Olympus UPO-NIC Polarizer

The Olympus UPO-NIC is a rotatable polarizer for the Olympus BH2-UMA reflected light universal metallograph attachment on Olympus BH2 series upright microscopes. In reflected light polarized microscopy, the polarizer is placed in the incident light path before the specimen, producing linearly polarized illumination that strikes the specimen surface. When used in conjunction with an analyzer (placed in the reflected light path after the specimen), the polarizer and analyzer together enable polarized reflected light observation — revealing anisotropic features, grain orientation, birefringent phases, and surface characteristics of metals, minerals, and other opaque materials that are invisible or poorly contrasted in standard brightfield reflected light. The rotatable design of the UPO-NIC allows the polarization plane to be adjusted to any angle, enabling optimization of contrast for specific specimen orientations and features. The UPO-NIC is the correct OEM polarizer for the BH2-UMA universal metallograph illuminator — an essential replacement or spare component for researchers and institutions maintaining Olympus BH2 series metallograph systems in active service. This unit is in excellent condition at a significant discount from the list price.
