All in One, simple and practical

Streamlined appearance and focus-adjustable base equipped with multi-angle lighting. The operation interface is simple and intuitive. You can move the specimen, focus, or even switch and adjust the light source without leaving your eyes. Such a smooth and natural operating feel combined with the high-quality stereomicroscope optics from Zeiss, Germany, creates this ZEISS STEMI 305 EDU, ready for your work and exploration at any time.

Premium stereo optics from ZEISS

Zoom knob to enlarge, zoom ratio 5:1, magnification 0.8x ~ 4x, complete with freeze-frame design. Suitable for laboratories, biology classrooms, industrial production lines and other occasions. Using Greenough optical design, the image at the same position is imaged to both eyes through two optical paths, creating a three-dimensional feeling that still looks like direct vision after magnification.

Trinocular observation head

The observation head is equipped with a photographic connection, which is suitable for various types of photomicrographs and recorders. Pair it with a microscope camera and connect it to a monitor, mobile device or computer to take photos and videos and record observations instantly.

Integrate a variety of lighting to suit various tasks

Equipped with vertical epi-light, double-tube snake-neck LED light, and advanced transmissive bottom light with adjustable light and dark field of view and lighting angle. Multiple lighting options, corresponding to different observation situations. Observing the image patterns of samples under different light sources is also very suitable for observing the reflection of crystals from light sources at different angles. There is an adjustment button on the right side of the microscope holder that can be clicked and rotated to adjust and switch the light source in a unified manner, making the operation smooth and intuitive.

Unique vertical epi-illumination

The ZEISS STEMI 305 observation head has a built-in vertical incident light source and is uniquely designed to effectively illuminate targets with deep holes and observe the reflection pattern of light sources on the surface of the object being measured.

Advanced transmissive backlight with adjustable light and dark field of view and lighting angle

The stage is equipped with a penetrating light source, which can instantly change the light and dark field of view through the right lever. In dark field mode, rotate the lever to adjust the angle of the penetrating light below to optimize the lighting effect. The above operations do not require moving the observation object or dismantling the stage, and the operation is smooth.

A variety of lighting systems are available as optional extras

Compatible with various types of ring lights, snake neck lights, cold fiber optic conduit lighting... freely selectable according to usage needs.
