ZEISS Stemi 305.SF

The simplest, most stable, and most economical matte combination, paired with high-quality stereoscopic microscope optics from Germany’s Zeiss and HDMI high-definition M2 microscope camcorder. Suitable for users who require special light sources, use fiber optic illumination, or need to process observation samples.

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.

Unique vertical epi-illumination (needs to be used with ZEISS original dimmer)

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.

40x30cm SF large base

The SF base has an operating space of 40x30cm. The lifting adjustment mechanism can lift (height) 278mm on the column, and the working distance is flexible. It is suitable for observing large samples or processing samples. You can also purchase an auxiliary mirror to increase the vertical working space for your hands.

Two sizes of focus brackets - to suit your needs

You can choose between single-speed and double-speed focusing brackets according to your needs.

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.
