BRESSER 20x DIN Plan Achromatic Objective Lens

The BRESSER 20x DIN Plan Achromatic Objective Lens produces flat and even fields of view from edge to edge with little or no spherical aberration visible. It is parfocal with other 45mm length objectives, so there will be little or no focus adjustment required when changing magnifications. To make it easier to identify the magnification during use, the barrel is color coded green.
