness is adjustable with the dimmer. The bright light does not heat up, which allows you to observe also living specimens over a longer period of time. The long lasting LED is powered by a 5V AC adapter (EU/UK). The power cable comes with a USB plug.Fully equipped, the Advance ICD covers an exceptionally wide range of magnifications and is therefore suitable for a variety of tasks. Besides the included 2x lens there is also a selection of other auxiliary objectives available. With these, you are able to adjust magnification, working distance and depth of focus according to your needs.Magnifications in basic setting (no optional accessories):10x eyepieces: 10x – 40x10x eyepieces plus 2x auxiliary lens: 20x – 80x20x eyepieces: 20x – 80x20x eyepieces plus 2x auxiliary lens: 80x – 160x(other magnifications are possible when using other auxiliary lenses and/or eyepieces)The third tube is designed to permanently attach a camera. The image of the left eyepiece is diverted to the camera port with a lever/switch. We supply a selection of camera adapters for DSLR, mirrorless cameras and c-mount microscope cameras. This enables you to attach virtually any camera body as long as you have a model with interchangeable lens.APPLICATION RANGEQuality control in industryMaterials scienceLaboratoryBotany, gardening, farmingHydrology, aquaculture, fishkeepingInsects, Entomology, pest controlPlant physiology, raw food materials, medicinal herbsSchools, teachingFEATURESTrinocular head with 2 eyepieces and camera port with switchCompatible with BRESSER MikroCam cameras and others1x-4x stereo-zoom head2x auxiliary lensDiopter adjustment on both eyepiece holdersAdjustable interpupillary distance (52 – 72 mm)Bright LED light (reflected / transmitted)2 different object plates for best contrastView samples of up to 22 cm heightAC adapter Euro/UK (5V / 1000 mA) with USBHeavy build with metal standIncludes 2 pairs of widefield eyepiecesSCOPE OF DELIVERYMicroscope2 pairs of eyepieces (WF 10x / WF 20x)2x auxiliar lens (1 pcs)1 pair of rubber eyecupsObject plate 94 mm (black / white)Glass object plate 94 mm (matte)AC adapter Euro/UK (5V / 1000 mA)Dust coverPrinted manual
