Olympus ACH N 20x/0.40 P Polarized Light Objective – Strain-Free Microscope Lens

The Olympus ACH N 40x objective is specifically engineered for polarized light microscopy, featuring strain-free optical construction essential for accurate analysis of birefringent materials. Polarized light microscopy requires objectives manufactured with special attention to internal strain, as any stress-induced birefringence in the objective's optical elements would interfere with specimen analysis. This objective's strain-free design ensures that observed birefringence patterns originate solely from the specimen, not from the optics, enabling accurate identification of minerals, crystals, polymers, and other anisotropic materials. At 40x magnification with 0.65 numerical aperture, this objective delivers excellent resolution and light-gathering capability for detailed examination of crystalline structures, grain boundaries, and optical properties. The achromat optical design provides reliable chromatic correction suitable for polarized light applications. The 0.45mm working distance accommodates standard microscope slides with coverslips. The RMS thread mount ensures compatibility with Olympus BX and CX series polarizing microscopes as well as other RMS-threaded platforms. Factory-new condition ensures optimal performance and reliability for demanding geological, materials science, and industrial applications requiring precise polarized light analysis.
