Overview

The KAAS KS-125D / KS-300D Series Binocular Biological Microscope is designed for comfortable, precise and dependable specimen observation in laboratories, universities, medical facilities and educational environments.

Both models feature a 30° inclined Siedentopf binocular viewing head, wide-field eyepieces, a large double-layer mechanical stage and accurate coaxial focusing controls. The ergonomic viewing position and adjustable interpupillary distance help reduce eye and neck strain during extended observation.

The KS-125D uses a finite optical system with achromatic objectives, while the KS-300D features an infinity optical system with semi-plan achromatic objectives for improved flatness and clarity across the field of view.

Model Selection

KS-125D Finite Biological Microscope

The KAAS KS-125D uses a finite optical system with standard achromatic objectives. It provides dependable performance for routine biological observation, laboratory training and educational applications.

Its backward-facing nosepiece offers convenient access to the objectives, while the large mechanical stage and 25 mm focusing range support smooth and accurate specimen examination.

KS-300D Infinity Biological Microscope

The KAAS KS-300D features an infinity optical system with semi-plan achromatic objectives. This configuration provides improved field flatness and clearer imaging across a wider observation area.

The centreable N.A. 1.25 condenser, precise coaxial focusing controls and adjustable S-LED illumination make it suitable for more demanding research, medical and laboratory applications.
