Navitar High Resolution (HR) Objectives
Same Resolving Power as High Resolution Lenses with Larger FOV
Navitar's HR Plan Apo Infinity Corrected Objective Lens Series includes magnifications of 1X, 2X, 4X, 6X, 10X and 20X. 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 436-656nm
- 95mm parfocal distance for turret compatibility
Large Field of View and Increased Throughput:
Field of view increase of 67% to 150% when compared to objectives with similar NA.
Higher Resolution:
Up to 30% increased resolving power over competing lenses with similar magnifications and fields of view.
System setup for above image captures: 160mm tube lens, Pixelink PL-D7620CU 20MP color camera and coaxial white LED illumination
