Objective Lenses
CFI60-2 Objectives
CFI60-2 objectives are newly evolved from the established CFI60, with its high NA and long working distance.
Employing Nikon’s unique phase Fresnel lens, CFI60-2 objectives have a long working distance and achieve highly corrected chromatic aberration for sharp, clear images.

CFI60 Objectives
These objectives have been designed for the CFI60 system, Nikon’s proprietary optical system combining infinity optics with the superior performance of the CF optical system. The advantage of the parfocal distance of 60mm, a new standard, has been utilised to lengthen working distance while maintaining high NA, producing images that are crisp and clear with high contrast and high resolution.
