OPTICS Infinity Flat-Field Objectives Developed with high-contrast infinity PLAN objectives, the Innovation microscope produces sharp, crisp, flat-field images across the entire field of view. Whether spending hours scanning cytologies or counting differentials, a flat field of view will ensure that the critical cells at the edge of view are just as clear and focused as those cells in the middle. The infinity optical system, as found on the most expensive research microscopes, is the premium platform for the highest contrast and resolution. Objective Choices The 4-objective model features the most common configuration - 4x-10x-40x-100x (oil) - on a 4-hole reverse nosepiece. The reverse nosepiece allows for greater access to slides for quick changes. Affordably priced, this model fits the needs of most universities and clinics. The 5-objective model is ideal for laboratory and research use. It offers a 4x-10x-20x-40x-100x (oil) configuration on a 5-hole reverse nosepiece.
