S Plan Fluor ELWD Series

We are closely monitoring the situation with COVID-19 (coronavirus) and following the guidance of the Centers for Disease Control and Prevention (CDC) and federal, state and local health authorities. Learn more about the measures we have put in place.

 

Extra-long working distance (ELWD) objectives provide room to work with large samples and culture vessels.

These objectives feature high transmittance from near-ultraviolet to near-infrared wavelengths and extra-long working distance (ELWD) to accommodate large samples and culture vessels of variable thickness. The S Plan Fluor ELWD series provides a powerful balance of performance and flexibility, and are great for a variety of applications including calcium imaging. They are also well-suited for applications involving general fluorescence, brightfield, and DIC techniques.
