ZEISS Stemi 355

ZEISS Stemi 355 is designed for a wide range of applications, including biology, material inspection, electronics, industrial quality control, and education.

Its large field of view, strong depth perception, and flexible magnification make it ideal for observing plant and animal samples, electronic components, small mechanical parts, and prepared materials. Whether used in schools, laboratories, training centers, or production environments, Stemi 355 provides reliable results across diverse sample types.

ZEISS Stemi 355 delivers high-contrast, distortion-free images with excellent depth of field. Depending on configuration and eyepieces, it provides a wide magnification range from 3.6x to 200x suitable for both overview inspection and detailed analysis. Users benefit from a large, bright field of view, allowing comfortable observation of three-dimensional specimens without constant refocusing.

Yes. ZEISS Stemi 355 is built for intuitive operation and requires no advanced training. Its ergonomic controls, quick focusing, and robust mechanics make it ideal for classrooms, shared laboratories, or environments with frequently changing users. Teachers and trainers especially appreciate that students can operate the instrument confidently within minutes.

ZEISS Stemi 355 supports multiple illumination options, including reflected, transmitted and oblique illumination as well as reflected light sources such as spot, double-spot or ring lights.

• Opaque samples (electronics, materials, insects): spot, double-spot or ring light
• Transparent samples (thin biological slides, small aquatic organisms): transmitted light
• Highly structured surfaces: ring light or flexible double-spot lighting

These options allow users to adapt lighting perfectly to the specimen type.

Yes. ZEISS Stemi 355 can be equipped with a compatible microscope camera via the phototube.

This allows users to capture still images, record video, or document results directly in digital form. If you decide for ZEISS Educam 105 for instance, you can also power the microscope camera via the USB-C interface directly from the stand.

Absolutely. When used with a suitable microscope camera, ZEISS Stemi 355 can stream live images to monitors, beamers, or interactive classroom displays. This is especially valuable for teaching, training sessions, lab demonstrations, or quality-control discussions where groups need to view the specimen simultaneously.

Typically, ZEISS Stemi 355 offers a generous free working distance of up to 110mm. Depending on the used front optics, the working distance can even be exceeded up to 185mm, providing ample space to manipulate tools, pipettes, small instruments, or samples beneath the optics.

This makes it well-suited for dissection, electronic assembly, fine manipulation tasks, and hands-on classroom activities that require room for movement.

Yes. ZEISS Stemi 355 in stand C Mat can be used in ESD-protected areas (EPAs) thanks to its antistatic surface and socket. This ensures safe operation in electronics manufacturing, repair, and quality-control environments where electrostatic discharge must be avoided.

In most cases, no special preparation is needed. Many samples such as plants, insects, small mechanical parts, or electronic components can be placed directly under the microscope:

• Biological specimens: live or fresh samples can typically be observed without additional preparation.
• Moist samples: avoid excessive condensation on lenses but normal surface moisture is usually fine.
• Soft or fragile specimens: simple stabilization (e.g., Petri dish, slide, or holder) may be helpful but not required.
  

This flexibility makes ZEISS Stemi 355 highly versatile for teaching, research, and routine inspection.
