LBTEK offers Olympus Plan Semi-Apochromatic Objective Lenses, which feature standard RMS threads and are designed with an infinity-corrected Plan Semi-Apochromatic design for tube lenses with a focal length of 180 mm. The Plan Semi-Apochromatic Objective typically uses fluorite (CaF2) material, also known as Plan Fluorite Objectives, and its chromatic aberration correction performance is between that of Plan Achromatic and Plan Apochromatic objectives. LBTEK provides Olympus-produced Plan Semi-Apochromatic Dry Objective Lenses with magnifications of 4X, 10X, 20X, 40X, 50X, 60X, and 100X, as well as oil immersion objectives with magnifications of 60X and 100X.
LBTEK offers Olympus-produced Plan Semi-Apochromatic Dry Objective Lenses with magnifications of 4X, 10X, 20X, 40X, and 60X (with correction collar). Each lens is equipped with standard RMS threads and can be mounted onto holders with SM1 internal threads using LBTEK's SM1-RMSA thread adapter. These five models of Plan Semi-Apochromatic Dry Objective Lenses are highly suitable for brightfield microscopes, and the 10X, 20X, 40X, and 60X magnification models are also very suitable for Differential Interference Contrast (DIC) microscopes. Specific parameters can be found in the product specification table below.
