Navitar High Resolution (HR) Objectives
Navitar's HR Plan Apo Infinity Corrected Objective Lens Series includes magnifications of 1X, 2X, 4X, 6X and 10X. These lenses offer:
-
More resolving power at a larger FOV - High NA design
-
Long working distance for room to manipulate specimens
-
Contrast improvement - Apochromatic over 430-656nm
-
95mm parfocal distance for turret compatibility
Large Field of View: These objectives provide a field of view increase of 67% to 150% when compared to objectives with similar numerical apertures (NA), providing increased throughput for image processing.
Higher Resolution: These infinity corrected, apochromatic objectives offer up to 30% increased resolving power over competing lenses with similar magnifications and fields of view.
