CFI Plan Fluor Series

Objective lenses providing incredible high contrast fluorescence observation and photomicrography.

Featuring exceptionally high transmission from the ultra-violet to the infra-red and flatness across the field of view, the CFI Plan Fluor series objective lenses are designed for high contrast fluorescence observation and photomicrography. The performance and quality of Plan Fluor objectives make them a terrific choice as multipurpose objectives for brightfield, fluorescence, polarizing, and DIC observations.
