The Motic K Series stereo microscopes are high-performance, modular systems purpose-built for today's rapidly changing microscopy landscape. Engineered around a common main objective (CMO) and infinity optical system, the K Series delivers sharp, high-resolution upright images for observation and documentation. The modular design offers easy adaptation with elements like an optional photo/video tube to document a variety of working environments, ranging from routine quality control to biological research and more.


As an upgrade from the K-400, the K-401 features a full Plan Achromatic 1X objective for clear, distortion-free images. The Infinity optical system is fully parfocal and offers a crisp, three-dimensional upright image through a binocular head inclined 45 degrees and rotatable 360 degrees. Super Widefield 10X FN 23 eyepieces offer 54mm-76mm of interpupillary adjustment and +/- 5 degrees of dioptric adjustment, allowing fatigue-free viewing for multiple users.

The Plan Achromatic objective is housed in a 4-position turret changer with click-stop detents to ensure precise, repetitive observation at 6X, 12X, 25X and 50X magnification, 110mm working distance and 38mm max. FOV. Optional eyepiece and objective lens combinations offer 0.9X to 320X total magnification.

Focus & Illumination

Dual rack and pinion focus controls are conveniently positioned and feature tension adjustment for responsive and predictable movement. Incident and transmitted illumination is independently controlled by variable intensity, 12V10W halogen.


The K-401 is available here with a choice of two popular bases, the economical 2112 base with natural incident illumination, or the FBGG base with integrated 12V10W dual halogen illumination. Each stand features a 32mm vertical post and a wide platform base offering a large, 330mm x 280mm working surface with chemical-resistant finish. Black/white and frosted stage plates and 2 spring clips are included. For additional mounting options, please call 877-409-3556.


Accessories include a blue filter, manual and dust cover.
