Objective lenses are precision optical components designed for high-resolution imaging, microscopy, laser processing, and scientific applications. Available in Plan Achromatic, Semi-Apochromatic (Fluorite), and Plan Apochromatic types, they offer different levels of chromatic and spherical aberration correction to ensure sharp, flat, and color-accurate images.
LBTEK provides a wide range of infinity-corrected objectives including Olympus, Nikon, Mitutoyo, long working distance, immersion (dry, oil, water), and high-power laser objectives. With multiple magnifications (4X–100X), thread standards (RMS, M26, M32), and compatibility with 180 mm and 200 mm tube lenses, these objectives are ideal for microscopy, precision measurement, industrial inspection, and laser-based imaging systems.
