Microscope Objective N PLAN 20x/0,40 POL
$undefined
The N PLAN objective class comprises further improved achromats with good field flatness up to 25 mm. N PLAN objectives are suitable for transmitted light and DIC, N PLAN PH for phase contrast. For incident light applications including differential interference contrast (DIC), N PLAN EPI objectives are available. The N PLAN EPI BD can also be used as a darkfield objective. The N PLAN EPI incident light objectives feature excellent image contrast and safe working distances.
