IOS W-PLAN PH (Plan Achromatic) objectives deliver outstanding performance in phase contrast technique, providing a great contrast generally equired in high-level education and routine laboratory needs. These phase contrast objectives are designed to ensure field flatness up to F.N. 22, based on infinity-corrected optical system.
IOS W-PLAN PH objectives are designed for B-380, B-510 and upright modular systems with phase contrast, and infinity-corrected optical
