OPTIKA B-510 Series includes a dedicated unit for immersion darkfield applications, used for fresh blood testing especially.
A ultra-modern, advanced routine microscope for transmitted light applications, featuring a 100x oil iris objective to be matched with the special darkfield condenser with integrated state-of-the-art, exclusive X-LED3 illumination, replacing any other external and expensive lighting source required for these applications.
OPTIKA immersion darkfield system provides the same result achieved by 150 W external illuminators in combination with traditional cardioid darkfield condenser.
The system achieves high numerical aperture for superb resolution delivering ultra-contrasted and sharp images through the impressive IOS W-PLAN optics.
When used in brightfield mode, the full Köhler system optimizes the microscope optical path to produce high sample contrast and homogeneous bright light, reducing image artifacts.
Darkfield is used to observe unstained samples causing them to appear brightly lit against a dark, almost purely black, background.
