Offering superb flatness of field, high UV transmission rates, and high Numerical Apertures with extra long working distances. 

CFI Plan Fluor ELWD objectives are well suited for fluorescence observations, especially with inverted microscopes. Because of their superior optical design, these objectives can be used universally for all other observation techniques, including brightfield, phase contrast, and Nomarski DIC. As a result of the extra long working distances, and their universal capability for imaging modalities, CFI Plan Fluor ELWD lenses are the best choice for critical high content and high throughput microscopy.
