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

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

The resolution limit of the 40х/0.60 objective is 0.46µm.
Chromatic aberrations are corrected for blue and red light, spherical aberration for green light, and field curvature corrected to 90% of the field of view diameter.

The objective is infinity-corrected. The parfocal distance is 45mm. When working with a 10x/22mm eyepiece, the field of view diameter will be 0.55mm. Designed to work with samples without a cover glass.

The 40x metallurgical objective has a long working distance of 3.98mm. Working distance is the distance from the front lens of the objective to the object under study, at which the image of the object is in focus. Objects of study may have a pronounced topography, e.g., samples of printed circuit boards with different levels of electronic components and semiconductors. A large working distance prevents accidental damage to the front lens of the objective or sample when focusing and when turning the revolver to change objectives.

The lower limit of useful microscope magnification when working with a 40х objective is 300x. A lower magnification will not allow you to distinguish the details of the object in the image produced by the objective.
The upper limit of useful magnification when working with the 40х objective is 600x. Higher magnification is considered "useless" because it does not provide new detail in the image of the object.
With a 40x/0.60 objective, use eyepieces with magnifications from 7x to 15x.

Plan achromatic objectives produce an image equally focused in both the center and at the edges with minimal distortion. This feature is used for taking digital images and for working in conjunction with wide-field eyepieces with a 22mm field of view.
