Podrobný popis

Polarizačný mikroskop MAGUS Pol 800

Zväčšenie: 40-600x. Trinokulárna hlava, rovinné achromatické objektívy. Osvetlenie prechádzajúcim svetlom, zdroj svetla – 30 W halogénová žiarovka, Köhlerovo osvetlenie. Bertrandova šošovka a kompenzátory

Polarizačný mikroskop Magus Pol 800 je skvelý na štúdium anizotropných  biologických, geologických a polymérnych vzoriek v polarizovanom a prechádzajúcom svetle. Trinokulárny mikroskop používa na vytvorenie obrazu dvojlom anizotropnej vzorky. Rovinne polarizované svetlo sa pri prechode anizotropným preparátom delí na dva lúče a mení rovinu polarizácie. Analyzátor privádza kmitanie lúčov do rovnakej osi a roviny, zásluhou čoho dochádza k deštruktívnej a konštruktívnej interferencii medzi oboma vlnoplochami. Jasný, vysoko kontrastný obraz mení farbu, keď budete otáčať pracovným stolíkom. Mikroskop vlastní objektívy bez vnútorného pnutia. V medziľahlom tubuse sa nachádza analyzátor a Bertrandova šošovka, ktorá má slot pre kompenzátory. Je ideálny optickým prístrojom v odboroch mineralógii, kryštalografii, petrografii, súdnom lekárstve, medicíne a iných vedných odboroch.

Polarizing microscope MAGUS Pol 800
Magnification: 40-600x. Trinocular head, planar achromatic objectives. Transmitted light illumination, light source – 30 W halogen lamp, Köhler illumination. Bertrand lens and compensators

The Magus Pol 800 polarizing microscope is great for studying anisotropic biological, geological and polymer samples in polarized and transmitted light. The trinocular microscope uses the birefringence of an anisotropic sample to create an image. Plane-polarized light is split into two beams when passing through an anisotropic preparation and changes the plane of polarization. The analyzer brings the oscillations of the beams to the same axis and plane, due to which destructive and constructive interference occurs between the two wavefronts. The bright, high-contrast image changes color when you rotate the worktable. The microscope has lenses without internal tension. The intermediate tube houses the analyzer and a Bertrand lens, which has a slot for compensators. It is an ideal optical instrument in the fields of mineralogy, crystallography, petrography, forensics, medicine and other scientific fields.

Polarizing microscope head

The microscope has a trinocular head with planar achromatic objectives with infinity correction. The trinocular tube houses the digital image capture devices. The eyepiece/camera light path selector knob allows you to direct the light beam either to a digital camera or to the eyepiece tubes. You can adjust the diopters on the left tube.

Revolver objective holder

The revolver objective holder has 5 slots for placing objectives. An additional objective can be mounted in the free slot to achieve even greater magnification. Thanks to the design of the revolver objective holder, which is directed away from the observer, it frees up space in the front of the work table, so you will see the objectives inserted into the optical path. The slots of the revolver objective holder are centered so that the optical axis of the objective and the microscope are aligned. Plan achromatic objectives with infinity correction are designed for observation in polarized light. The strain-free optics ensure that the birefringence comes from the specimen under examination and not from the optical elements. It is designed for use with coverslips with a thickness of 0.17 mm.

Mechanizmus zaostrovania trrinokulárneho mikroskopu

Focusing mechanism of trinocular microscope

The coaxial coarse and fine adjustment knobs of the MAGUS Pol 800 microscope are located at the bottom of the microscope stand on both sides. This allows you to comfortably place your hands on the table and take a relaxed position while working. Focus adjustment is easy and smooth. The design of the focusing mechanism allows you to quickly adjust the microscope after changing the specimen under examination. The coarse focus locking knob is located on the right side. The stiffness of the coarse focus can be adjusted by turning the ring on the left side.

Pracovný stolík mikroskopu

Microscope Stage

The stage can be rotated 360°, allowing you to observe the color change of the sample when the polarizer and analyzer are in a crossed orientation. The scale features a rotation angle graduation. Using the vernier scale, your measurement will be accurate to 0.1°. The stage can be centered using two screws, as analyzing an anisotropic object in polarized light requires precise alignment of the stage rotation axis with the optical axis of the microscope.

Zdroj svetla mikroskopu a osvetlenie

Microscope light source and illumination

Halogen bulbs emit light with a warm color tone, so your eyes will not get tired even during long work. The illumination source is a 30 W bulb, which provides sufficient brightness for observation with objectives with magnifications of 4x to 100x, which are used for bright field and polarized light microscopy. Köhler illumination - adjustable field diaphragm, centered and height-adjustable Abbe condenser with adjustable aperture diaphragm and rotating auxiliary lens. NA=1.25. The polarizer is rotatable by 0–360°, four rotation angles are marked on the scale, namely 0°, 90°, 180°, 270°. The analyzer rotates by 90° and the vernier scale on the analyzer allows you to accurately measure the angle.

Köhler illumination

Setting up Köhler illumination significantly improves image quality when examining a sample. This illumination allows for maximum resolution on each objective and ensures uniform illumination of the field of view without darkening at the edges. The studied object is focused with high sharpness, thus eliminating image artifacts.

Studying samples in polarized light

The intermediate tube contains the analyzer and the Bertrand lens, which has a slot for compensators. The analyzer is inserted into the light path so that you can observe objects in polarized light. When the polarizer and analyzer are rotated, the polarization angle changes. You can achieve a mutually perpendicular position by setting both filters to the “0” position. When the stand is rotated, the light is reflected differently from the surface of the specimen depending on the polarization angle. The Bertrand lens is ideal for conoscopic examination. Compensators are suitable for increasing the contrast of specimens with weak birefringence.

Accessories available for purchase

A wide range of accessories specially designed for this microscope is available. Additional objectives can be used to study objects down to 0.22 µm. Eyepieces extend the magnification capabilities of the microscope, while additional eyepieces allow you to fully exploit the potential of the most frequently used objective. A digital camera that transmits the image from the microscope to a monitor, stores files and is equipped with software for real-time sample measurement. A calibration slide for object measurement can be combined with an eyepiece with a scale or with camera software.
