Objective MAGUS 40PLL 40x/0.60 Plan L WD 3.98 mm

MAGUS 40PLL 40x/0.60 Plan L WD 3.98 mm Objective
Plan achromatic objective corrected to infinity. Magnification: 40x. Aperture: 0.60

An objective with a 40x magnification and a maximum resolution of 0.46 µm. It is designed for installation on a metallurgical microscope. It can be used to observe objects with an uneven surface. To prevent damage to the lens surface under such conditions, the objective is designed for a long working distance of 3.98 mm. No cover slip is used when working with the objective.

The plan achromatic objective eliminates chromatic distortion for blue and red colors and spherical distortion for green. The field of view is wide and distortion-free due to the property of plan achromatic objectives to correct field curvature by 90%.

The objective is designed for infinity; its parfocality is 45 mm. It works well with eyepieces with a wide field of view (22 mm). The best image detail can be obtained with eyepieces with magnifications from 7x to 15x. When combined with a 10x/22 mm eyepiece, it will form a field of view of 0.55 mm. The useful magnification of the microscope when working with this objective will be 300–600x.
