ZEISS Stemi 508, trino, 50:50 Greenough, w.d. 92mm, 10x/23, zoom 8:1, 0.63x-5.0x, LED (62085, 435064-9031-000 (435064-9030-000))

ZEISS Stemi 508, Trinocular 50:50, Greenough, Working Distance 92 mm, 10x/23, Zoom 8:1 (0.63x–5.0x), LED (62085, 435064-9031-000 / 435064-9030-000)

The Stemi 508 is a compact and durable Greenough stereo microscope designed for demanding laboratory and industrial applications. Its apochromatic optics provide excellent image contrast and accurate color reproduction. Built for continuous use, this microscope offers a large object field of up to 36 mm, allowing entire samples to be viewed at once.

With its 8:1 zoom system, the Stemi 508 achieves magnifications up to 50x. When combined with interchangeable optics, observation fields of up to 122 mm in diameter are possible. The ergonomic 35° viewing angle ensures a comfortable posture, even during extended periods of work.

This microscope enables both precise visual inspection and professional documentation of specimens, delivering sharp, detailed images free from distortion and chromatic aberration. It is a reliable and versatile instrument for daily laboratory tasks and industrial inspections.

Wide Field of View and Apochromatic Correction

• Apochromatic zoom optics with effective stray light suppression produce sharp, three-dimensional images without optical distortion or color fringing

• Observation field up to 122 mm in diameter

• Wide 8:1 zoom range for high-contrast viewing of fine structures

• Interchangeable apochromatic front optics and eyepieces allow magnifications from 2x to 250x

• Option to increase resolution or achieve working distances up to 287 mm without compromising optical quality
