Plan Semi-APO Objectives - IOS LWD U-PLAN F Series
IOS LWD U-PLAN (Plan Semi-Apochromatic) F PH objectives represent the state-of-the-art lenses for inverted microscopes, specifically developed for top-class performance and contrast required by the most demanding users.
Long Working Distance provides a wider working space between the objective front lens and the specimen, a benefit for a variety of samples, whilst the PLAN-Fluorite (or Semi-Apochromatic) design ensures additional spherical aberration correction for superior resolution and greater numerical apertures.
A superb resolution and contrast is granted especially for the observation of culture specimens in (positive) phase contrast method, but their versatility makes them an excellent product for other microscopic techniques, being very effective with UV fluorescence.
They are designed to ensure field flatness up to F.N. 25.
IOS LWD U-PLAN F PH objectives are designed for IM-3 and inverted modular systems.
