All in One, simple and practical

It has a streamlined appearance, is equipped with a focusing base with multi-angle illumination, and integrates the ZEISS smart microscope imaging system. 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 high-quality stereoscopic microscope optics from Zeiss, Germany, creates this ZEISS STEMI 305T EDU Digital, ready for your work and exploration at any time.

An interactive biology classroom that breaks away from the traditional framework

The ZEISS Axiocam 208 smart microscope camera paired with the ZEISS Labscope photomicrography app allows you to unleash the full performance of your microscope. ZEISS STEMI 305T EDU Digital can quickly help teachers establish an interactive network of microscope images in the classroom. Just combine a mobile phone, tablet, and computer to view real-time images under the microscope. Supports wireless transmission and can be connected to multiple microscopes in the classroom simultaneously.

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.

Integrate a variety of lighting to suit various tasks

It has vertical downlight, lateral oblique light and transmitted bottom light. 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 305T observation head has a built-in vertical epi-illumination source and an exclusive design that can effectively illuminate targets with deep holes and observe the reflection pattern of light sources on the surface of the object being measured.

Multifunctional oblique lighting

The bracket of the EDU series models is equipped with a lateral oblique light source that can be lifted, adjusted, and focused. Manually adjust the height and angle of the light source directly along the track, and move the lamp head back and forth to focus the light source.

Transillumination with easy switching between bright and dark fields of view

The stage is equipped with a penetrating light source, and the light and dark field of view can be instantly changed through the lever on the right side. There is no need to move the observation object or disassemble 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.

Instantly record your learning and observations

ZEISS STEMI 305T EDU Digital can instantly output images under the microscope after being connected to the screen, and can quickly take photos, videos and image processing. The operation interface has built-in scale, measurement and up to 15 kinds of annotation functions to prepare for subsequent scientific analysis. Be fully prepared and use a variety of preset templates to quickly compile observation reports for easy sharing and recording.

Split windows for image comparison

The image file and the real-time microscope screen can be opened at the same time, and the two screens can be displayed at the same time to compare samples with each other and facilitate teaching demonstrations. When shooting, you can also capture the images in the split screen, output the observation report and annotate it.

Virtual laser pen function

The virtual laser pen function can be activated, and the light point of the virtual laser pen can be projected onto the large screen with a finger or cursor on the connected device to attract students' attention and guide them to pay attention to small structures and interesting details.

Augmented Reality Image-Tablet Only

Introducing the auxiliary function of AR augmented reality technology, combined with the rear lens image of the tablet, allowing you to compare the microscopic image being taken with books or charts, or overlay it on white paper to describe your observations Sample structure.
