The darkfield condenser allows you to render detail in specimens that would otherwise be transparent. Using principles of light-diffraction to suppress field-illumination, the cond enser illuminates edges of cells, microorganisms, and other objects. This is particularly useful for live blood analysis. This is a darkfield condenser designed for dry use with lower magnifications. The 0.9 maximum numerical aperture will accommodate lower-magnification objective lenses with numerical apertures up to 0.9. However, it is recommended to use objective lenses with numerical apertures below 0.7 for true darkfield. For magnifications above 40X, it is recommended to use the oil condenser. The condenser has two centering screws for properly aligning the illumination halo. This allows you to optimize the lighting on microscopes that do not have centerable condenser-holders. This condenser is designed to work with compound microscopes with a 37mm bottom-mount condenser holder. Compatible models include: B340, T340, B400, T400, B450, T450, B460, B490, T490, B590, T590, B600, T600, B680, T680, M220, M600 Condenser Compatibility Condenser Mount bottom mount Mounting Diameter 37mm Model Compatibility B340, T340, B400, T400, B450, T450, B460, B490, T490, B590, T590, B600, T600, B680, T680, M220, M600 Condenser Specifications Numerical Aperture 0.7-0.9 Immersion Medium none Centerable Optics Yes Show more
