The KERN OBS-1 series consists of solid and simple school microscopes that are easy to handle thanks to their clear controls. The continuously dimmable 0.5 W LED ensures optimal illumination of the specimens and a long lifespan. Mobile use is also no problem due to the rechargeable batteries. The simple 0.65 condenser lens with a rotating aperture disc of the OBS 111 provides optimal light focusing and illumination of the sample. The OBS 114 and OBS 116 models feature a height-adjustable and thus focusable 1.25 Abbe condenser with an aperture diaphragm, which ensures optimal light bundling. Focusing on the object is achieved for all models through dual coarse and fine adjustments. Quick operation and movement of the specimen is facilitated by a mechanical stage (only with KERN OBS 106). A wide selection of different eyepieces and objectives is also available. Application area: Primary and secondary school, training, hobby. Applications/Samples: Translucent and thin, high-contrast, low-demand specimens (e.g., plant tissues, stained cells/parasites).
