MAGUS Stereo D7T PLUS Digital Stereomicroscope

The stereomicroscope with the Greenough optical design provides accurate details of the surface topography with no loss of spatial orientation, ensuring a large depth of field when observing three-dimensional objects.

The microscope smoothly changes magnification by a factor of 6.7 between 6.7x and 45x while maintaining a working distance of 105mm. It has built-in transmitted and reflected light illuminators for studying translucent and opaque objects. The microscope provides for the installation of polarized light and darkfield accessories.

The camera in the digital microscope allows the recording of the observation process as well as its intermediate and final outcomes. The 20MP sensor delivers the required resolution on the stereomicroscope. The 1" sensor with a 1x adapter displays a field of view of 19.5x13.1mm on the computer screen with the microscope’s lowest magnification.

The microscope is used for restoration, assembly, and quality control as well as in zoology and botany.

Digital camera

MAGUS CDF70 digital camera features low noise and high light sensitivity. The camera is suitable for operation over the full magnification range of the microscope objective, ranging from 0.67x to 4.5x.

The sensor size is 1". Therefore, a 1x C-mount adapter is used for mounting a camera on the microscope. On such a sensor, the 1x adapter is intended to “show as large a field of view as possible with no distortion”.

The 20MP sensor produces a realistic image in 5440x3648px. At this resolution, the frame rate is 20fps, which is enough to fine-tune the focus of the microscope.

At resolutions of 2736x1824px and 1824x1216px, the rate increases to 48fps and 58fps, respectively. Transitions between frames become smoother and the camera captures small movements of the object. These modes are suitable for classroom demonstrations, video recording, and observing moving objects.
The USB 3.0 provides 10 times faster data transfer rates than USB 2.0.

Microscope head

The trinocular head is 360° rotatable and can be locked in any desired position. The digital camera is mounted in the trinocular tube using a C-mount adapter.

The light path does not change. The splitting ratio is fixed: 80% to an eyepiece and 20% to the trinocular tube. The user observes the image in the eyepieces and on the screen at the same time.

The basic configuration includes 10x/22mm eyepieces with diopter adjustment and eye relief to work with glasses.

Zoom objective

The objective allows for the smooth change of magnification up to 6.7 times with no loss of focus while maintaining a large working distance of 105mm. The microscope generates an upright (not inverted) three-dimensional image. Auxiliary objective lenses change the magnification range, field of view, and working distance of the microscope.

Focusing mechanism

Coarse focusing knobs are located on both sides of the stand. The coarse focusing tension is adjustable.

Stage plate

A frosted glass or black-and-white plate is selected depending on the specimen. The frosted glass plate ensures even illumination and optimal light scattering when transparent and translucent objects are observed. The black-and-white plate is selected for observing opaque objects against a contrasting background: the black side for light objects and the white side for dark objects.

Light sources

The microscope has a 3W LED transmitted light illuminator and a 3W LED reflected light oblique illuminator. The LED lifetime is 50,000 hours.

Accessories

There is a wide range of accessories for the microscope.

Eyepieces and auxiliary objective lenses extend the magnification range of the microscope.

Digital cameras output images from the microscope to a monitor.

C-mount adapters connect a camera to a microscope. The adapter magnification is selected to match the camera sensor size.

Calibration slides are used for measuring specimens. The scale value on the calibration slide of stereomicroscopes is 0.1mm.

A polarizer/analyzer set is used to study anisotropic samples.

The darkfield condenser with a gem clip allows for studying precious and semi-precious stones.

A ring light is used to provide shadow-free lighting in the working area in reflected light.

A ring light with a polarizer removes glare from the image of polished metal surfaces.

A mechanical stage enables the smooth movement of specimens with no jerks along two axes and offers additional convenience to the user when magnifications above 20x are used.

A ring light with sector control and a gooseneck light are used to fine-tune the illumination in the working area. The light is exposed at a selected angle, creating the light shadows required for the observations, while a certain part of the specimen remains illuminated.

Universal stands allow you to enlarge the working area, thereby giving you more freedom in choosing the position of the microscope head above the workstation.
