AmScope Darkfield Condenser and Objective Set for 670 Series Compound Microscopes en Irvine, California, USA

Set of 2 Darkfield condensers for our 670 series compound microscopes
100X Infinity-corrected Plan Achromatic Objective with Iris
Improve contrast in translucent specimens
Both dry and oil condensers for low and high magnifications
This is a darkfield condenser and objective set for our T670 microscopes. Both dry and oil condensers are included to cover a wide range of magnifications and numerical apertures. The dry condenser, with an NA of 0.7-0.9 is best-suited for lower-magnification objectives, typically up to 40X. The oil condenser has a maximum NA of 1.36, and is necessary for higher-magnification objectives. As well, the oil condenser will produce brighter highlights. A variable-aperture 100X objective is also included, to better control contrast at the highest magnification. Because darkfield uses oblique light explicitly, an objective lens’ numerical aperture must be significantly lower than that of the condenser to optimize contrast.
