Different screens are available for certain applications. For example, the acrylic screen is suitable for food inspection applications.
Glass
Is the option “polarizer” activated, the Corona II generates linearly polarized light.
Light reflexes are eliminated almost completely in combination with a 90° rotated polarizer in front of the camera.
Glass with anisotropic foil
This option is available for darkfield applications only. The anisotropic foil avoids inhomogenious light distribution caused by reflections on the inspected object.
