CFI Achromat Series for Phase Contrast

Excellent phase contrast imaging at an exceptional price.

CFI Achromat Series objectives for phase contrast microscopy. Correction for chromatic aberration in this series has been dramatically improved and is now at the same level as the CFI Plan Achromat Series. Images are crisp, clear and flat across 22mm field of view. These microscope objectives provide excellent phase contrast imaging at an exceptional price.
