Optical stereo microscope OSF 439

for teachingfor biologyinspection

Overview

• The KERN OSF-439 stereo microscope combines a Greenough optical system and a stable mechanical stand, designed for schools, workshops and industrial training.
• Integrated handle and robust mechanical support for easier handling and transport.
• LED incident (reflected) and LED transmitted illumination are included and continuously dimmable to adapt lighting to the sample.
• Turnable turret with predefined objectives (1×, 2×, 4×) speeds up magnification changes.
• Eyepieces 10× fixed in the tube to prevent loss or damage.
• Ergonomic working surface and coarse focusing provide comfortable and efficient operation.
• Delivery includes dust cover, eye cups and multilingual user manual.
