CELENA® S Objectives Selection Guide

Plan Achromatic Objectives
Plan achromatic objectives are corrected for axial chromatic aberration in two wavelengths, spherical aberration in the color green, and
flat-field aberration. The CELENA® TC PlanAchro Ph objectives are long working distance objectives that are suitable for routine brightfield,
phase contrast, and fluorescence imaging with most cell culture vessels.

Plan Fluorite Objectives
Plan fluorite objectives are produced from advanced glass formulations and provide a higher level of correction.
The CELENA® TC PlanFluor objectives are long working distance fluorite objectives that have been designed to be used with standard culture
vessels. These objectives are suitable for sensitive fluorescence imaging and higher resolution brightfield imaging.

Plan Apochromatic Objectives
Apochromatic objectives are corrected for chromatic aberration and spherical aberration in multiple colors.
The CELENA® Plan Apochromat Fluor objectives are exceptional objective lenses that can be used for highly sensitive fluorescence imaging
and the highest resolution imaging applications.

*LWD = Long working distance; for use with culture vessels with ~1 mm thickness
**Coverslip corrected = for use with coverslips with 0.17 mm thickness

CELENA® X Objectives Selection Guide

The CELENA® X is designed to be compatible with a wide range of objectives to accommodate specialized imaging applications.

* MAG = magnification; NA = numerical aperature; WD = working distance; BF = brightfield; FL = fluorescence; UV = ultraviolet; PH = phase contrast
