  • Stand K – Compact, All-in-one, Including Illumination
    With its small footprint and integrated LED illumination, a K stand turns your ZEISS Stemi 508 into a compact all-in-one device that’s easy-to-use and quick to pack up and reinstall wherever it’s needed:
  • Stand K EDU is the smart choice for classroom environments with its flat transmitted light unit for bright- and darkfield.
  • Stand K LAB’s mirror-based transmitted light with the tiltable and shiftable mirror features brightfield, one-sided darkfield and oblique light – plus qualitative polarization contrast as an option.
  • Stand K MAT optimizes your Stemi 508 for quality inspection or small parts assembly with reflected light control and ESD features.

Compact, Reliable Greenough Stereo Microscope
For Excellent Image Contrast and Color Accuracy

Equipped with apochromatic optics you acquire images of outstanding image contrast and color accuracy. Its mechanics is designed for heavy workloads. With the large up to 36 mm object field you always keep the overview of your sample. The 8:1 zoom then allows to bring details up to 50× magnification. Add interchangeable optics and observe an area of up to 122 mm. Stemi 508 offers better ergonomics than any other Greenough-type stereo microscope: The low viewing angle of 35° lets you keep a relaxed posture even after hours of work.

Highlights:
Large Field of View and Apochromatic Correction

  • ZEISS Stemi 508’s apochromatic zoom optics* and efficient stray light suppression give you a crisp three-dimensional image, distortion-free, without color fringes.
  • Visualize objects in fields of view up to 122 mm.The large 8:1 zoom lets you observe even minute structures in high contrast.
  • Use interchangeable apochromatic front optics and eyepieces to reach any magnification between 2× and 250×. Double your resolution or enjoy large working distances up to 287 mm without compromising optical quality.

Precise Mechanics for Heavy Workloads

  • Stemi 508 is designed for heavy workloads, using durable and reliable mechanics.
  • Enjoy a well-balanced 3D impression: whether you zoom continuously variable or in reproducible mode by activating click stops – the image stays sharply focused over the whole magnification range.
  • Thanks to the low viewing angle of 35°, Stemi 508 is more ergonomic than any other Greenough-type stereo microscope. You appreciate a comfortable posture even if you work on the microscope for long hours.

Created for All Your Applications

  • Choose from compact stands to flexible and stable boom stands, from basic transmitted light to polarization contrast to get exactly what you need for your application.
  • Position your specimen precisely by adding a gliding, tilting or rotating polarization stage.
  • With Stemi 508 doc, there’s always a c-mount adapter for ZEISS Axiocam cameras included – interchangeable, to adapt any SLR camera or camcorder

Illumination
Reflected light illumination

  • LED spot K, zoomable and height adjustable, for oblique and grazing light illumination with strong shadow
  • Double spot arm gooseneck, self-carrying, for variable oblique light illumination with distinct shadow effect
  • LED segmentable ring light for shadow free ring illumination and oblique light segment illumination: half circle, quarter circle, two-spot

Transmitted light illumination

  • Flat transmitted light base for brightfield and darkfield illumination
  • Tiltable mirror base for brightfield, darkfield and oblique light illumination
